Title: Computerized systems and methods for improved mobile worker tracking

Description:
TECHNICAL FIELD 
     The present disclosure generally relates to computerized systems and methods for tracking the time worked by users. In particular, embodiments of the present disclosure relate to inventive and unconventional systems relate to logging time in and out for users, including an automated system of reminders and limits. 
     BACKGROUND 
     The present disclosure relates to computerized systems and methods for tracking time worked by users. These systems enable employers to track the number of hours their employees work, track the productivity of employees, and ensure that employees do not work beyond their allotted time to help comply with employment laws. 
     Prior art systems require employees to log in and log out from a centralized location. For example, employers used to require employees to “punch-in” when they arrived at work, and thus began tolling the employee&#39;s time they worked. This system used a punch card that the employee inserted into a machine. The machine punched the card to mark the time the employee started working. When the employee stopped working, the employee then inserted the card again and the machine marked the time the employee stopped working. This system is limited by the number of punch machines the employer provides, often creating lines of employees waiting to punch in and out. 
     As technology advanced, the punch card system was replaced with electronic systems. For example, electronic time tracking systems used a computer terminal to allow a user to log in and log out, corresponding with a punch-in and punch-out. Similar to the punch card system, such systems are inconvenient—they are limited by the number of computer terminals, can result in slow processing of time information while employees wait to log in and log out, and can become a point of failure for an entire department or building of workers if the system goes down. In addition to causing technical problems, these backups can slow down internal and external processes and hurt worker productivity. 
     Therefore, there is a need for improved methods and systems for allowing employees to log in and log out of a system to track the hours the employees work. The system disclosed herein allows employees to use mobile devices, such as mobile phones, to log in and log out, eliminating the back up and delay of the old systems. 
     SUMMARY 
     One aspect of the present disclosure is directed to a computer-implemented device for tracking a user&#39;s time, the device comprises a memory storing instructions, a network device, a display device, and at least one processor configured to execute instructions. Those instructions include determining a location of the device based on one or more network signals from the network device; based on the determined location, displaying on the display device a first user interface element that, when selected, records a start time associated with a user identifier; receiving, from the display device, a selection of the first user interface element; after receiving a selection of the first user interface element, displaying on the display device a second user interface element that, when selected, records an end time associated with a user identifier; and sending at least one of the first time or the end time to a remote server via the network device. 
     In another embodiment, displaying the first user interface element is based on determining that the current time is within an accepted time. In another embodiment, the accepted time is based on at least one of a vacation schedule, a shift schedule, or a needed capacity. 
     In another embodiment, the instructions further cause the at least one processor to receive, from a remote server, an amount of time worked by the user during a first time frame; determine whether the amount of time worked is greater than a maximum amount of time for the first time frame; and based on the determination, prevent the display of the first user interface element. In another embodiment, the instructions further cause the at least one processor to display a warning when the amount of time worked within the first time frame exceeds a threshold amount of time that is smaller than the maximum amount of time. In another embodiment, the instructions further cause the at least one processor to display a warning when the amount of time worked within the first time frame exceeds the maximum amount of time within the first time frame.

     DETAILED DESCRIPTION 
     The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar parts. While several illustrative embodiments are described herein, modifications, adaptations, and other implementations are possible. For example, substitutions, additions, or modifications may be made to the components and steps illustrated in the drawings, and the illustrative methods described herein may be modified by substituting, reordering, removing, or adding steps to the disclosed methods. Accordingly, the following detailed description is not limited to the disclosed embodiments and examples. Instead, the proper scope of the invention is defined by the appended claims. 
     Embodiments of the present disclosure are directed to systems and methods configured for allowing users to log in and out to track time worked, and providing alerts and other time controls to prevent users from working too many hours. 
     Referring to  FIG. 1A , a schematic block diagram  100  illustrating an exemplary embodiment of a system comprising computerized systems for communications enabling shipping, transportation, and logistics operations is shown. As illustrated in  FIG. 1A , system  100  may include a variety of systems, each of which may be connected to one another via one or more networks. The systems may also be connected to one another via a direct connection, for example, using a cable. The depicted systems include a shipment authority technology (SAT) system  101 , an external front end system  103 , an internal front end system  105 , a transportation system  107 , mobile devices  107 A,  107 B, and  107 C, seller portal  109 , shipment and order tracking (SOT) system  111 , fulfillment optimization (FO) system  113 , fulfillment messaging gateway (FMG)  115 , supply chain management (SCM) system  117 , workforce management system  119 , mobile devices  119 A,  119 B, and  119 C (depicted as being inside of fulfillment center (FC)  200 ), 3 rd  party fulfillment systems  121 A,  121 B, and  121 C, fulfillment center authorization system (FC Auth)  123 , and labor management system (LMS)  125 . 
     SAT system  101 , in some embodiments, may be implemented as a computer system that monitors order status and delivery status. For example, SAT system  101  may determine whether an order is past its Promised Delivery Date (PDD) and may take appropriate action, including initiating a new order, reshipping the items in the non-delivered order, canceling the non-delivered order, initiating contact with the ordering customer, or the like. SAT system  101  may also monitor other data, including output (such as a number of packages shipped during a particular time period) and input (such as the number of empty cardboard boxes received for use in shipping). SAT system  101  may also act as a gateway between different devices in system  100 , enabling communication (e.g., using store-and-forward or other techniques) between devices such as external front end system  103  and FO system  113 . 
     External front end system  103 , in some embodiments, may be implemented as a computer system that enables external users to interact with one or more systems in system  100 . For example, in embodiments where system  100  enables the presentation of systems to enable users to place an order for an item, external front end system  103  may be implemented as a web server that receives search requests, presents item pages, and solicits payment information. For example, external front end system  103  may be implemented as a computer or computers running software such as the Apache HTTP Server, Microsoft Internet Information Services (IIS), NGINX, or the like. In other embodiments, external front end system  103  may run custom web server software designed to receive and process requests from external devices (e.g., mobile device  102 A or computer  102 B), acquire information from databases and other data stores based on those requests, and provide responses to the received requests based on acquired information. 
     In some embodiments, external front end system  103  may include one or more of a web caching system, a database, a search system, or a payment system. In one aspect, external front end system  103  may comprise one or more of these systems, while in another aspect, external front end system  103  may comprise interfaces (e.g., server-to-server, database-to-database, or other network connections) connected to one or more of these systems. 
     An illustrative set of steps, illustrated by  FIGS. 1B, 1C, 1D, and 1E , will help to describe some operations of external front end system  103 . External front end system  103  may receive information from systems or devices in system  100  for presentation and/or display. For example, external front end system  103  may host or provide one or more web pages, including a Search Result Page (SRP) (e.g.,  FIG. 1B ), a Single Detail Page (SDP) (e.g.,  FIG. 1C ), a Cart page (e.g.,  FIG. 1D ), or an Order page (e.g.,  FIG. 1E ). A user device (e.g., using mobile device  102 A or computer  102 B) may navigate to external front end system  103  and request a search by entering information into a search box. External front end system  103  may request information from one or more systems in system  100 . For example, external front end system  103  may request information from FO System  113  that satisfies the search request. External front end system  103  may also request and receive (from FO System  113 ) a Promised Delivery Date or “PDD” for each product included in the search results. The PDD, in some embodiments, may represent an estimate of when a package containing the product will arrive at the user&#39;s desired location or a date by which the product is promised to be delivered at the user&#39;s desired location if ordered within a particular period of time, for example, by the end of the day (11:59 PM). (PDD is discussed further below with respect to FO System  113 .) 
     External front end system  103  may prepare an SRP (e.g.,  FIG. 1B ) based on the information. The SRP may include information that satisfies the search request. For example, this may include pictures of products that satisfy the search request. The SRP may also include respective prices for each product, or information relating to enhanced delivery options for each product, PDD, weight, size, offers, discounts, or the like. External front end system  103  may send the SRP to the requesting user device (e.g., via a network). 
     A user device may then select a product from the SRP, e.g., by clicking or tapping a user interface, or using another input device, to select a product represented on the SRP. The user device may formulate a request for information on the selected product and send it to external front end system  103 . In response, external front end system  103  may request information related to the selected product. For example, the information may include additional information beyond that presented for a product on the respective SRP. This could include, for example, shelf life, country of origin, weight, size, number of items in package, handling instructions, or other information about the product. The information could also include recommendations for similar products (based on, for example, big data and/or machine learning analysis of customers who bought this product and at least one other product), answers to frequently asked questions, reviews from customers, manufacturer information, pictures, or the like. 
     External front end system  103  may prepare an SDP (Single Detail Page) (e.g.,  FIG. 1C ) based on the received product information. The SDP may also include other interactive elements such as a “Buy Now” button, a “Add to Cart” button, a quantity field, a picture of the item, or the like. The SDP may further include a list of sellers that offer the product. The list may be ordered based on the price each seller offers such that the seller that offers to sell the product at the lowest price may be listed at the top. The list may also be ordered based on the seller ranking such that the highest ranked seller may be listed at the top. The seller ranking may be formulated based on multiple factors, including, for example, the seller&#39;s past track record of meeting a promised PDD. External front end system  103  may deliver the SDP to the requesting user device (e.g., via a network). 
     The requesting user device may receive the SDP which lists the product information. Upon receiving the SDP, the user device may then interact with the SDP. For example, a user of the requesting user device may click or otherwise interact with a “Place in Cart” button on the SDP. This adds the product to a shopping cart associated with the user. The user device may transmit this request to add the product to the shopping cart to external front end system  103 . 
     External front end system  103  may generate a Cart page (e.g.,  FIG. 1D ). The Cart page, in some embodiments, lists the products that the user has added to a virtual “shopping cart.” A user device may request the Cart page by clicking on or otherwise interacting with an icon on the SRP, SDP, or other pages. The Cart page may, in some embodiments, list all products that the user has added to the shopping cart, as well as information about the products in the cart such as a quantity of each product, a price for each product per item, a price for each product based on an associated quantity, information regarding PDD, a delivery method, a shipping cost, user interface elements for modifying the products in the shopping cart (e.g., deletion or modification of a quantity), options for ordering other product or setting up periodic delivery of products, options for setting up interest payments, user interface elements for proceeding to purchase, or the like. A user at a user device may click on or otherwise interact with a user interface element (e.g., a button that reads “Buy Now”) to initiate the purchase of the product in the shopping cart. Upon doing so, the user device may transmit this request to initiate the purchase to external front end system  103 . 
     External front end system  103  may generate an Order page (e.g.,  FIG. 1E ) in response to receiving the request to initiate a purchase. The Order page, in some embodiments, re-lists the items from the shopping cart and requests input of payment and shipping information. For example, the Order page may include a section requesting information about the purchaser of the items in the shopping cart (e.g., name, address, e-mail address, phone number), information about the recipient (e.g., name, address, phone number, delivery information), shipping information (e.g., speed/method of delivery and/or pickup), payment information (e.g., credit card, bank transfer, check, stored credit), user interface elements to request a cash receipt (e.g., for tax purposes), or the like. External front end system  103  may send the Order page to the user device. 
     The user device may enter information on the Order page and click or otherwise interact with a user interface element that sends the information to external front end system  103 . From there, external front end system  103  may send the information to different systems in system  100  to enable the creation and processing of a new order with the products in the shopping cart. 
     In some embodiments, external front end system  103  may be further configured to enable sellers to transmit and receive information relating to orders. 
     Internal front end system  105 , in some embodiments, may be implemented as a computer system that enables internal users (e.g., employees of an organization that owns, operates, or leases system  100 ) to interact with one or more systems in system  100 . For example, in embodiments where network  101  enables the presentation of systems to enable users to place an order for an item, internal front end system  105  may be implemented as a web server that enables internal users to view diagnostic and statistical information about orders, modify item information, or review statistics relating to orders. For example, internal front end system  105  may be implemented as a computer or computers running software such as the Apache HTTP Server, Microsoft Internet Information Services (IIS), NGINX, or the like. In other embodiments, internal front end system  105  may run custom web server software designed to receive and process requests from systems or devices depicted in system  100  (as well as other devices not depicted), acquire information from databases and other data stores based on those requests, and provide responses to the received requests based on acquired information. 
     In some embodiments, internal front end system  105  may include one or more of a web caching system, a database, a search system, a payment system, an analytics system, an order monitoring system, or the like. In one aspect, internal front end system  105  may comprise one or more of these systems, while in another aspect, internal front end system  105  may comprise interfaces (e.g., server-to-server, database-to-database, or other network connections) connected to one or more of these systems. 
     Transportation system  107 , in some embodiments, may be implemented as a computer system that enables communication between systems or devices in system  100  and mobile devices  107 A- 107 C. Transportation system  107 , in some embodiments, may receive information from one or more mobile devices  107 A- 107 C (e.g., mobile phones, smart phones, PDAs, or the like). For example, in some embodiments, mobile devices  107 A- 107 C may comprise devices operated by delivery workers. The delivery workers, who may be permanent, temporary, or shift employees, may utilize mobile devices  107 A- 107 C to effect delivery of packages containing the products ordered by users. For example, to deliver a package, the delivery worker may receive a notification on a mobile device indicating which package to deliver and where to deliver it. Upon arriving at the delivery location, the delivery worker may locate the package (e.g., in the back of a truck or in a crate of packages), scan or otherwise capture data associated with an identifier on the package (e.g., a barcode, an image, a text string, an RFID tag, or the like) using the mobile device, and deliver the package (e.g., by leaving it at a front door, leaving it with a security guard, handing it to the recipient, or the like). In some embodiments, the delivery worker may capture photo(s) of the package and/or may obtain a signature using the mobile device. The mobile device may send information to transportation system  107  including information about the delivery, including, for example, time, date, GPS location, photo(s), an identifier associated with the delivery worker, an identifier associated with the mobile device, or the like. Transportation system  107  may store this information in a database (not pictured) for access by other systems in system  100 . Transportation system  107  may, in some embodiments, use this information to prepare and send tracking data to other systems indicating the location of a particular package. 
     In some embodiments, certain users may use one kind of mobile device (e.g., permanent workers may use a specialized PDA with custom hardware such as a barcode scanner, stylus, and other devices) while other users may use other kinds of mobile devices (e.g., temporary or shift workers may utilize off-the-shelf mobile phones and/or smartphones). 
     In some embodiments, transportation system  107  may associate a user with each device. For example, transportation system  107  may store an association between a user (represented by, e.g., a user identifier, an employee identifier, or a phone number) and a mobile device (represented by, e.g., an International Mobile Equipment Identity (IMEI), an International Mobile Subscription Identifier (IMSI), a phone number, a Universal Unique Identifier (UUID), or a Globally Unique Identifier (GUID)). Transportation system  107  may use this association in conjunction with data received on deliveries to analyze data stored in the database in order to determine, among other things, a location of the worker, an efficiency of the worker, or a speed of the worker. 
     Seller portal  109 , in some embodiments, may be implemented as a computer system that enables sellers or other external entities to electronically communicate with one or more systems in system  100 . For example, a seller may utilize a computer system (not pictured) to upload or provide product information, order information, contact information, or the like, for products that the seller wishes to sell through system  100  using seller portal  109 . 
     Shipment and order tracking system  111 , in some embodiments, may be implemented as a computer system that receives, stores, and forwards information regarding the location of packages containing products ordered by customers (e.g., by a user using devices  102 A- 102 B). In some embodiments, shipment and order tracking system  111  may request or store information from web servers (not pictured) operated by shipping companies that deliver packages ordered by customers. 
     In some embodiments, shipment and order tracking system  111  may request and store information from systems depicted in system  100 . For example, shipment and order tracking system  111  may request information from transportation system  107 . As discussed above, transportation system  107  may receive information from one or more mobile devices  107 A- 107 C (e.g., mobile phones, smart phones, PDAs, or the like) that are associated with one or more of a user (e.g., a delivery worker) or a vehicle (e.g., a delivery truck). In some embodiments, shipment and order tracking system  111  may also request information from workforce management system (WMS)  119  to determine the location of individual products inside of a fulfillment center (e.g., fulfillment center  200 ). Shipment and order tracking system  111  may request data from one or more of transportation system  107  or WMS  119 , process it, and present it to a device (e.g., user devices  102 A and  102 B) upon request. 
     Fulfillment optimization (FO) system  113 , in some embodiments, may be implemented as a computer system that stores information for customer orders from other systems (e.g., external front end system  103  and/or shipment and order tracking system  111 ). FO system  113  may also store information describing where particular items are held or stored. For example, certain items may be stored only in one fulfillment center, while certain other items may be stored in multiple fulfillment centers. In still other embodiments, certain fulfillment centers may be designed to store only a particular set of items (e.g., fresh produce or frozen products). FO system  113  stores this information as well as associated information (e.g., quantity, size, date of receipt, expiration date, etc.). 
     FO system  113  may also calculate a corresponding PDD (promised delivery date) for each product. The PDD, in some embodiments, may be based on one or more factors. For example, FO system  113  may calculate a PDD for a product based on a past demand for a product (e.g., how many times that product was ordered during a period of time), an expected demand for a product (e.g., how many customers are forecast to order the product during an upcoming period of time), a network-wide past demand indicating how many products were ordered during a period of time, a network-wide expected demand indicating how many products are expected to be ordered during an upcoming period of time, one or more counts of the product stored in each fulfillment center  200 , which fulfillment center stores each product, expected or current orders for that product, or the like. 
     In some embodiments, FO system  113  may determine a PDD for each product on a periodic basis (e.g., hourly) and store it in a database for retrieval or sending to other systems (e.g., external front end system  103 , SAT system  101 , shipment and order tracking system  111 ). In other embodiments, FO system  113  may receive electronic requests from one or more systems (e.g., external front end system  103 , SAT system  101 , shipment and order tracking system  111 ) and calculate the PDD on demand. 
     Fulfillment messaging gateway (FMG)  115 , in some embodiments, may be implemented as a computer system that receives a request or response in one format or protocol from one or more systems in system  100 , such as FO system  113 , converts it to another format or protocol, and forward it in the converted format or protocol to other systems, such as WMS  119  or 3 rd  party fulfillment systems  121 A,  121 B, or  121 C, and vice versa. 
     Supply chain management (SCM) system  117 , in some embodiments, may be implemented as a computer system that performs forecasting functions. For example, SCM system  117  may forecast a level of demand for a particular product based on, for example, based on a past demand for products, an expected demand for a product, a network-wide past demand, a network-wide expected demand, a count products stored in each fulfillment center  200 , expected or current orders for each product, or the like. In response to this forecasted level and the amount of each product across all fulfillment centers, SCM system  117  may generate one or more purchase orders to purchase and stock a sufficient quantity to satisfy the expected forecasted demand for a particular product. 
     Workforce management system (WMS)  119 , in some embodiments, may be implemented as a computer system that monitors workflow. For example, WMS  119  may receive event data from individual devices (e.g., devices  107 A- 107 C or  119 A- 119 C) indicating discrete events. For example, WMS  119  may receive event data indicating the use of one of these devices to scan a package. As discussed below with respect to fulfillment center  200  and  FIG. 2 , during the fulfillment process, a package identifier (e.g., a barcode or RFID tag data) may be scanned or read by machines at particular stages (e.g., automated or handheld barcode scanners, RFID readers, high-speed cameras, devices such as tablet  119 A, mobile device/PDA  1196 , computer  119 C, or the like). WMS  119  may store each event indicating a scan or a read of a package identifier in a corresponding database (not pictured) along with the package identifier, a time, date, location, user identifier, or other information, and may provide this information to other systems (e.g., shipment and order tracking system  111 ). 
     WMS  119 , in some embodiments, may store information associating one or more devices (e.g., devices  107 A- 107 C or  119 A- 119 C) with one or more users associated with system  100 . For example, in some situations, a user (such as a part- or full-time employee) may be associated with a mobile device in that the user owns the mobile device (e.g., the mobile device is a smartphone). In other situations, a user may be associated with a mobile device in that the user is temporarily in custody of the mobile device (e.g., the user checked the mobile device out at the start of the day, will use it during the day, and will return it at the end of the day). 
     WMS  119 , in some embodiments, may maintain a work log for each user associated with system  100 . For example, WMS  119  may store information associated with each employee, including any assigned processes (e.g., unloading trucks, picking items from a pick zone, rebin wall work, packing items), a user identifier, a location (e.g., a floor or zone in a fulfillment center  200 ), a number of units moved through the system by the employee (e.g., number of items picked, number of items packed), an identifier associated with a device (e.g., devices  119 A- 119 C), or the like. In some embodiments, WMS  119  may receive check-in and check-out information from a timekeeping system, such as a timekeeping system operated on a device  119 A- 119 C. This activity information may be used to track a user&#39;s productivity. 
     3 rd  party fulfillment (3PL) systems  121 A- 121 C, in some embodiments, represent computer systems associated with third-party providers of logistics and products. For example, while some products are stored in fulfillment center  200  (as discussed below with respect to  FIG. 2 ), other products may be stored off-site, may be produced on demand, or may be otherwise unavailable for storage in fulfillment center  200 . 3PL systems  121 A- 121 C may be configured to receive orders from FO system  113  (e.g., through FMG  115 ) and may provide products and/or services (e.g., delivery or installation) to customers directly. In some embodiments, one or more 3PL systems  121 A- 121 C may be part of system  100 , while in other embodiments, one or more of 3PL systems  121 A- 121 C may be outside of system  100  (e.g., owned or operate by a third-party provider). 
     Fulfillment Center Auth system (FC Auth)  123 , in some embodiments, may be implemented as a computer system with a variety of functions. For example, in some embodiments, FC Auth  123  may act as a single-sign on (SSO) service for one or more other systems in system  100 . For example, FC Auth  123  may enable a user to log in via internal front end system  105 , determine that the user has similar privileges to access resources at shipment and order tracking system  111 , and enable the user to access those privileges without requiring a second log in process. FC Auth  123 , in other embodiments, may enable users (e.g., employees) to associate themselves with a particular task. For example, some employees may not have an electronic device (such as devices  119 A- 119 C) and may instead move from task to task, and zone to zone, within a fulfillment center  200 , during the course of a day. FC Auth  123  may be configured to enable those employees to indicate what task they are performing and what zone they are in at different times of day. 
     Labor management system (LMS)  125 , in some embodiments, may be implemented as a computer system that stores attendance and overtime information for employees (including full-time and part-time employees). For example, LMS  125  may receive information from FC Auth  123 , WMS  119 , devices  119 A- 119 C, transportation system  107 , and/or devices  107 A- 107 C. 
     The particular configuration depicted in  FIG. 1A  is an example only. For example, while  FIG. 1A  depicts FC Auth system  123  connected to FO system  113 , not all embodiments require this particular configuration. Indeed, in some embodiments, the systems in system  100  may be connected to one another through one or more public or private networks, including the Internet, an Intranet, a WAN (Wide-Area Network), a MAN (Metropolitan-Area Network), a wireless network compliant with the IEEE 802.11a/b/g/n Standards, a leased line, or the like. In some embodiments, one or more of the systems in system  100  may be implemented as one or more virtual servers implemented at a data center, server farm, or the like. 
       FIG. 2  depicts a fulfillment center  200 . Fulfillment center  200  is an example of a physical location that stores items for shipping to customers when ordered. Fulfillment center (FC)  200  may be divided into multiple zones, each of which are depicted in  FIG. 2 . These “zones,” in some embodiments, may be thought of as virtual divisions between different stages of a process of receiving items, storing the items, retrieving the items, and shipping the items. So while the “zones” are depicted in  FIG. 2 , other divisions of zones are possible, and the zones in  FIG. 2  may be omitted, duplicated, or modified in some embodiments. 
     Inbound zone  203  represents an area of FC  200  where items are received from sellers who wish to sell products using system  100  from  FIG. 1A . For example, a seller may deliver items  202 A and  202 B using truck  201 . Item  202 A may represent a single item large enough to occupy its own shipping pallet, while item  202 B may represent a set of items that are stacked together on the same pallet to save space. 
     A worker will receive the items in inbound zone  203  and may optionally check the items for damage and correctness using a computer system (not pictured). For example, the worker may use a computer system to compare the quantity of items  202 A and  202 B to an ordered quantity of items. If the quantity does not match, that worker may refuse one or more of items  202 A or  202 B. If the quantity does match, the worker may move those items (using, e.g., a dolly, a handtruck, a forklift, or manually) to buffer zone  205 . Buffer zone  205  may be a temporary storage area for items that are not currently needed in the picking zone, for example, because there is a high enough quantity of that item in the picking zone to satisfy forecasted demand. In some embodiments, forklifts  206  operate to move items around buffer zone  205  and between inbound zone  203  and drop zone  207 . If there is a need for items  202 A or  202 B in the picking zone (e.g., because of forecasted demand), a forklift may move items  202 A or  202 B to drop zone  207 . 
     Drop zone  207  may be an area of FC  200  that stores items before they are moved to picking zone  209 . A worker assigned to the picking task (a “picker”) may approach items  202 A and  202 B in the picking zone, scan a barcode for the picking zone, and scan barcodes associated with items  202 A and  202 B using a mobile device (e.g., device  119 B). The picker may then take the item to picking zone  209  (e.g., by placing it on a cart or carrying it). 
     Picking zone  209  may be an area of FC  200  where items  208  are stored on storage units  210 . In some embodiments, storage units  210  may comprise one or more of physical shelving, bookshelves, boxes, totes, refrigerators, freezers, cold stores, or the like. In some embodiments, picking zone  209  may be organized into multiple floors. In some embodiments, workers or machines may move items into picking zone  209  in multiple ways, including, for example, a forklift, an elevator, a conveyor belt, a cart, a handtruck, a dolly, an automated robot or device, or manually. For example, a picker may place items  202 A and  202 B on a handtruck or cart in drop zone  207  and walk items  202 A and  202 B to picking zone  209 . 
     A picker may receive an instruction to place (or “stow”) the items in particular spots in picking zone  209 , such as a particular space on a storage unit  210 . For example, a picker may scan item  202 A using a mobile device (e.g., device  119 B). The device may indicate where the picker should stow item  202 A, for example, using a system that indicates an aisle, shelf, and location. The device may then prompt the picker to scan a barcode at that location before stowing item  202 A in that location. The device may send (e.g., via a wireless network) data to a computer system such as WMS  119  in  FIG. 1A  indicating that item  202 A has been stowed at the location by the user using device  1196 . 
     Once a user places an order, a picker may receive an instruction on device  119 B to retrieve one or more items  208  from storage unit  210 . The picker may retrieve item  208 , scan a barcode on item  208 , and place it on transport mechanism  214 . While transport mechanism  214  is represented as a slide, in some embodiments, transport mechanism may be implemented as one or more of a conveyor belt, an elevator, a cart, a forklift, a handtruck, a dolly, a cart, or the like. Item  208  may then arrive at packing zone  211 . 
     Packing zone  211  may be an area of FC  200  where items are received from picking zone  209  and packed into boxes or bags for eventual shipping to customers. In packing zone  211 , a worker assigned to receiving items (a “rebin worker”) will receive item  208  from picking zone  209  and determine what order it corresponds to. For example, the rebin worker may use a device, such as computer  119 C, to scan a barcode on item  208 . Computer  119 C may indicate visually which order item  208  is associated with. This may include, for example, a space or “cell” on a wall  216  that corresponds to an order. Once the order is complete (e.g., because the cell contains all items for the order), the rebin worker may indicate to a packing worker (or “packer”) that the order is complete. The packer may retrieve the items from the cell and place them in a box or bag for shipping. The packer may then send the box or bag to a hub zone  213 , e.g., via forklift, cart, dolly, handtruck, conveyor belt, manually, or otherwise. 
     Hub zone  213  may be an area of FC  200  that receives all boxes or bags (“packages”) from packing zone  211 . Workers and/or machines in hub zone  213  may retrieve package  218  and determine which portion of a delivery area each package is intended to go to, and route the package to an appropriate camp zone  215 . For example, if the delivery area has two smaller sub-areas, packages will go to one of two camp zones  215 . In some embodiments, a worker or machine may scan a package (e.g., using one of devices  119 A- 119 C) to determine its eventual destination. Routing the package to camp zone  215  may comprise, for example, determining a portion of a geographical area that the package is destined for (e.g., based on a postal code) and determining a camp zone  215  associated with the portion of the geographical area. 
     Camp zone  215 , in some embodiments, may comprise one or more buildings, one or more physical spaces, or one or more areas, where packages are received from hub zone  213  for sorting into routes and/or sub-routes. In some embodiments, camp zone  215  is physically separate from FC  200  while in other embodiments camp zone  215  may form a part of FC  200 . 
     Workers and/or machines in camp zone  215  may determine which route and/or sub-route a package  220  should be associated with, for example, based on a comparison of the destination to an existing route and/or sub-route, a calculation of workload for each route and/or sub-route, the time of day, a shipping method, the cost to ship the package  220 , a PDD associated with the items in package  220 , or the like. In some embodiments, a worker or machine may scan a package (e.g., using one of devices  119 A- 119 C) to determine its eventual destination. Once package  220  is assigned to a particular route and/or sub-route, a worker and/or machine may move package  220  to be shipped. In exemplary  FIG. 2 , camp zone  215  includes a truck  222 , a car  226 , and delivery workers  224 A and  224 B. In some embodiments, truck  222  may be driven by delivery worker  224 A, where delivery worker  224 A is a full-time employee that delivers packages for FC  200  and truck  222  is owned, leased, or operated by the same company that owns, leases, or operates FC  200 . In some embodiments, car  226  may be driven by delivery worker  224 B, where delivery worker  224 B is a “flex” or occasional worker that is delivering on an as-needed basis (e.g., seasonally). Car  226  may be owned, leased, or operated by delivery worker  224 B. 
       FIG. 3A  is a flowchart illustrating steps of an exemplary log in and log out process  300  that may be performed by a processor in accordance with the disclosed embodiments. For example, process  300  may be performed entirely or in part on a computing device such as a smart phone or PDA (e.g., devices  119 A- 119 C in  FIG. 1 ).  FIG. 8  described below, is an example of such a device that may perform the process using processor  802 . While process  300  is described with respect to computing device  800 , one of skill will understand that other devices may implement process  300 . One of skill will further understand that the steps illustrated in  FIG. 3A  are exemplary and steps may be added, duplicated, modified, or deleted in some embodiments. 
     At step  301 , processor  802  determines a location of the mobile devices  119 A- 119 C. Processor  802  may utilize several forms of information available through the mobile device to determine the location of the mobile devices  119 A- 119 C. For example, the location may be determined by the mobile devices  119 A- 119 C connecting to a wireless network associated with a location, GPS data, or any other form of location data known in the art. 
     At step  302 , processor  802  instructs computing device  800  to display a first user interface element that executes a start option that allows the user to indicate that the user is beginning work (e.g., on a display). In some embodiments, computing device  800  will only display the start option when it determines that computing device  800  is within an accepted location, such as the location of a warehouse, fulfillment center, office, or other place associated with an employer. 
     In another embodiment, the processor  802  will only instruct the computing device  800  to display the start option when the user accesses the processor at an accepted time to start working according to the user&#39;s work schedule. In some embodiments, a memory device of computing device  800  (e.g., memory  804 ) may store the user&#39;s work schedule, in other embodiments the WMS  119  and/or LMS  125  may store the user&#39;s work schedule, and in other embodiments, any other system within the system  100  may store the user&#39;s work schedule and synchronize the stored information with other systems in system  100 . The user&#39;s work schedule may include the user&#39;s shift schedule, the employer&#39;s needed capacity for workers, the user&#39;s vacation schedule, or any other information that determines when the user is allowed to work. When the user&#39;s work schedule is stored in a system, such as WMS  119 , the processor  802  may receive the user&#39;s schedule from the WMS  119 . For example, processor  802  may query the WMS  119  to determine whether the user is allowed to work at that time, receive the user&#39;s full work schedule, or perform any other action that informs the processor  802  whether the user may start working. 
     In another embodiment, the computing device  800  may only display the start option if the user has not worked too many hours in a time frame. In this example, the computing device may either access the memory  804 , WMS  119 , or LMS  125  to receive the number of hours the user has worked. If the user has worked more than a maximum number of hours for a time frame, the computing device  800  will not display the start option. Alternatively, the computing device  800  may not display the start option if the user has worked more hours than any limit set by the employer. Another alternative allows the computing device  800  to receive a command from the WMS  119  or LMS  125  to not display the start option. This command from the WMS  119  or LMS  125  may be based on the WMS  119  performing the above analysis or any other reason set within the WMS  119  or LMS  125 . 
     At step  303 , the computing device  800  receives an input from the user indicating that the user selected the start option. In some embodiments, this input may contain the information that the user has started work at the time when the start option was selected. In other embodiments, the user may provide the input through a user interface. In other embodiments, the input may include additional data such as the jobs worked, tasks the user will perform, hours worked, anticipated number of hours, location, locations worked, productivity information, and any other information the employer may want to receive. Computing device  800  may record the time the user started work, for example, in a database or file on computing device  800 . 
     In some embodiments, the computing device  800  may collect this data by asking questions before or after the user selects the start option. These questions may ask for yes/no answers, choices between options or categories, open entries, or any other type of question the employer wishes to ask. In other embodiments, the computing device  800  may collect this data from the user&#39;s work schedule if the data is contained therein. The computing device  800  may also ask a series of questions based on the answer(s) to or category selected in the previous question(s). The computing device  800  then receives the answer selected. 
     In some embodiments, the computing device  800  may also send the data collected to the WMS  119  and/or LMS  125 . The computing device  800  may send this information after receiving the information in the input, based on scheduled updates, or in real time as the processor  802  receives information. The computing device  800  may send this as information stored in HTTP requests, as flags in HTTP requests, as part of a social networking message, or another protocol known in the art. 
     At step  304 , the computing device  800  displays a second user interface element that executes an end option that allows the user to indicate that the user is ending work. 
     At step  305 , the computing device  800  receives an input from the user that the user selected the end option. In some embodiments, this input may contain the information that the user has stopped work at the time when the end option was selected. In other embodiments, the input may include additional data such as the jobs worked, tasks the user performed, hours worked, anticipated number of hours, location, locations worked, productivity information, and any other information the employer may want to receive. Computing device  800  may record the time the user ended work, for example, in a database or file on computing device  800 . 
     In some embodiments, the computing device  800  may collect this data by asking questions before or after the user selects the end option. The computing device  800  may ask these questions through a user interface, which allows the user to enter answers through radio buttons, buttons, voice interaction, alphanumeric input, or other methods known in the art. These questions may ask for yes/no answers, choices between options, open entries, or any other type of question the employer wishes to ask. In other embodiments, the computing device  800  may collect this data from the user&#39;s work schedule if the data is contained therein. 
     In some embodiments, the computing device  800  may also send the data collected (e.g., start time, end time) to the WMS  119  and/or LMS  125 . The computing device  800  may send this information after receiving the information in the input, based on scheduled updates, or in real time as the processor receives information. 
     In some embodiments, the computing device  800  may also receive data from the WMS  119  or LMS  125 . This data and information may include the number of hours a user has worked, the maximum number of hours a user can work, the user&#39;s accepted time, the user&#39;s accepted locations, a report compiling and analyzing data about the user, or other information and data. 
     In some embodiments, the computing device  800  may also execute instructions to automatically warn or log out a user if the computing device  800  detects certain conditions. For example, the user may be logged out if the user leaves an accepted location. Another example may be that the computing device  800  may issue a warning to the user if the number of hours the user has worked when the user exceeds a preset number of hours for a time frame. These warnings may be intended to prevent the user from working more than the maximum number of accepted hours. In some embodiments, the computing device  800  may issue the warning when a threshold number of hours that is less than the maximum number of hours is met. This warning informs the user that they are approaching the maximum number of hours. The computing device  800  may also or alternatively be programmed to issue the warning when the user reaches the maximum number of hours, informing the user to log out and stop working. 
     In another embodiment, the computing device  800  may automatically execute the end option and log out the user upon detecting that a user exceeds the maximum number of hours. The computing device  800  may also query the WMS  119  and/or LMS  125  for data or instructions on how to proceed. 
     In some embodiments, the computing device  800  may keep track of the hours worked by the hours worked by the user, for example by storing the information in memory  804 . However, the WMS  119  or LMS  125  may also track the user&#39;s hours, and the computing device  800  may query the WMS  119  or LMS  125  to receive the number of hours worked, instructions to issue a warning as described, or instructions to execute the end option and log out the user. 
     In some embodiments, the computing device  800  may also query the WMS  119  or LMS  125  to determine whether the user has been active, i.e., whether the user is actually working. In some cases, users may forget to log out when they leave or otherwise not log out. This functionality allows the employer to ensure the user is actively working while the user is logged in. To accomplish this, the computing device  800  may query the WMS  119  or LMS  125 . The WMS  119  or LMS  125  either contains the activity information necessary to make the determination or can in turn query other systems to receive activity information necessary to make the determination. As described earlier, activity information to determine whether a user is actively working may include whether the user has moved any items through the system, is logged into any part of the system  100 , or any other activity information. 
     After receiving the activity information, the WMS  119  or LMS  125  may either analyze the data to determine whether the user is actively working or send the data to the computing device  800 , where the computing device receives the activity information and analyzes the activity information to determine whether the user is actively working. 
     If the computing device, WMS  119 , or LMS  125  determines that the user is not actively working, the processor  802  can be instructed to execute the end option and log out the user. 
     In some embodiments, the computing device  800  may use a token to determine whether the user has been active. When a user selects a start option, the computing device  800 , WMS  119 , or LMS  125  issues a token. Whenever the user uses any part of the system  100 , that part of the system will use the token to authenticate the user. Tokens may identify a login session or user identity, and may include data in a variety of forms, including numbers, letters, or the like. In some embodiments, tokens may also be cryptographic. For example, if the user scans a package identifier and when moving a unit to a different location, the scanning device may use the token to access WMS  119  or LMS  125  to send the event data as discussed above. The computing device  800  can execute instructions to query the WMS  119  or LMS  125  for information indicating whether the token has been used within a time frame, for example two days. If the information indicates the token has not been used, then the computing device  800  executes the end option to log out the user. 
       FIGS. 3B-E  illustrate an exemplary interface for a program executed by the computing device. The description of these figures serves to explain the functionality of the program. This program may be executed on any device accessible to the user, for example mobile devices  119 A- 119 C. The program may be accessed as a webpage using a link, QR code, or web address, it may be a program downloaded to a memory device of the computing device, or any other form of accessing the program known in the art. While the descriptions of  FIGS. 3A-D  describe features within the interface, some features may be omitted and other features may be added based on the specific implementation for the program. 
       FIG. 3B  illustrates an exemplary task-selection screen  310 . In some embodiments, task-selection screen  310  may include one or more blocks  312 ,  314 , and  316 .

     In step  450 , computing device  800  may receive analytical data from the WMS  119  or LMS  125 . This analytical data can be information regarding how many hours the user has worked, whether the user has or is about to exceed the maximum number of hours allowed, whether the user has worked within a time frame, productivity information or any other analytical data discussed herein. 
     In step  480 , computing device  800  may send data contained within the input with the end option to the WMS  119  and/or LMS  125 . Similar to step  440 , the computing device  800  may send this information after receiving the information in the input, based on scheduled updates, or in real time as the processor receives information. Such additional aspects of process  400  are not limiting on the process  300  above, but instead illustrate further capabilities of system  100 . 
       FIGS. 5A-E  illustrate exemplary interfaces for a program executed by a computing device, such as mobile devices  119 A- 119 C. The description of these figures serves to explain some functionality of the program. This program may be executed on any device accessible to the user. The program may be accessed as a webpage using a link, QR code, web address or the like. The program may also be downloaded to memory device  804 . In other embodiments, other forms of accessing the program known in the art may be used. While the descriptions of  FIGS. 5A-E  describe features within the interface, some features may be omitted and other features may be added based on the specific implementation for the program. 
       FIG. 5A  illustrates an exemplary log in screen  510 . Block  512  enables the user to select the job role, job location, or other preliminary information that may be needed. A block in the interface may include drop down menus, buttons, radio buttons, alphanumeric inputs, or other UI features known in the art. In some embodiments, the user may select to work in a warehouse, a fulfillment center, or other role. The program may include instructions to present specific features, options, or questions to the user based on the role selected. 
     Block  514  may be an input field receiving the user&#39;s log in credentials. For example, the input field may receive a user identification number, username, password, personal identification number, or other information known in the art for authenticating users. Block  516  may then be a submit, or “log in” option, such as a button. In another embodiment, block  516  may also include other options such as password recovery, username recovery, or other options. 
       FIG. 5B  illustrates an exemplary home screen  520  for the program. In some embodiments, block  522  may be a button to view the user&#39;s schedule or information, depict a user&#39;s schedule, show other information for the user, or the like. Button  524  may direct the computing device to initiate a vacation request. 
       FIG. 5C  illustrates an exemplary screen  530  in a vacation request.  FIG. 5C  depicts two different sections of the same screen (e.g., a top portion and a bottom portion), which a user may have to scroll through the window to view.  FIG. 5C  may display a form for the user to input information for the vacation request, including block  531 , which displays the type of vacation requested. Block  531  could be represented as a drop-down menu, a series of radio buttons, an alphanumeric input, or any other known form of information selection.  FIG. 5C  further includes block  532  for the user to enter a start date for the vacation request, block  533  for the user to enter an end date for the vacation request, block  534  for the user to enter a description of the vacation request, and button  535  to submit the vacation request. 
     In some embodiments, block  534  may include an alphanumeric entry for the user to enter a description of the vacation request, option of types of vacations the user may select, or other forms of input for the user to provide a description of the vacation request. 
     In other embodiments, block  534  may include an option to provide proof of the vacation. In this embodiment, some employers may require proof that a vacation was taken for a particular purpose, such as a doctor&#39;s visit or jury duty. When the type of vacation will have evidence beforehand, such as a summons for jury duty, the employer may require the user to upload that evidence to be included in the vacation request. Similarly, this information may not be available until a later time, such as a doctor&#39;s note after the doctor&#39;s appointment has occurred. The program may also provide users an option to submit this evidence at a later time. The user may input this evidence, for example, by taking a picture from within the program, or by uploading a file with the required proof included. 
       FIG. 5D  illustrates an exemplary screen  540  for the program. This screen displays a user&#39;s vacation requests and may be accessed from the screen displayed in  FIG. 5B  or any other screen. On this screen, blocks  541  and  542  represent two different vacation requests. The screen  5 D may contain as many blocks as there are vacation requests, including no blocks when there are no vacation requests. Block  542  shows an example vacation request. This request includes a progress bar  543  and a delete button  544 . 
     In some embodiments, progress bar  543  may include a set of notes, and the nodes are colored in as their represented tasks are completed. In the present embodiment, progress bar  543  includes three nodes. The first node may represent a completed vacation request as discussed for  FIG. 5C . The second node may represent a manager has approved the application. Additional nodes may be added as well. For example, as illustrated by progress bar  545 , there may be a third node, which may represent a second manager&#39;s approval, that evidence has been uploaded, or other criteria to complete a vacation request. The evidence example may be used when a user has requested a vacation that requires evidence that is not attainable until after the vacation has been taken, such as a doctor&#39;s note certifying that the doctor&#39;s appointment was taken as discussed earlier. 
     Delete button  544  may allow a user to delete a vacation request. In some embodiments, this option may only be available until the vacation has been approved, but other embodiments may allow the user to delete the vacation request later, such as any time before the vacation actually occurs. Selecting delete button  544  may also cause the computing device to produce a confirmation message or screen for the user to confirm that they would like to delete the vacation request. 
       FIG. 6  illustrates a manager&#39;s portal  600  through which a manager may manage vacation and other scheduling requests. In some embodiments, the manager&#39;s portal  600  may be accessible through a device, such as one or more of mobile devices  119 A- 119 C using the manager&#39;s log in credentials. Other embodiments may only allow the manger&#39;s portal  600  to be accessed through internal front end system  105 . 
     Manager&#39;s portal  600  may include table  602  and search options  606 . Table  602  represents a table of vacation requests where each row is a vacation request and each column is information or options related to the vacation request. Exemplary information may include the identification information for the user that submitted their vacation request, such as the user&#39;s name, user ID, employment type, group, and other information the manager may want to see. 
     In some embodiments, table  602  may also include a column with delete button  604  available for each request. Delete button  604  may be displayed only until the vacation request is approved, or after the vacation request is approved. Selecting delete button  604  may also cause the computing device to display a confirmation option or confirmation screen. 
     In some embodiments, table  602  may also include a report button  608  for each vacation request. Report button  608  generates, or retrieves from memory, a report on the user that submitted the vacation request. This report can include any information the manager may find useful for approving a vacation request, such as hours worked, vacations previously taken, the group the employee works for, the evidence provided, and other information. 
     In some embodiments, table  602  may also include box  609  for each vacation request. Box  609  may include an approve/deny option for the vacation request, or it may provide an option to assign a reviewer to the vacation request for approval. The option to assign a review may be embodied as a drop-down menu, a series of buttons, a series of radio buttons, alphanumeric input, or other inputs known in the art. 
       FIG. 7  illustrates an exemplary database table  700  of vacations that users can schedule. In some embodiments, the database table  700  may include columns such as vacation category column  702 , vacation type column  704 , employee eligibility column  706 , requirements column  708 , maximum number of days column  710 , evidence requirement column  712 , and extra approval requirement column  714 . Database table  700  may include more or fewer columns depending on the employer&#39;s requirements for determining whether a user is eligible for a vacation and the requirements for approval. 
     In some embodiments, the types of vacations may be divided into categories, such as those in vacation category column  702 , which includes special vacation and regular vacation categories. The types of vacations in vacation type column  704  can be sorted into these categories, as shown in  FIG. 7 . The special vacation category may signify events that do not happen frequently, such as paternity leave, weddings, and family deaths. The regular vacation category may signify types of vacation that occur on a regular basis, such as Paid Time Off (PTO), doctor&#39;s visits, or mandatory military service for countries that require citizens to perform certain military duties every year. In some embodiments, designating a vacation as a special vacation may obligate a user to meet an additional set of requirements beyond the typical requirements, such as requiring an additional manager to approve the vacation, requiring a specific person to approve, or any other requirement. 
     In some embodiments, employee eligibility column  706  can signify which employees can be eligible for a type of vacation. Employees may be divided into categories based on any criteria set by the employer, such as full-time employees, contractors, fulfillment center employees, warehouse employees, engineers, sales, managers, janitorial staff, or any other category. The table may then indicate which of the employee categories may be eligible for each type of vacation. For example, only full-time employees may qualify for paternity leave while all employees may qualify for PTO. In another embodiment, separate rows may be used for different employee categories to allow further changes in qualifications, such as the maximum number of days allowed for a type of vacation. For example, engineers may only have 10 days of PTO, but managers may have 15 days of PTO. 
     In some embodiments, the requirements column  708  may set any special requirements that may be necessary for a user to qualify for the type of vacation. For example, if a user is requesting to take paternity leave, requirement column  708  may dictate that the user must have a newborn child at home. As another example, if a user is requesting to take time for the mandatory military service, then the user must have received an official notice setting their assigned time for performing the military service. 
     In some embodiments, maximum number of days column  710  may set the maximum number of days that user may qualify for a type of vacation. In some embodiments, this number may vary for the same type of vacation depending on other columns, such as the employee eligibility column  706  as discussed herein. 
     In some embodiments, evidence requirement column  712  may dictate whether evidence is required to qualify for the type of vacation. For example, users may receive a notice that they must perform their mandatory military service, and the system may require the user to provide this notice as evidence. In some embodiments, evidence requirement column  712  may be a yes/no requirement, may specify qualifying evidence, or may set any other requirement desired by the employer. 
     In some embodiments, extra approval requirement column  714  may determine whether a type of vacation requires an additional manager to approve the vacation besides the default number of approvers. For example, special vacations may require two managers to approve the vacation whereas a regular vacation only requires one manager to approve. In some embodiments, the type of vacation may require the approval of a specific person. This may be indicated in extra approval requirement column  714 , in another column shown, or in an additional column not shown.
