     DETAILED DESCRIPTION 
       [0055]    Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. 
         [0056]    It should be noted that a plurality of hardware and software based devices, as well as a plurality of different structural components may be utilized to implement the invention. Furthermore, and as described in subsequent paragraphs, the specific configurations illustrated in the drawings are intended to exemplify embodiments of the invention and that other alternative configurations are possible. 
         [0057]    As noted above, embodiments of the present invention provide computer-implemented methods and systems for managing a workforce effectively. Embodiments may be configured separately or in a combination to reduce operational costs, manage access control, enforce organizational policies and increase efficiency of the workforce at a single or multiple locations while minimizing the elements of fraud and inaccuracy. Embodiments may also integrate with existing and allied systems, such as human resource (“HR”), payroll, customer relationship, enterprise resource planning, banking, supply chain, warehouse, asset, infrastructure, training, access control, production, administration and security management systems that overlap various components of workforce management. 
         [0058]      FIG. 1 a    illustrates a workforce management system  10  providing integrated access control. The system  10  includes a server  12  that hosts server software and related tools connected over a connection  14 , such as a TCP/IP connection, to one or more access control points  16 . An access control point  16  can be installed at a worker entrance of a building. For example, in one embodiment, one access control point  16  can be used for inward pedestrian worker traffic and another access control point  16  can be used for outward pedestrian worker traffic. Each access control point  16  includes a biometric scanning device  20  (hereinafter referred to as the “device  20 ”) and an electromagnetic/electric barrier or gate  22  (hereinafter referred to as the “turnstile  22 ”). As described in more detail below, each access control point  16  (e.g., the device  20 ) is configured to collect information about workers (e.g., time and attendance data) and control access to a particular premises according to administrative, HR, fire and security, payroll, or other policies set by management. As described in more detail below, the biometric scanning device  20  can be configured to scan one or more portions of a subject (e.g., using one or more biometric scanners). For example, the device  20  can include a left eye (iris and/or retina), right eye (iris and/or retina), and three-dimensional (“3D”) face based multi-biometric scanning device. Different combinations and/or other portions of a subject can also be scanned with the device  20  (e.g., finger prints, veins, etc.). 
         [0059]      FIG. 1 b    illustrates different types of access control points  16  with different combinations of devices  20  and turnstiles  22 . For example, a tripod turnstile  22  can be used with one device  20  for both inward and outward traffic. A tripod turnstile  22  can also be used with a separate device  20  for inward and outward traffic (see  FIG. 1 b   (A)). As illustrated in  FIG. 1 b   (B), a full height turnstile  22  can also be used with one or more devices  20  (see  FIG. 1 b   (B)). In other embodiments, a butterfly-wing-gate turnstile  22  can also be used with two passages and four devices  20  (see  FIG. 1 b   (C)) or with two passages and two devices  20  (see  FIG. 1 b   (D)). As illustrated in  FIGS. 1 b   (E) and  1   b (F), an infrared-door-type turnstile  22  or infrared-pillar-type turnstile  22  can be used with one or more devices  20 . Also, an access-control-door-lock turnstile  22  can be used with one or more devices  20  (see  FIG. 1 b   (G)). 
         [0060]      FIG. 1 c    schematically illustrates an access room  30  used as a passage for inward and outward pedestrian traffic located at an entrance to an area  31 . The room  30  can be divided in three sections. One section is assigned for inward traffic, one section is assigned for outward traffic, and one section is assigned for an office  32 . Two or more access control points  16  are installed in the room  30  (e.g., one or more in each passage). For inward traffic, a device  20  can be installed on the left side of a turnstile  22 , and, for outward traffic, a device  20  can be installed on the right side of a turnstile  22 . 
         [0061]    In some embodiments, the walls of the room  30  are constructed with opaque material, and at least a portion of the walls of the office  32  (e.g., the walls facing the access control points  16 ) are transparent or include transparent windows. The office  32  provides space for one or more officers to service queries of workers, such as through a window  34 , installed on each side of the office  32  (e.g., to cater to both inward and outward traffic). A door of the office  32  can be installed on the passage side of the outward traffic. 
         [0062]    The room  30  can include four doors. The four doors can be kept open for easy flow of pedestrian traffic in scheduled traffic times. Other doors and passages to the area  31  can be locked and not used except for emergencies. In some embodiments, personal areas, such as a cafeteria, washrooms, a locker room, a smoking area, and prayer rooms, are kept outside the area  31 . 
         [0063]    The access control points  16  in the room  30  integrate the functions of access control and workforce management. In particular, the points  16  automatically capture time, attendance, and access data, which eliminates the need for a worker to physically clock-in and clock-out, which a worker can otherwise forget to do or can do improperly. In particular, every clock-in and clock-out is captured separately by the access control points  16 , which eliminates human error associated with this process, such as buddy-punching fraud (i.e., when your “buddy” fraudulently clocks you “IN” or “OUT”). The arrangement of the points  16  in the room  30  also implements queue management, provides visibility and control to officers on duty, caters to workers&#39; access-related requests, and offers better ventilation for temperature settings associated with the system  10 . 
         [0064]      FIG. 1 d    illustrates lighting conditions for the room  30 . As illustrated in  FIG. 1 d   , opaque walls  38  in the room  30  serve as light barriers even as the sun changes positions to prevent sunlight  39  from reaching the areas where the devices  20  are installed. Therefore, the floor plan of the room  30  and the position of the opaque walls  38  efficiently control lighting conditions for the devices  20 , which is an important factor for proper functioning of the devices  20  (e.g., when performing face, iris, or retina scanning). 
         [0065]    The device  20  is configured to recognize workers through their eyes and face (e.g., 3D facial recognition) to clock-in to and clock-out of their place of employment as part of a time and attendance component of the system  10 . Therefore, workers use the devices  20  to mark their attendance and gain access to various areas. As illustrated in  FIGS. 2-3 , the device  20  includes a housing front  40  and a housing back  42 , a digital signal processing (“DSP”) board  44 , a camera board  46 , a scanner infrared illuminator board  48 , a keypad  50  (forming part of a user interface  51  of the device  20 ), a liquid crystal display (“LCD”) screen  52 , a radio frequency identification (“RFID”) antenna  54 , a speaker  56 , and a power light emitting diode (“LED”)  58 . The housing back  42  is supported by right and left exhaust window covers  42   a  and a bottom exhaust window  42   b.    
         [0066]      FIG. 4  schematically illustrates components of the device  20 . As illustrated in  FIG. 4 , and as previously illustrated in  FIGS. 2-3 , the device  20  includes the DSP board  44 , the camera board  46 , the scanner infrared illuminator board  48 , the keypad  50 , the LCD screen  52 , the RFID antenna  54 , the speaker  56 , and a power LED  58  with a AC/DC converter  59 . 
         [0067]    The DSP board  44  contains a plurality of devices connected to an embedded processor  60 . The processor  60  performs the processing, communicating, and controlling of the components connected to the board  44  and/or included in the device  20 . In some embodiments, the processor  60  includes a digital signal processor and/or an ARM-based or x822-based microprocessor. In some embodiments, the processor  60  can also be a variant of a DSP. For example, the processor  60  can include a DSP, such as the TMS320DM642 or TMS320DM6446 or any single of dual core ARM-based or x86-based processor and DSP combination, manufactured by Texas Instruments, ARM licensed manufacturers, and Intel Inc. 
         [0068]    The device  20  includes one or more input, output, and auxiliary devices that connect to the processor  60 . For example, the processor  60  can interface with an internal flash read-only memory (“ROM”)  61 , secure digital (“SD”) random-access memory (“RAM”)  62 , and an external SD card  63 . Flash ROM  61  can contain firmware or operating system code and can contain face templates for secure non-volatile storage. SDRAM  62  can be used for processing and general-purpose volatile storage of data. SD card  63  is a detachable storage medium that can be used to store records (e.g., evidence pictures) and data processing. 
         [0069]    The camera board  46  is one input device for the processor  60 . The camera board  46  includes a visible light color CCD/CMOS camera  64  (see  FIG. 3 ) that contains a CCD/CMOS sensor  66 , a focus lens  68 , and imaging stabilization and preprocessing logic. The camera board  46  also contains an infrared CCD/CMOS camera  70  (see  FIG. 3 ) that contains a CCD/CMOS sensor  72 , a focus lens  74 , a visible-light-block/infrared-pass filter  76 , and imaging stabilizing and preprocessing logic. Both cameras  64  and  70  are adjusted at an angle suitable for 3D imaging. 
         [0070]    Scanner infrared illuminator board  48  is an auxiliary device connected to the processor  60  and is part of a biometric facial recognition system. The board  48  is used to properly illuminate the face of a subject with infrared light. In some embodiments, the scanner infrared illuminator board  48  consists of an array of infrared LEDs  77  powered by intelligent infrared controller and driver circuitry  78 . 
         [0071]    The keypad  50  is an input device connected to the processor  60  and provides part of the user interface  51  of the device  20 . The keypad  50  includes a capacitive touch pad  79  and is processed by a touch controller  80 . The touch controller  80  translates touch events to the keypad key codes for further processing by the processor  60 . 
         [0072]    The LCD screen  52  is an output device connected to the processor  60  and used to provide a graphical user interface (“GUI”). The LCD screen  52  is controlled by an LCD controller  81 . In some embodiments, the LCD screen  52  is also an input device and includes a touchscreen controlled by a touchscreen controller  82 . The touchscreen controller  82  (when used) is also connected to the processor  60 . The touchscreen controller  82  translates user interaction with the GUI on the LCD screen  52  for processing by the processor  60 . 
         [0073]    The RFID antenna  54  is controlled by an RFID controller (e.g., EM/DESFIRE/MIFARE/HID compatible)  83 . The RFID antenna  54  and the RFID controller  83  form a RFID proximity reader, which is an input device for the processor  60 . The RFID controller  83  energizes a RFID tag (e.g., carried by a worker) with the RFID antenna  54  when the tag is presented near the RFID antenna  54 , receives an emitted signal from RFID tag with the RFID antenna  54 , and decodes the emitted signal to a RFID code that is provided to the processor  60 . It should be understood that in some embodiments, the RFID antenna  54  and/or the RFID controller  83  can be positioned outside of the housing  40  and  42  of the device  20  but can be electrically connected with the device  20  to exchange data (e.g., see  FIGS. 11 a, b , and  c   ). 
         [0074]    To enhance the user experience on the device  20 , different audio messages can be output by the processor  60  for different events at the device  20 . Audio output is amplified by an amplifier  84  and fed to the speaker  56 . In some embodiments, the device  20  includes multiple speakers. For example, as illustrated in  FIG. 2 , the device  20  can include a speaker  85  on the housing back  42 . Volume control can be provided by GUI settings that adjust the amplification of the amplifier  84  programmatically. 
         [0075]    AC Line connecter  86  provides the 100-240 Volts AC (“Alternating Current”) to the AC/DC Converter  59 , which converts the high AC voltages to the low DC (“Direct Current”) voltage. To provide power to the peripherals and devices included in the device  20 , the device  20  includes a power management controller  87  that intelligently manages the power of the peripherals and devices, such as a scanner, the IR illuminator, and memory. The power indicator LED  58  displays the status of the power. 
         [0076]    As illustrated in  FIG. 4 , the device  20  also includes a network communication controller  100  that provides network connectivity on one or multiple interfaces. For example, the device  20  can include a local area network (“LAN”) port  102  that provides wired network connectivity, a WIFI radio  104  that provides wireless network connectivity, and/or a general packet radio service (“GPRS”) interface that provides wireless network connectivity over cellular global system for mobile communications (“GSM”) with GSM/GPRS radio  106 . The GSM/GPRS radio  106  can provide long distance connectivity on the TCP/IP protocol. It should be understood that the network communication controller  100  is not limited to the stated interfaces and can include interfaces to additional or different networks or communication systems. 
         [0077]    To meet industry standards for access control, device  20  provides a mono or bidirectional, configurable Wiegand interface controller  110  connected with a W/G port  112  to connect to external access controllers. Configurable Wiegand controller  110  can be configured to the desired Wiegand protocol for external access controllers programmatically or from the GUI interface of the device  20 . 
         [0078]    The device  20  also includes a relay driver and controller  120  that controls an electric relay switch  122 , which controls an external electric lock  124  via a relay port. Action of the electric relay switch  122  is controlled programmatically by the processor  60 . 
         [0079]    In some embodiments, a universal serial bus (“USB”) flash disk can be connected to the device  20  through a USB port  130 . The port  130  is connected to a USB controller  132 , which is connected to the processor  60 . USB port  130  can be used to download and upload different kind of data to and from the device  20 . 
         [0080]    A real-time clock (“RTC”)  140  can be connected to the processor  60  to keep accurate time and date information for processing the date and/or time of particular events. In some embodiments, the RTC  140  includes a battery backup so it maintains accurate time even when the device  20  is powered off. Another clock  142  provides a heartbeat to processor  60 . General purpose logic  144  provides connectivity between the device  20  and all other connected devices and interfaces. As illustrated in  FIG. 2 , the device  20  can include a logo or other brand information  150  (e.g., on the housing front  40 ). 
         [0081]    The device  20  is an embedded device and it is designed to perform biometric identification, such as 3D face recognition, by taking advantage of high-speed DSP processing performed by the single or multi core processor combination included in the processor  60 , which eliminates the need for expensive hardware. The processor  60  can run an operating system, such as embedded Linux or Android. The processor  60  also executes application software that employs customized and enhanced algorithms for performing biometric identification and recognition while taking advantage of the capabilities of the processor  60 . 
         [0082]    The camera board  46  provides a face scanner that provides two types of video feed: (1) a color feed from the color camera  64  and (2) an infrared feed from the infrared camera  70 . Both feeds are provided to the processor  60 . As noted above, the scanner IR illuminator board  48  provides optimal infrared illumination to sample the infrared video from the infrared camera  70  of a subject. In some embodiments, due to the stereoscopic nature and the angle between the two cameras  64  and  70 , the application firmware can perform 3D reconstruction of the face of a subject. In some embodiments, the application software executed by the device  20  can provide 1:1 (“one-to-one”) biometric recognition (e.g., one identified identity of a subject). 
         [0083]    The device  20  stores biometric templates (described below) in a secure non-volatile storage, such as the flash ROM  61 , and uses the volatile SDRAM  62  to perform software processing. The SD card  63  can be used for the external storage of the captured frontal pictures of subjects, clock-in and clock-out data, attendance logs, and biometric operation logs. The USB controller  132  and the USB port  130  provide data transfer capability from memories  61 ,  62 , or  63  to other storage mediums located external to the device  20 , such as a USB flash drive. 
         [0084]      FIGS. 5 a, b , and  c    illustrate using the device  20  in sunlight. As discussed above with respect to  FIG. 1 d   , improper lighting conditions can cause the device  20  to malfunction. In particular, face, iris, and retina recognition techniques do not work properly when performed under partial or complete direct sunlight. Accordingly, as described above, opaque walls  38  without windows or portals can be used to block sunlight to area where the device  20  are installed. In some embodiments, rather than using the opaque walls  38 , filters can be used to prevent unwanted light from reaching the device  20 . For example, as illustrated in  FIG. 5 c   , direct sunlight has two kinds of light: (1) visible light  300  and infrared light  301 , which directly affects the operation of a device  20 . Accordingly, an infrared block/visible-light pass film/coating  302  can be overlaid on a transparent window or partition  303  positioned next to a sunlit environment. The film/coating  302  blocks the infrared light  301 , but lets the visible light  300  pass through the window or partition  303 . Thus, the room containing the device  20  can be lit with visible light  300  but the infrared light is blocked out of the room  30 . Accordingly, the room containing the device can function as an indoor environment for the device  20  while being fully lit with outdoor sunlight through any number of walls or a ceiling made of transparent glass overlaid with the film  302 . 
         [0085]    Furthermore, as noted above, the filter  76  is overlaid on the infrared camera  70 , which lets infrared light  301  pass but blocks visible light  300  from reaching the infrared camera  70 . Therefore, visible light  300  from sunlight or other sources, like a light bulb  304 , is blocked by the filter  76 . As also noted above, the device  20  uses the infrared illuminator board  48  to illuminate the subject&#39;s face and eyes with infrared light  301 . This helps the infrared camera  70  obtain quality infrared imaging needed for performing facial, iris, and retinal recognition in singular form or in a combination. 
         [0086]    Using the above setup (i.e., the film  302 , filter  76 , and illuminator board  48 ), allows for facial, iris, and retinal recognition even in sunlight, which reduces setup infrastructure costs and helps increase security. Accordingly, an access control point  16  can be located in an environment as illustrated in  FIG. 5 b    (i.e., with a transparent wall or window  305 ) rather than being restricted to an environment as illustrated in  FIG. 5 a    (i.e., with an opaque wall  38 ). 
         [0087]      FIGS. 6 and 7  are flowcharts illustrating an eyes-and-face recognition method performed by the device  20 . In some embodiments, the device  20  is configured to shift to an idle mode after a cold boot. A detection mode, such as a face detection mode, however, can be turned on by motion detected by the camera  64  or when an RFID tag is detected through the RFID reader (i.e., the RFID controller  83  and the RFID Antenna  54 ). The face detection mode triggers 3D reconstruction through the stereo vision feed from both the optical camera  64  and the IR camera  70 . The device  20  then performs a (1:1):1 recognition of the left eye and the right eye and the 3D face, as illustrated in  FIG. 6 . 
         [0088]    In some embodiments, the biometric templates of the left eye, right eye and the 3D face of a worker are stored in separate databases of the device  20 . Therefore, while matching a face, the left and right eyes can be detected, extracted, and separated. The device  20  can then run an index matching routine individually on each component (i.e., the left eye and the right eye) and compare the results to each other in the respective database to extract possible worker identity matches that are further matched with the extracted 3D face matched through the related 3D face templates (see  FIG. 7 ). Separately processing these components increases the speed of matching through multiple sources in the same field-of-view and helps eliminate the need of a card setup used in some existing recognition systems, which are prone to card loss and theft. Also, in some embodiments, as illustrated in  FIG. 6 , the device  20  is configured to detect a gender of a subject based on a captured image (e.g., based on a face identified in the image). Using the detected gender, the device  20  can select a subset of the available biometric templates (e.g., a particular database) that is associated with the detected gender. Using gender-specific templates reduces the amount of processing (and associated time) needed to determine a match. 
         [0089]    Upon finding a match to all three components, the device  20  plays a visual and/or audio message. The device  20  also generates and stores time stamp data and an evidence picture against the identified worker identity (e.g., on the SD card  63 ). In addition, the device  20  can trigger a lock to allow the worker to pass through the access control point  16  (if allowed for that worker under the employer&#39;s policy). The device  20  can also send a Wiegand code to Wiegand readers or the server  12  and/or push a record to another device or to the cloud, such as over TCP/IP. 
         [0090]    Accordingly, the device  20  acts as a standalone device that saves and matches biometric templates. However, the device  20  can be configured to push data (see  FIG. 10 a   ) to external devices or systems, which simulates server-based recognition functionality. The device  20  is also specifically designed to address challenges of workforce management overlapping with other verticals. In particular, existing devices address security requirements (e.g., with simple clock-in and clock-out functionality) but do not help with other workforce management functions. As noted above, however, the device  20  is configured to integrate with other systems involving various components of workforce management, such as HR, payroll, customer relationship, enterprise resource planning, banking and financial transactions, supply chain, warehouse, asset, infrastructure, training, access control, production, administration, security management, voting, and ticketing. 
         [0091]    As illustrated in  FIG. 7 , the device  20  can be configured to automatically shift to a 1:N (“one to many”) face-only matching mode from a (1:1):1 eyes-and-face matching mode. For example, the device  20  can be configured to shift to the face-only matching mode when eye detection and/or recognition fails. In some embodiments, the face-only matching mode applies the same biometric templates associated with a worker&#39;s face as used in the eyes-and-face matching mode. However, in other embodiments, the face-only matching mode can use a separate database of templates. 
         [0092]    If a worker has a problem enrolling with the device  20  due to any problem with one or both of his or her eyes, the worker can be enrolled with his or her eyes closed under the face-only matching mode. After enrolling with the device  20  with his or her eyes closed, the worker can be identified by the device by similarly presenting his or her face with eyes closed. For example, in some embodiments, when the device  20  detects a face without eyes, the device  20  automatically shifts into the face-only matching mode, which can match a scanned face with templates (e.g., stored in a face-only database). It is estimated that over 8% of the world population suffers from various types of eye diseases that makes it difficult for them to be enrolled onto an iris-based or retina-based biometric device. However, the process defined above for the device  20  can be used to both enroll and later identify the worker without requiring exception handling or reprogramming. In particular, the ability of the device  20  to automatically shift from capturing one biometric feature to another increases the efficiency and reliability for worker recognition and workforce management. 
         [0093]      FIG. 8  is a flowchart that illustrates template capacity of the device  20 . In an unlimited-capacity mode, biometric templates are separated and grouped into multiple databases, and the limit of the template groups is only limited based on the available data storage on the device  20  (e.g., size of the SD card  63 ). In some embodiments, each template group includes approximately 1,000 biometric templates. When template groups are used, the device  20  can be configured to prompt a worker to select his or her template group (e.g., on the LCD screen  52 ). Upon receiving a selection of a template group, the worker&#39;s biometric features are matched only in the selected template group database. Accordingly, creating groups of templates helps increase the limit of template capacity of the device  20  while keeping the matching speed efficient by limiting the number of templates the device  20  has to process to perform a match. 
         [0094]      FIG. 9 a    illustrates the device  20  paired with a palm vein reader  400 . As illustrated in  FIG. 9 a   , the device  20  and the reader  400  can both be mounted on a support  402  and can be connected electrically (e.g., by a wired connection) that allows the devices to exchange information. The palm vein reader  400  and the device  20  can be used to perform a palm-eyes-and-face recognition. In some embodiments, this matching process results in a 1 {(1:1):1} match. 
         [0095]      FIG. 9 b    illustrates a process for performing a match using the palm vein reader  400 . As illustrated in  FIG. 9 b   , the device  20  can be configured to shift to idle mode after a cold boot. However, when a worker hovers his or her hand over the reader  400 , the device  20  receives notice of this motion from the reader  400  and the device  20  automatically shifts to face detection mode. The reader  400  then performs a palm-vein matching method to extract the worker&#39;s identification and the reader pushes the identification to the device  20 . The device  20  receives the identification and executes the face detection mode, which triggers 3D reconstruction through the stereo vision feed from both the optical camera  64  and the IR camera  70  simultaneously. The device  20  then performs an eye-and-face matching method as shown in  FIG. 7 . 
         [0096]      FIG. 10 a    is a flowchart illustrating a pull method performed by the device  20 , and  FIG. 10 b    is a flowchart illustrating a push method performed by the device  20 . In some embodiments, both methods can be used to manage time and attendance data captured by the device. The device  20  can be configured to perform two types of simultaneous data transaction methods to ensure no transaction or data is loss in transit between the device  20  and server  12 . For example, the two streams can be cross-compared before final settlement of data on the server  12 . In the pull method illustrated in  FIG. 10 a   , the server  12  sends requests to the device  20  over the connection  14 , and the device  20  transmits data to the server  12  in response. In the push method illustrated in  FIG. 10 b   , the device  20  pushes the data to the server  12  as the device  20  receives the data and/or per the availability of the connection  14 . Before, during, and after transmitting the data, the unavailability of the connection  14  is considered by the device  20 , and the device  20  re-transmits the data unless the data is received by the server  12  and the server  12  sends the confirmation back to device  20 . The server  12  compares data received by the push and pull methods and, upon final confirmation, sends a command to the device  20  to delete (e.g., erase and/or overwrite) data successfully transmitted to the server  12 . Accordingly, the device  20  can eliminate data loss, which is not acceptable for even a single transaction of time and attendance data or other types of transactions, including financial transactions. Existing biometric devices do not give importance to this matter and are prone to data loss, which causes failures in down-stream workforce management systems. 
         [0097]    In some embodiments, the device  20  can be installed with an automatic height control system. For example, as illustrated in  FIGS. 11 a, b , and  c   , the height of the device  20  can be automatically adjusted based on the height of the worker interacting with the device  20 . For example, the device  20  can be fixed on top of a free moving pole  450  controlled by a motor driver. During initialization of the device  20 , the pole  450  is driven to a default height to cater to a worker of average or medium height (e.g., worker  601 , illustrated in  FIG. 11 a   , B). Workers with a shorter-than-average height (e.g., worker  602 , illustrated in  FIG. 11 a   , A) and workers with a taller-than-average height (e.g., worker  603 , illustrated in  FIG. 11 a   , C) can be issued RFID tags  604   a  and  604   b . It should be understood that in some embodiments all workers can be issued RFID tags that identify a height code. However, in some embodiments, workers with average heights (e.g., the worker  601 ), do not need an RFID tag to use the device  20  at its default position as per the process discussed in  FIG. 6 . 
         [0098]    To adjust the device&#39;s height, worker  602  shows his or her RFID tag  604   a  to the RFID antenna  45 , which signals an RFID code that is matched to a “short” height code stored in a database (e.g., locally-stored in the RFID controller  83 ). The height code will then be used to automatically move the pole  450  down per “short” height settings associated with the “short” height code. The worker  602  can then use the device  20 , and, after the device  20  captures the necessary data regarding the worker  602 , the pole  450  can be returned to its default height (see, e.g.,  FIG. 11 a   , B). A similar process is performed to accommodate the worker  603  and drive the pole  450  to a taller height than its default position. For example,  FIG. 11 d    is a flowchart illustrating a process for adjusting the device  20  height. 
         [0099]    It should be understood that the RFID controller  83 , motor driver  452 , the device  20 , or combinations thereof can be configured to control the height of the pole  450  based on the detected RFID tag. For example, in some embodiments, the RFID antenna  54  is positioned within the turnstile  22  and transmits detected tags to the RFID controller  83  included in the device  20  (e.g., over a wired connection between the antenna  54  and the device  20 ). The device  20  can process codes identified by the controller  83  based on the detected tags, and the device  20  can then issue a command to the motor driver  452  to position the pole  450  at a particular height. In other embodiments, a controller position in the turnstile  22  with the antenna  54  can be configured to detect and process codes received from the RFID tags and issue a command directly to the motor driver  452  without interaction with the device  20 . 
         [0100]    Furthermore, as noted above and as illustrated in  FIGS. 11 a, b , and  c   , in some embodiments, the RFID antenna  54  can be positioned outside of the housing  40  and  42  of the device  20 . For example, the antenna  54  can be positioned at a lower height than the device  20  to allow workers of all heights (including workers in wheelchairs) to use the antenna  54  to adjust the height of the device  20 . Existing biometric devices are often installed at a fixed height which makes it difficult for short and tall workers to mark their attendance. Accordingly, the automatic height adjustment described above solves this problem. Furthermore, the RFID antenna  54  is a cheaper implementation than providing button control for manually adjusting the height. In some embodiments, the palm vein reader  400  can similarly be used to obtain a height or other position code from a worker (e.g., associated with an identification of the worker) and can send the height data to the motor driver  452 . 
         [0101]    It should also be understood that in some embodiments, the RFID tags can be configured with codes that identify not only a height of the device  20  but other positions and/or settings. For example, as illustrated in  FIG. 11 c   , in some embodiments, the device  20  can be installed at approximately the center of a turnstile  22  so that the same device  20  can be used for both inward and outward traffic (e.g., in areas with light traffic). The device  20  can pivot on top of a pole  460  rotatable by a motor driver  462 . One or more buttons can be installed on the turnstile  22  and/or the device  20 . For example, the turnstile  22  can include a left button and a right button. When the left button is pressed, a command is sent to the motor driver  462  that rotates the device  20  to face inward traffic, which sets the status of the device  20  to “IN.” When the right button is pressed, a command is sent to the motor driver  462  that rotates the device  20  to face outward traffic, which sets the status of the device  20  to “OUT.” In other embodiments, an RFID antenna on each end of the turnstile  22  can be used to detect a direction of traffic and set a status of the device  20  accordingly. Existing systems typically require two devices  20  to manage both inward and outward traffic. Accordingly, using the rotatable device  20  as illustrated in  FIG. 11 c    reduces the costs while preserving data capture functionality. 
         [0102]    In a standard setup, as illustrated in  FIG. 12 a   , the device  20  matches a worker&#39;s biometric features and signals the turnstile  22  directly to open the lock and let the worker enter or exit the area and clock him or her “IN” or “OUT.” In an alternative setup, the device  20  is connected to a computing device  700 , such as an Android-based tablet, that is connected to the turnstile  22  (see  FIG. 12 b   ). The policies and rules are set on the server  12  and are pushed to the computing device  700  over the connection  14 . When a worker successfully marks his attendance on the device  20 , an identifier of the worker is sent to the computing device  700 , which takes further action as per the policies set by the server  12 . 
         [0103]    For example, if the policies and rules are matched for the worker (e.g., per a database stored on the computing device  700 ), the computing device  700  signals the turnstile  22  to unlock and let the worker pass. The attendance data can also be stored on the computing device  700  and synched with the server  12  as described above with respect to  FIGS. 10 a  and 10 b   . If the policies and rules are not matched for the worker, the computing device  700  will prompt the worker (e.g., on a screen of the computing device  700 ) for additional information based on a worker level associated with the worker (e.g., per the database stored on the computing device  700 ). If the worker level is set as “manager,” the device  700  will allow the worker to override the policy and enter on his or her own decision. If the worker level is set as “staff” the worker will have an option to request access (associated with selectable reasons for the request). If the request is granted, the worker will be notified (e.g., over a text message to a cellular telephone) of a code that the worker can enter into the device  700  to gain access. If the worker level is set as “labor,” the worker is not provided any further options and must accept the denial of access. Existing systems are only able to match a worker and clock the worker “IN” or “OUT.” Accordingly, the device  20  can perform additional functionality to enforce HR, security, administrative, overtime and other policies and provide decision support for the enforcement of the policies. 
         [0104]      FIG. 13  is a flowchart that illustrates the use of surveys with the device  20  and the computing device  700 . Surveys for individual workers can be created (e.g., with supported text and graphics) and stored on the server  12 , which are then synched over the connection  14  with the computing device  700 . When a worker marks his attendance on a device  20  connected to the computing device  700 , the device  700  displays the survey created for him or her (e.g., on a touchscreen of the computing device), which the worker completes using the computing device  700  (e.g., the touchscreen). Upon completing the survey, the computing device  700  passes a signal to the turnstile  22  to unlock and let the worker pass. The survey input is stored in the database of the computing device  700  and is synched with the server  12  over the connection  14 . Survey questions may vary from “Would you like to have the meal today?” which may help the kitchen to know how many meals to be prepared, or “Which drink would you prefer at the cafeteria, Pespi or Coke?” to identify suppliers to contract with. Similarly, the computing device  700  can act as a voting system to know worker choices and make better HR policies for the workers. 
         [0105]      FIG. 14 a    is a flowchart that illustrates the use of multi-status physical access control with the device  20  or any RFID device. In this configuration, special sensors are integrated into the turnstile  22  to get additional data to determine if a worker actually entered or exited after clocking “IN” or “OUT.” For example, in some embodiments, attendance records stored on the device  20  can have one of three levels: (1) The worker was able to successfully mark his attendance; (2) The turnstile  22  opened and/or a tripod was rotated; and (3) The worker crossed the other end of turnstile  22 . This fraud prevention method is used to determine if a worker clocked-in on a device  20  but did not actually enter the work area. The server  12  can be configured to determine whether to accept a clock-in or not based on the status of the clock attempt. 
         [0106]    Similarly,  FIG. 14 b    is a flowchart that illustrates the use of multi-status non-physical access control with a device  20  or any RFID device. As illustrated in  FIG. 14 c   , a combination of proximity sensors  730 , laser light source and associated sensors  732 , and a projector  734  can be installed in a turnstile  22 . In some embodiments, however, the devices  730 ,  732 , and  734  can be controlled by an intelligent controller without any tangible turnstile  22 . The proximity sensors  730  are capable of motion detection in both directions. Laser light source and associated sensors  732  are used to mimic a barrier or gate and are also used for intrusion detection. The projector  734  is used to display different signs  736  on the floor for access control (e.g., “Stop” or “Go”). The device  20  and/or the separate intelligent controller is responsible for control and communication between the different devices. 
         [0107]    Using the devices  730 ,  732 , and  734  allows the access control point  16  to perform intrusion detection, bi-directional movement sensing, and sensing the numbers of people passing through (e.g. if only one person is allowed to pass but more than one person attempts to pass, an alarm will be issued and the event will be saved). Accordingly, the multi-status non-physical access control can provide three types of status information: (1) clock-in and clock-out information; (2) intrusion detection; and (3) a number of people passing through. The multi-status non-physical access control can maintain a batter-backed calendar, a real-time clock, and an event counter to provide accurate status information. The modular design of the multi-status non-physical access control aids integration with other components of the system  10 . Multi-status non-physical access control also is an effective and cost-cutting discipline enforcement solution. 
         [0108]      FIG. 15 a    is an exemplary illustration of a device  20  used with asset protection. Similarly,  FIG. 15 b    is a flowchart that illustrates the use of asset protection with the device  20 . To perform asset protection, asset tags  750  are attached to expensive assets, such as laptops and mobile phones and are assigned to a particular worker&#39;s profile on the server  12 . A tag reader (e.g., medium range)  752  is attached to the device  20 . If a worker brings an asset with a tag  750 , such as a laptop or a mobile phone, in the proximity of the tag reader  752 , information collected from the tag  750  is passed to the device  20  and the device  20  matches the information with the worker attempting to gain access. If the asset tag  750  matches the identified worker&#39;s profile, the device  20  grants the worker access. If the asset tag  705  does not match with the worker&#39;s profile, the device  20  prevents the worker from passing through the turnstile  22 . In some embodiments, if the asset tag  750  does not match, the device  20  is also configured to trigger an alarm or notification. Accordingly, the asset protection adds a layer of protection of assets, which reduces the asset theft cases, and, consequently, can reduce insurance costs. 
         [0109]    In some embodiments, a device  20  can be integrated with a metal detector, such as a walk-through metal detector  800 , as illustrated in  FIG. 16 a   .  FIG. 16 b    is a flowchart that illustrates the use of the metal detector integrated with the device  20 . The device  20  can be integrated into the ceiling of a walk-through metal detector  800  and is connected to the server  12  over the connection  14 . With this configuration, the worker must look up while walking through the detector  800 . If the worker attempted and is granted access, a first (e.g., green) light  802  on the detector  800  can flash, which informs the worker that he or she can walk-through the detector  800  where the worker and the contents he or she carries will be scanned. Data gathered by the detector  800  can be stored in a database. For example, metal contents allowed in with a worker can be stored in a database and compared with metal contents carried by the worker at the time of exiting. If a worker is not identified by the device  20 , a second (e.g., red) light  804  will flash and, in some embodiments, a security alarm will be triggered. 
         [0110]      FIG. 17  is a flowchart that illustrates using a name method executed by the device  20 . Names of workers are saved in text and audio form on the server  12 , which are synched with the device  20 . When a worker uses the device  20  to successfully mark his or her attendance, the device  20  plays the corresponding name audio file. If there is no audio file available for a particular worker, the device  20  executes a text-to-speech engine to convert the text of the worker&#39;s name into audio. Some existing systems play a fixed sound whenever a user successfully uses a biometric device. If there are a large number of such devices installed in close proximity, however, the sounds can confuse a user because a user does not know if the sound they heard was from the device they were using or a different device. Accordingly, configuring the device  20  to play the worker&#39;s own name increases the efficiency of the system  10  and the confidence of the worker. 
         [0111]      FIG. 18  is a flowchart that illustrates an emergency disaster recovery method executed by the device  20 . As noted above, biometric templates and applicable policies are synched between the device  20  and the server  12 . If the device  20  fails to function, the device  20  can be replaced with a new device assigned the same IP address as the failing device. Therefore, the new device  20  will be automatically synched with the same biometric templates and applicable policies from the server  12 . Accordingly, automatically re-synching a new device from the server  12  offers a painless recovery of the system  10 . 
         [0112]    In some embodiments, there are two types of problems that may arise during the normal functionality of the system  10 : (1) data corruption of secured data storage included in the device  20 ; and (2) replacement of a device  20  with a new device  20 . Two types of data are stored in the device  20 : (1) biometric templates and (2) clock-in and clock-out and other log files. To download and upload data from and to a device  20  in either of the above situations, a system administrator can choose a direct connection or a network connection. For direct data transfers from a device  20 , a system administration can use a SanDisk or Kingston-compatible USB flash disk (i.e., a USB thumb drive) on USB port  130  of the device  20 . 
         [0113]      FIG. 19  is a flowchart that illustrates video conference and remote lock operations executed by the device  20 . These operations are implemented by a combination of a mobile device (e.g., a smart phone, capable of utilizing the TCP/IP services with a WIFI/3G/LTE or GSM/GPRS radio) and a front facing camera. In particular, a software application is installed on both the device  20  and the remote mobile device. The application provides audio and/or video streaming on both devices. When a call button is pushed on the device, if the status is set to a “BELL” mode, the device  20  will play a sound (e.g., a door bell sound). Otherwise, if the status is set to a “PHONE” mode, the device  20  attempts to connect the remote mobile device and initiate a call (e.g., a voice-over-IP (“VOIP”) call). On accepting the call, the remote mobile device queries the device  20  for the hardware capabilities of the device  20 . If the device  20  is connected to an electric lock  124 , an “Open Lock” button may appear in a graphical user interface (“GUI”) displayed by the software application installed on the mobile device. In some embodiments, audio and/or video streaming is also automatically started on both devices after the call is accepted. Accordingly, the user of the mobile device can see and, optionally talk to the worker interacting with the device  20 . If the “Open Lock” Button is pressed on the mobile device, the mobile device verifies a code (e.g., a PIN input by the user of the mobile device or stored in the mobile device). After verifying the code, the mobile device sends a signal to the device  20  to open the connected electric lock. Therefore, the device  20  allows not only remote access of the electric lock  124  but also ensures security and maintains a history record or log of the events related to the device  20  performed through the mobile device. This integration offers convenience to a user to talk to and see the person trying to access a particular area through the device  20  and gives the user power to allow access if required even if the user is located remote from the device  20 . For example, this integration can be used in residential towers and buildings, such as when a dog walker, nanny, or other individuals needs access to a location when the residence owner is away from home (e.g., at work or on vacation). 
         [0114]      FIG. 20  is a flowchart that illustrates the use of a payment method executed by the device  20 . For example, the payment method integration with a device  20  at a cashier window helps to speed up a payment procedure performed at the window and keep transactions secure. For example, the device  20  recognizes the worker&#39;s face, and the device  20  pushes the identifier of the worker to a payroll server (e.g., the server  12  or a separate server). The payroll server translates the identifier to payroll-related information, which is displayed on a display screen of the cashier and allows the cashier to securely conduct financial transactions with the worker. 
         [0115]      FIG. 21  is a flowchart that illustrates the use of a cash dispenser with the device  20 . Integration of the cash dispenser with the device  20  allows robust and more secure financial transactions through an automated teller machine (“ATM”). In particular, ATM card information and a PIN collected through the ATM can be cross-matched against the recognized worker&#39;s biometric identity by the device  20 . An identifier of the identified worker is pushed from the device  20  to a payroll server (e.g., the server  12  and/or a separate server) where the identifier is translated to payroll-related information. This information is used to allow the worker to withdraw funds based on the payroll-related information (as a regular payroll payment or as an advance payment) through the ATM. Accordingly, this integration increases the reliability and security of cash transactions with workers by mitigating identity-theft frauds. 
         [0116]      FIG. 22  is a flowchart that illustrates a triggered-reporting method integrated with the system  10 . The triggered-reporting method is an implementation of a “management by exception” policy for work force management. In particular, a reporting engine executed by the device  20  determines the level of exception to be reported to management by cross-examining predefined values of variables during the processing of various reports. The triggered reports are then pushed on different mediums of communication enforced by a triggered reporting policy. In contrast to existing reporting solutions, the triggered-reporting method helps to produce more meaningful and essential reports for work force management. Moreover, the triggered-reporting method can be employed for Facebook and other check-in and loyalty management programs and applications. 
         [0117]      FIG. 23  illustrates a vending machine (e.g., a coffee vending machine)  830  integrated with the device  20 . The integration of the vending machine  830  with the device  20  is a unique combination that allows automated biometric-controlled vending (e.g., a personalized cup of coffee). In particular, the device  20  can push a recognized identity of a worker to the server  12 , which translates the identity to personalized options for the vending machine  830  (e.g., personalized options of coffee recipes). The options can then be displayed on the device  20  and/or the machine  830  (e.g., a touch screen display), and the worker can select one of the options. The device  20  and/or the machine  830  can keep a record of the selections of the workers, which can be used to analyze moods of the work force, which may help calculate trends or performance of the work force. In some embodiments, the vending machine  830  and the device  20  can be further integrated with a payroll system to allow workers to purchase items from the vending machine  830  from their salary (see, e.g.,  FIGS. 20 and 21  above). 
         [0118]      FIG. 24 a    is a flowchart that illustrates using a field worker management system. The system allows a field worker to mark attendance and receive work orders based on the worker&#39;s current geographic location. For example, a field biometric scanning device  850  is illustrated in  FIG. 24 b   . The field device  850  is a combination of a camera  852  (e.g., an infrared camera), fingerprint reader  854 , global positioning system (“GPS”) receiver, and a GSM/GPRS modem. The field device  850  connects to a mobile device  856 , such as a laptop or tablet computer via a wired connection  857 , such as a USB connection. The GPS receiver acquires a geographic location (e.g., latitude and longitude) from at least one GPS satellite  858 . The GSM/GPRS modem provides a connection to the server  12  (e.g., a TCP/IP connection) over a cellular network. The mobile device  856  receives video captured by the camera  852  and fingerprint data captured by the fingerprint reader  854 . Biometric algorithms performed by software executed by the mobile device  856  determines the biometric facial and fingerprint identifications and sends the identifications to the server  12  along with a geographic location from the GPS receiver through the GSM/GPRS modem. The server  12  identifies a worker based on the transmitted identifications and translates the geographic location to a client location where the worker was expected to work, and marks the attendance with the geographic location and time information. 
         [0119]    In some embodiments, after processing the location of an identified worker at an identified client location, the server  12  produces a work order  860  with one or more tasks the worker should conduct at the client location. The work order  860  is downloaded to and displayed on the mobile device  856  from which the request was generated through the field device  850 . As the worker progresses through the tasks, the mobile device  850  notifies the server  12  (e.g., in approximately real-time). Accordingly, although matching field workers and task management at multiple client locations with a large workforce is a challenging job, the field worker management system, including the field device  850 , manages these working arrangements and can be integrated with payroll and other systems as described above for the device  20 . By tracking individual tasks on a work order  860 , the field worker management system can pay workers on a per task basis, which enhances performance of the workforce. 
         [0120]      FIG. 25  is a flowchart that illustrates using a portable biometric scanning device (“portable BSD”) that integrates with the system  10 . The portable BSD can be similar to the field device  850  and mobile device  856  described above with respect to  FIGS. 24 a  and 24 b   . For example, the portable BSD includes a portable mobile device with a built-in battery (e.g., a smart phone, tablet computer, laptop computer, etc.) connected with an iris and/or infrared camera, a fingerprint reader, or both. The portable BSD also includes a GPS receiver and a GSM/GPRS modem. 
         [0121]    A user interface provided by the portable device contains a “clock-in” button (e.g., a push button), an electromagnetic speaker for audio, and, optionally, a display for user interactions. The GPS receiver acquires a geographic location (i.e., latitude and longitude), and the GSM/GPRS modem provides connection servers (e.g., TCP/IP services) over a cellular network. On pressing the clock-in button, iris images from the camera and a fingerprint data from the fingerprint reader are captured and sent to the server  12  via the GSM/GPRS modem along with the geographic location from the GPS receiver and timestamp information. Biometric algorithm software executed by the server  12  recognizes the biometric iris and/or fingerprint and identifies the worker. The software also translates the geographic location to a work location and/or work zone where the worker was expected to work. Furthermore, the software marks the worker&#39;s attendance after verifying the biometric identifiers with the geographic location. The server  12  sends results back to the portable BSD. If the result of the request is granted (the worker and his or her location was verified by the server  12 ), the portable BSD plays a verification sound (e.g., a beep) through the speaker. Otherwise, the portable BSD plays an error sounds. Existing portable workforce systems do not collect biometric and geographic data that is tightly integrated with workforce management system. 
         [0122]    Accordingly, the portable BSD helps to manage a remote workforce, such as traffic police, report their location and time while working from anywhere. In some embodiments, real-time GPS tracking of the portable BSD can be turned on and off, such as by issuing a command from the server  12 . 
         [0123]      FIG. 26 a    is a flowchart that illustrates a visitor management system integrated with the system  10 . In some embodiments, the visitor management system is a combination of a customized hardware and software solution. For example, a visitor management console  900  (hereinafter referred to as “console  900 ”) is illustrated in  FIG. 26 b   . The console  900  includes a camera  902  for capturing a front picture of the face of a visitor  903 , a card scanner  904 , and an RFID card reader  906 . The console  900  is connected to a computing device  910  (e.g., a tablet computer or laptop computer), via a connection  912 , such as a USB connection. The computing device  910  includes a screen  913  for interacting with an operator and managing visitor information. 
         [0124]    When the visitor  903  approaches the console  900 , an operator asks for a registration number if the visitor  903  visited previously. If the visitor  903  did not previously visit, a registration number is automatically generated. The visitor  603  is then asked to produce an identification card  914 , such as a national identity card, a driver&#39;s license, a social security card, etc., and stand in front of console  900 . The console  900  then automatically captures a front face photo of the visitor  903 , scans the card  914 , and issues a visitor RFID card  920 . The RFID access code associated with the new card  920  is also broadcast to one or more access control points  16  (e.g., a RFID-driven device  20  and/or turnstile  22 ). Likewise, if the visitor  903  is carrying personal items, the items are documented and corresponding RFID tags are issued. 
         [0125]    When the visitor  903  departs, the visitor management system unregisters the visitor RFID card  902  and any other RFID tags issued for the visitor  903  from the system and access control points and updates the history at the server  12 . Visitor management integrated with the system  10  is beneficial for a workforce management system because it provides data on which workers are getting external visitors and how much time the external visitors are consuming of such workers. This kind of data is not available with existing visitor management systems. 
         [0126]    In some embodiments, the visitor management system can also enforce visitor polices, such as meeting timings, number of visitors, time limits, frequent visits, group visits, etc. The visitor management system can also be configured to send notifications regarding visitors, such as text messages. 
         [0127]      FIG. 27  is a flowchart that illustrates the use of blacklisted-worker detection performed with the system  10 . For example, to prevent entry and/or enrollment of particular workers (i.e., “blacklisted workers”), the device  20  pushes recognized biometric identifiers to the server  12 , which cross-checks the biometric identifiers with a “blacklist” to allow or restrict access or enrollment. 
         [0128]      FIG. 28  is a flowchart that illustrates the use of very-important-person (“VIP”) management integrated with the device  20 . In particular, the device  20  recognizes and pushes biometric identifiers to the server  12 , which identifies the person&#39;s status. If a person&#39;s status is set to “VIP,” the server  12  pushes the details to a manager or assigned officer of the business to inform him or her of the VIP&#39;s presence. If policy allows, the server  12  may also push the information to a catering section of the business to offer personalized catering (e.g., refreshments) for the VIP. VIP management also keeps records of the VIPs, which can be used for analysis and trend calculations for future business planning. 
         [0129]      FIG. 29 a    is a flowchart that illustrates the use of augmented-reality glasses integrated with the system  10 . For example,  FIG. 29 b    illustrates a possible arrangement of such integration. The hardware of the glasses  950  (e.g. Google Glass) is capable of capturing real-time video with an integrated camera  952  and sending the captured video to the server  12 . The server  12  recognizes the person viewed by the wearer of the glasses  950  (i.e., using facial recognition as described above), transmits data to the glasses  950  (e.g., providing an identity of the viewed person) in approximately real-time. The returned data or at least a portion thereof is displayed on the glasses  950  themselves or heads up display (“HUD”)  954 . In some embodiments, the server  12  produces a report based on the identified person viewed by the glasses wearer (e.g., suitable for making quick decisions). The report is then transmitted back to the glasses  950 . This integrated can be designed for busy managers who work with large workforces and can increase worker and task management. 
         [0130]    Thus, embodiments of the invention provide, among other things, biometric scanning devices configured to collect biometric information from a worker and integrating the collected information with various workforce management systems, such as HR, payroll, security, work orders, task management, asset management, trend analysis, etc. It should be understood that the term “worker” as used in the present application can include any individual attempting to access a particular area or mark their presence at a particular location. Therefore, the term “worker” as used herein should be construed as being limited to employees of an employer. 
         [0131]    Various features of the invention are set forth in the following claims.
