Description:
BACKGROUND 
       [0001]    The use of in-store wireless transactions (e.g., via a personal communication device) has become increasingly popular. A user is not required to take out his/her wallet to swipe a physical card, and the transaction receipt can be displayed directly on the user&#39;s communication device. One popular wireless protocol used for in-store wireless transactions is Near Field Communication (NFC). However, NFC requires very close proximity (e.g., a few inches) between the user&#39;s communication device and an access device. As a result, the user may be required to hold the communication device close to the access device for a significant period of time. Further, the NFC connection is only open for a short period of time, preventing line item data associated with the transaction from being displayed on the communication device in real-time. 
         [0002]    Embodiments of the invention address these and other problems. 
       BRIEF SUMMARY 
       [0003]    In some embodiments of the invention, systems and methods for wireless payments using the Bluetooth low energy (BLE) protocol are provided. The BLE protocol may allow for a short-range wireless connection between a communication device and access device to remain open longer than other proximity technologies, such as NFC or Quick Response (QR) codes. This may be because BLE has a greater connection range than other proximity technologies, alleviating the need to continually hold the communication device to a reader (e.g., access device). For example, a Bluetooth or Bluetooth Low Energy (BLE) enabled device may have an extended range of ten to hundreds of feet or greater as compared to a range of less than a few inches for NFC. Further embodiments of the invention allow for transmission of line item (e.g., level III) data in real-time from the access device to the communication device, essentially occurring as items are “scanned” at the access device and transmitted back to the communication device in real-time over the open BLE connection. This may allow for a user to view the itemized details of a transaction on his/her communication device prior to completing the transaction. 
         [0004]    Some embodiments of the invention are directed to a method for facilitating a transaction. The method may include establishing, via a communication device, a wireless-short range communication link to a peripheral device associated with an access device. The method may also include receiving, by the communication device and from the peripheral device, item level data associated with an item being processed by the access device. The method may further include displaying, on display on the communication device, the item level data associated with the item. The method may additionally include in response to a user action, transmitting, by the communication device, payment data to the access device. 
         [0005]    In some embodiments, the wireless-short range communication link is a Bluetooth low energy (BLE) communication link. 
         [0006]    In some embodiments, the peripheral device is a BLE enabled device. 
         [0007]    In some embodiments, the access device processes the transaction based at least in part on the payment transmitted payment data. 
         [0008]    In some embodiments, the method may also include receiving, by the communication device and from the peripheral device, item level data associated with a second item being processed by the access device and displaying, on the display, the item level data associated with the second item. 
         [0009]    Some embodiments of the invention are directed to another method for facilitating a transaction. The method may include establishing, via a peripheral device associated with an access device, a wireless-short range communication link to a communication device. The method may also include transmitting, by the peripheral device and to the communication device, item level data associated with an item being processed by the access device, wherein the communication device displays the item level data associated with the item. The method may additionally include in response to a user action, receiving, by the peripheral device, payment data from the communication device. 
         [0010]    In some embodiments, the wireless-short range communication link is a Bluetooth low energy (BLE) communication link. 
         [0011]    In some embodiments, the peripheral device is a BLE enabled device. 
         [0012]    In some embodiments, the access device processes the transaction based at least in part on the payment transmitted payment data. 
         [0013]    In some embodiments, the method may also include transmitting, via the peripheral device and to the communication device, item level data associated with a second item being processed by the access device, wherein the communication device displays the item level data associated with the second item. 
         [0014]    Other embodiments of the invention are directed to servers and systems that are configured to perform the above-described methods. 
         [0015]    These and other embodiments of the invention are described in further detail below.

     DETAILED DESCRIPTION 
       [0023]    Prior to discussing embodiments of the invention, descriptions of some terms may be helpful in understanding embodiments of the invention. 
         [0024]    A “payment device” may include any suitable device capable of making a payment. For example, a payment device can include a card including a credit card, debit card, charge card, gift card, or any combination thereof. A payment device can be used in conjunction with a consumer device, as further defined below. 
         [0025]    A “payment processing network” (e.g., VisaNet™) may include data processing subsystems, networks, and operations used to support and deliver authorization services, exception file services, and clearing and settlement services. An exemplary payment processing network may include VisaNet™. Payment processing networks such as VisaNet™ are able to process credit card transactions, debit card transactions, and other types of commercial transactions. VisaNet™ in particular, includes a VIP system (Visa Integrated Payments system) which processes authorization requests and a Base II system which performs clearing and settlement services. 
         [0026]    An “authorization request message” may be an electronic message that is sent to an authorization system such as a payment processing network and/or an issuer computer to request authorization for a transaction. An authorization request message is an example of a transaction message. An authorization request message according to some embodiments may comply with ISO 8583, which is a standard for systems that exchange electronic transaction information associated with a payment made by a consumer using a payment device or a payment account. The authorization request message may comprise a primary account number (PAN), expiration date, service code, CVV and other data from a payment device. In some embodiments of the invention, an authorization request message may include a payment token (e.g., a substitute or pseudo account number), an expiration date, a token presentment mode, a token requestor identifier, an application cryptogram, and an assurance level data. The payment token may include a payment token issuer identifier that may be a substitute for a real issuer identifier for an issuer. For example, the real issuer identifier may be part of a BIN range associated with the issuer. An authorization request message may also comprise additional data elements including, by way of example only: a service code, a CW (card verification value), a dCW (dynamic card verification value), an expiration date, etc. 
         [0027]    An “authorization response message” may be an electronic message reply to an authorization request message generated by the authorization system. The authorization response message may include an authorization code, which may be a code that the authorization system returns in response to receiving an authorization request message (either directly or through the payment processing network). The authorization response message is received at the merchant&#39;s access device (e.g. POS terminal) and can indicate approval or disapproval of the transaction by the authorization system. 
         [0028]    An “access device” can include a device that allows for communication with a remote computer, and can include a device that enables a customer makes a payment to a merchant in exchange for goods or services. An access device can include hardware, software, or a combination thereof. Examples of access devices include point-of-sale (POS) terminals, mobile phones, tablet computers, laptop or desktop computers, etc. 
         [0029]    A “resource providing entity” can be any entity that provides resources during a transaction. For example, a resource providing entity can be a merchant, a venue operator, a building owner, a governmental entity, etc. 
         [0030]    A “wireless short range communication link” may include a communication link between two physical devices that does not utilize wires. Wireless short range communication links may utilize any suitable wireless communication technology including Bluetooth, Bluetooth Low Energy (BLE), Wi-Fi, Zig Bee, ultrasonic, a mixture of the aforementioned technologies, or other suitable protocols. The range of a short range communication link may generally be less than 100 feet. 
         [0031]    “Bluetooth low energy” (BLE) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group. Compared to Classic Bluetooth, BLE is intended to provide considerably reduced power consumption and cost while maintaining a similar communication range. A connection between two or more devices using BLE may be referred to as a BLE wireless connection. 
         [0032]    A “peripheral device” is any device defined as any auxiliary device such as that connects to and works with a computer in some way. A peripheral device according to embodiments of the invention may include devices that can establish wireless short range communication links and may use any of the above-noted wireless communication technologies. 
         [0033]    A “cryptogram” may refer to an encrypted representation of some information. A cryptogram can be used by a recipient to determine if the generator of the cryptogram is in possession of a proper key, for example, by encrypting the underlying information with a valid key, and comparing the result to the received cryptogram. 
         [0034]      FIG. 1  shows a block diagram of a communication device  120  in wireless communication with a peripheral device  140  associated with an access device  130 , in accordance with some embodiments of the invention. The access device  130  may be communicatively coupled to the peripheral device  140  through a wired or wireless connection. The access device  130  may be associated with a resource providing entity (e.g., a merchant) and present at a checkout area within a merchant store, for example. In some embodiments, the peripheral device  140  may be a BLE-enabled peripheral device configured to provide BLE wireless capability to the access device  130 . In some embodiments, the access device  130  may already have built-in BLE functionality and the peripheral device  140  may be incorporated into the access device  130 . 
         [0035]    The communication device  120  may a smartphone, tablet, mobile computer, or any other device capable of transmitting data to the peripheral device  140 . The communication device  120  may include software to facilitate a payment transaction, such as a digital wallet application. Further, the communication device  120  may include a Secure Element (SE) to securely store payment credentials associated with the user. Further, the communication device  120  may communicate, prior to a transaction, with a cloud service or a token service  110  in order to obtain payment data associated with the user. The cloud service or token service  110  may be associated with an issuer of the payment card associated with the user. The cloud service or token service  110  may be operated by one or more remotely located server computers. Further, the communication device  120  may communicate with the peripheral device  140  over BLE wireless link  160  (or other short range wireless communication link). The communication device  120  may have BLE functionality built-in to the device itself. 
         [0036]    In some implementations, the communication device  120  may be the central device and may function as the host in the BLE connection between the communication device  120  and the peripheral device  140 . In some implementations, the communication device  120  may be a tethered device. The communication device may also be referred to as a consumer device. 
         [0037]    At the time of a transaction, a user may approach the access device  130  located within, for example, a merchant store. The user may then initiate the transaction by interacting with his/her communication device  120  (e.g., by opening a digital wallet application or other payment application). The communication device  120  may then initiate a BLE wireless connection with the peripheral device  140  associated with the access device  130 . The wireless connection between the communication device  120  and the peripheral device  140  may be both secure and encrypted. In some embodiments, the peripheral device  140  may be continuously advertising its presence so that the communication device  120  can “scan” and discover available peripheral devices  140  within BLE range that may be suitable to establish a connection with. In some implementations, the communication device  120  may prompt the user to select from the peripheral devices  140  discovered by the communication device  120   
         [0038]    In some implementations, the peripheral device  140  may host the Generic Attribute Profile (GATT) database, which is part of the Bluetooth specification. 
         [0039]    After the BLE wireless connection has been established via the communication device  120  and the peripheral device  140 , the communication device  120  may display line item data for each item that is scanned at the access device  130 . For example, when a carton of milk is scanned at the access device  130 , the access device  130  may transmit (via peripheral device  140 ) the line item data (e.g., item information, quantity, price, tax information, etc.) to the communication device  120  via the BLE wireless connection. In turn, the communication device  120  may display the line item data in real-time to the user. Similarly, each subsequent item that is scanned may also be displayed on the communication device  120 . 
         [0040]    After all the desired items are scanned at the access device  130 , the user may be able to view line item data for all the items on the communication device  120  and elect to complete the transaction using the communication device  120 . The communication device  120  may transmit payment information to the access device  130  (via peripheral device  140 ) in order for the transaction to be authorized. Upon successful authorization of the transaction, the access device  130  may transmit (via peripheral device  140 ) a receipt for the transaction to the communication device  120 . The receipt may be displayed by the communication device  120 . Further details relating to the data transmitted over the BLE wireless connection are provided below. 
         [0041]      FIG. 2  is a diagram illustrating a data flow between a communication device  120  and a BLE peripheral device  140 , and an issuer computer  640  in accordance with some embodiments of the invention. 
         [0042]    At step s 1 , the peripheral device  140  (e.g., BLE equipped peripheral device) may “advertise” its presence by broadcasting a signal over a BLE channel. By advertising its presence, the peripheral device  140  may indicate that is ready to accept a BLE wireless connection from a communication device  120  in order to conduct a transaction at an access device  130  to which the peripheral device  140  is connected. The peripheral device  140  may advertise its presence by broadcasting the signal continuously or at predefined intervals (e.g., every 10 seconds). 
         [0043]    At step s 2 , after the peripheral device  140  advertises its presence, the communication device  120  may connect to the peripheral device  140 . In some embodiments, the communication device  120  may “scan” one or more BLE channels to discover which peripheral devices  140  are advertising their presence. Upon discovering one or more peripheral devices  140 , the communication device  120  may present a list of discovered peripheral devices  140  to the user. The user may select the appropriate peripheral device  140  that is associated with the access device  130  the user wishes to initiate the transaction with. In establishing the BLE connection with the peripheral device  140 , the communication device  120  may initiate a pairing procedure. The pairing procedure may include, but is not limited to, exchange of pairing information, authentication of the link, and distribution of keys. 
         [0044]    At step s 3 , after establishing the BLE connection with the peripheral device  140 , the communication device  120  may discover the available services on the peripheral device  140 . For example, the communication device  120  may use Bluetooth Service Discovery Protocol (SDP) to discover which services the peripheral device  140  supports. Upon determining which services the peripheral device  140  supports, the communication device  120  may elect which services to use for the BLE wireless connection. Accordingly, in step s 4 , the peripheral device  140  may provide the elected services and characteristics to the communication device  120 . 
         [0045]    At step s 5 , one or more items associated with the transaction may be scanned at the access device  130 . In this regard, the access device  130  may include a scanner such as a bar code scanner which can scan one or more items for purchase. Upon scanning each item at the access device  130 , the peripheral device  140  may transmit lime item data for each item to the communication device  120 , over the BLE wireless connection. Line item data may include, for example, item name, quantity, price, tax information, etc. Upon receiving the line item data from the peripheral device  140 , the communication device  120  may display the line item data to the user, such that the user can view in real-time the line item data for each item as it is scanned at the access device  130 . 
         [0046]    At step s 6 , after the line item data for each item scanned is sent to the communication device  120  in real-time by the access device  130 , the amount authorized may be sent from the access device  130  to the peripheral device  140 , and then to the communication device  120 . The amount authorized may indicate the total amount for the transaction that after all the items have been scanned by the access device  130 . In some embodiments of the invention, the peripheral device  140  may otherwise send a signal to the communication device  120  that the item scanning process is otherwise complete. In this regard, the total amount of the transaction could be sent from the peripheral device  140  to the communication device  120 . In either case, the signal may indicate that the access device  130  is now ready to receive payment data from the communication device  120 . 
         [0047]    At step s 7 , the communication device  120  may read various transaction related data from the peripheral device  140 , over the wireless BLE connection. The transaction related data can include, but is not limited to, a secondary amount associated with the transaction representing a cashback amount (AmountOther), Terminal Verification Results (TVR), currency code (CurrencyCode), date of the transaction (TransactionDate), type of the transaction (TransactionType), and a value to provide variability and uniqueness to the generation of a cryptogram (Unpredictable Number). The transaction data may include any other data part of the EMV (Europay Mastercard Visa) contactless specification. 
         [0048]    At step s 8 , after the communication devices  120  reads the various transaction related dada from the peripheral device  140 , the communication device  120  may send various transaction related data to the peripheral device  140 , over the wireless BLE connection. The transaction related data can include, but is not limited to, data elements of track 2 according to ISO/IEC 7813 (e.g., PAN, expiration, etc.) (Track2EquivalentData), Application Interchange Profile (AIP), Application Transaction Counter (ATC), Issuer Application Data (IAD), and Authorization Request Cryptogram (ARQC). The transaction data may include any other data part of the EMV contactless specification. Some of the transaction data elements may be obtained by the communication device  120  from the cloud service or token service  110 . For example, a payment token may be obtained (for every transaction, only once, or periodically) from the token service  110  instead of a PAN. 
         [0049]    At step s 9 , after the communication device  120  sends various transaction related data to the peripheral device  140 , the access device  130  (which is coupled to peripheral device  140 ) may forward the received transaction related data along with the final payment amount for the transaction to the issuer computer  650  for authorization. This may be sent in the form of an authorization request message. The data may be sent by the access device  130  over a traditional interconnected network, such as the Internet. For example, the access device  130  may send PaymentAmount, Track2EquivalentData, AIP, ATC, IAD, and ARQC to the issuer computer  650 . 
         [0050]    At step s 10 , after the access device  130  forwards the transaction related data along with the payment amount for the transaction to the issuer computer  650 , the issuer computer  650  may transmit approval of the transaction (in the form of an authorization response message) along with an Authorization Response Cryptogram (ARPC) to the access device  130 . 
         [0051]    At step s 11 , after receiving the authorization response message along with the ARPC, the access device  130  may, via peripheral device  140 , transmit the authorization response message and ARPC to the communication device  120  over the wireless BLE connection. 
         [0052]    At step s 12 , after the communication device  120  receives the authorization response message along with the ARPC, the communication device  120  may terminate the BLE wireless connection with the peripheral device  140 , as the transaction may be considered complete. 
         [0053]      FIG. 3  shows line item data being presented on a communication device  120  in real-time during a transaction, in accordance with some embodiments of the invention. As described above, during a transaction, line item data can be transmitted from the peripheral device  140  to the communication device  120  in real-time as each item is scanned at the access device  130 . The line item data can be transmitted over the established BLE wireless connection between the communication device  120  and the peripheral device  140 . Upon receiving the line item data for a particular item, the communication device  120  can immediately display the line item data to the user via display device  330 . The line item data can include, but is not limited to, item name  310 , item quantity  312 , and item price  314 . 
         [0054]    The list of items displayed on the display device  330  may be updated upon each scan of a subsequent item at the access device  130 . For example, in the figure, line item data for “Bread”, “Milk”, and “Cereal” is provided. The quantity and price information for each item is provided, and the grand total for all the items scanned is displayed in a checkout button  320  within the user interface shown on the display device  330 . In some implementations, an indicator or notification may be presented to the user that the total for the items has been calculated. 
         [0055]    Once all items desired for the transaction have been scanned at the access device  130 , the user may select the checkout button  320  to initiate payment for the scanned items. Upon selecting the checkout button  320  the communication device  120  may transmit payment data (described above) to the peripheral device  140  over the BLE wireless connection. Upon successful completion of the transaction, the display device  330  may display a receipt of the transaction for the user. 
         [0056]      FIG. 4  shows a block diagram of a communication device  120 , in accordance with some embodiments of the invention. Communication device  120  includes a processor  410 , a camera  420 , a display  330 , an input device  440 , a speaker  450 , a memory  460 , a Bluetooth interface  470 , a secure element  480 , and a computer-readable medium  490 . 
         [0057]    Processor  410  may be any suitable processor operable to carry out instructions on the communication device  120 . The processor  410  may comprise a CPU that comprises at least one high-speed data processor adequate to execute program components for executing user and/or system-generated requests. The CPU may be a microprocessor such as AMD&#39;s Athlon, Duron and/or Opteron; IBM and/or Motorola&#39;s PowerPC; IBM&#39;s and Sony&#39;s Cell processor; Intel&#39;s Core, Atom, Celeron, Itanium, Pentium, Xeon, and/or XScale; and/or the like, processor(s). The processor  410  is coupled to other units of the communication device  120  including camera  420 , display  330 , input device  440 , speaker  450 , memory  460 , and computer-readable medium  470 . 
         [0058]    Camera  420  may be configured to capture one or more images via a lens located on the body of communication device  120 . The captured images may be still images or video images. The camera  420  may include a CMOS image sensor to capture the images. 
         [0059]    Display  330  may be any device that displays information to a user. Examples may include an LCD screen, CRT monitor, or seven-segment display. 
         [0060]    Input device  440  may be any device that accepts input from a user. Examples may include a keyboard, keypad, mouse, or microphone. In the case of a microphone, the microphone may be any device that converts sound to an electric signal. In some embodiments, the microphone may be used to capture one or more voice segments from a user for user authentication. 
         [0061]    Speaker  450  may be any device that outputs sound to a user. Examples may include a built-in speaker or any other device that produces sound in response to an electrical audio signal. 
         [0062]    Memory  460  may be any magnetic, electronic, or optical memory. It can be appreciated that memory  460  may include any number of memory modules. An example of memory  460  may be dynamic random access memory (DRAM). 
         [0063]    Bluetooth interface  470  may be any interface or chipset that is operable for fundamental Bluetooth tasks, such as initiating device discovery, querying a list of bonded (paired) devices, instantiating a Bluetooth device using a known MAC address, creating a Bluetooth Server Socket to listen for connection requests from other devices, and start a scan for Bluetooth LE devices. The Bluetooth interface may transmit and receive Bluetooth wireless signals using an antenna built-in to the Bluetooth interface  470  or may interface with an Bluetooth antenna external (not shown) to the Bluetooth interface  470 . 
         [0064]    Secure element  480  can be a secure memory and execution environment. The secure element  480  may be a dynamic environment in which application code and application data can be securely stored and administered and in which secure execution of applications occur. The secure element  480  may reside in highly secure crypto chip (e.g., a smart card chip). The secure element  480  could be implemented either by a separate secure smart card chip, in the Subscriber Identity Module/Universal Integrated Circuit Card (SIM/UICC) (which is used by GSM mobile phone operators to authenticate subscribers on their networks and maintain personalized subscriber information and applications), or in an SD card that can be inserted in the communication device  120 . In some embodiments, the payment information transmitted from the communication device  120  to the peripheral device  140  over the BLE wireless connection can be stored within the secure element  480 . In some implementations, software-based host card emulation (HCE) may be used instead of a hardware-based secure element. 
         [0065]    Computer-readable medium  490  may be any magnetic, electronic, optical, or other computer-readable storage medium. Computer-readable storage medium  490  includes Bluetooth module  492 , line item display module  494 , and transaction data module  496 .

The wireless communication module  492  can control various aspects of the wireless communication interface  470  hardware. In another example, the wireless communication module  492  may forward line item data received from peripheral device  140 , via wireless communication interface  470 , to the line item display module  494 . 
         [0067]    The line item display module  494  may comprise code, that when executed by processor  410 , can cause the display  330  to display line item data received by communication device  120  via the wireless communication interface  470 . The line item display module  494  may generate the user interface for displaying the line item data within the display  330 . 
         [0068]    Transaction data module  496  may comprise code, that when executed by processor  410 , can cause the transaction data module  496  to transmit and receive transaction data, via wireless communication interface  470 , to the peripheral device  140 . The transaction data can include any data relevant to processing and authorizing the transaction. For example, the transaction data can include payment credentials associated with the user participating in the transaction. 
         [0069]      FIG. 5  shows a block diagram of a wireless communication peripheral device  140 , in accordance with some embodiments of the invention. Peripheral device  140  includes an input/output interface  510 , a memory  520 , a processor  530 , Bluetooth interface  540 , and a computer-readable medium  550 . In some embodiments, the peripheral device  140  may be coupled to the access device  130 . 
         [0070]    The input/output (I/O) interface  510  is configured to receive and transmit data. For example, the I/O interface  510  may receive data transmitted over channels other than, for example, aBLE wireless connection. The I/O interface  510  may accept input from an input device such as, but not limited to, a keyboard, keypad, or mouse. Further, the I/O interface may display output on a display device. 
         [0071]    Memory  520  may be any magnetic, electronic, or optical memory. It can be appreciated that memory  520  may include any number of memory modules. An example of memory  520  may be dynamic random access memory (DRAM). 
         [0072]    Processor  530  may be any general-purpose processor operable to carry out instructions on the peripheral device  140 . The processor  530  is coupled to other units of the peripheral device  140  including input/output interface  510 , memory  520 , Bluetooth interface  540 , and computer-readable medium  550 . 
         [0073]    Computer-readable medium  550  may be any magnetic, electronic, optical, or other computer-readable storage medium. Computer-readable storage medium  550  includes Bluetooth module  552 , line item data module  554 , and transaction data module  556 . 
         [0074]    Wireless communication module  552  may comprise code, that when executed by processor  530 , can cause the wireless communication interface  540  to perform various functions. For example, the wireless communication module  552  can instruct the wireless communication interface  540  to perform a broadcasting a wireless signal in order to “advertise” the peripheral device&#39;s  140  presence. The wireless communication module  552  can control various aspects of the wireless communication interface  540  hardware. In another example, the wireless communication module  552  may transmit, via Bluetooth interface  540 , line item data received from the line item data module  554  to the communication device  120 . 
         [0075]    Transaction data module  556  may comprise code, that when executed by processor  530 , can cause the wireless communication interface  540  to transmit and receive transaction data, via wireless communication interface  540 , to the communication device  120 . Additionally, the transaction data module  556  can cause the input/output interface to transmit the transaction data to the access device, which may then generate and send an authorization request to an issuer. The transaction data can include any data relevant to processing and authorizing the transaction. For example, the transaction data can include payment credentials associated with the user participating in the transaction. 
         [0076]      FIG. 6  shows a block diagram of a more detailed view of a transaction processing system  600 . The system  500  may include a communication device  120 , an access device  130 , a peripheral device  140 , a merchant computer  635 , an acquirer computer  630 , a payment processing network computer  640 , and an issuer computer  650 . In some implementations, different entities in  FIG. 6  may communicate with each other using one or more interconnected communication networks  660  such as the Internet, a cellular network, a TCP/IP network or any other suitable communication network. Note that one or more entities in the system  600  may be associated with a computer apparatus that may be implemented using some of the components as described with reference to  FIGS. 4 and 5 . 
         [0077]    The communication device  120  may be associated with a payment account of a user. In some implementations, the communication device  120  may be a mobile device such as a mobile phone, a tablet, a PDA, a notebook, a key fob or any suitable mobile device. In some embodiments, the communication device  120  may be a wearable device such as, but not limited to, a smart watch, a fitness band, an ankle bracelet, a ring, earrings, etc. For example, the communication device  120  may include a virtual wallet or a payment application that may be associated with one or more payment accounts of the user. In some implementations, the communication device  120  may be capable of communicating with the access device  130  using a wireless data protocol such as Wi-Fi™ or Bluetooth™. For example, the communication device  120  may interact with the access device  130  by establishing a connection with the access device  130  using a wireless data protocol. As noted above, the communication device  120  may also communicate with a peripheral device  140  which may be coupled to the access device  130 . 
         [0078]    The access device  130  may be an access point to a transaction processing system that may comprise the acquirer computer  630 , the payment processing network computer  640 , and the issuer computer  650 . In some implementations, the access device  130  may be associated with or operated by the merchant computer  635 . For example, the access device  130  may be a point of sale device that may include a contactless reader, an electronic cash register, a display device, etc. In some implementations, the access device  130  may be configured to transmit information pertaining to one or more purchased items at a merchant  635  to an acquirer  630  or payment processing network  640 . In some implementations, the access device  130  may be a personal computer that may be used by the user to initiate a transaction with the merchant computer  635  (e.g., an online transaction). In some implementations, the access device  130  may be configured to interface with a peripheral device  140  to communicate with a communication device  120  using a BLE wireless connection. 
         [0079]    The acquirer computer  630  may be operated by an acquirer. The acquirer is typically a system for an entity (e.g., a bank) that has a business relationship with a particular merchant, a wallet provider or another entity. The acquirer computer  630  may be communicatively coupled to the merchant computer  635  and the payment processing network  640  and may issue and manage a financial account for the merchant. The acquirer computer  630  may be configured to route the authorization request for a transaction to the issuer computer  650  via the payment processing network computer  640  and route an authorization response received via the payment processing network computer  640  to the merchant computer  635 . 
         [0080]    The payment processing network computer  640  may be configured to provide authorization services, and clearing and settlement services for payment transactions. The payment processing network computer  640  may include data processing subsystems, wired or wireless networks, including the internet. An example of the payment processing network computer  640  includes VisaNet 198  , operated by Visa®. Payment processing networks such as VisaNet™ are able to process credit card transactions, debit card transactions, and other types of commercial transactions. VisaNet™, in particular includes a Visa Integrated Payments (VIP) system which processes authorization requests and a Base II system which performs clearing and settlement services. The payment processing network computer  640  may include a server computer. In some implementations, the payment processing network computer  640  may forward an authorization request received from the acquirer computer  630  to the issuer computer  650  via a communication channel. The payment processing network computer  640  may further forward an authorization response message received from the issuer computer  650  to the acquirer computer  630 . 
         [0081]    The issuer computer  650  may represent an account issuer and/or an issuer processor. Typically, the issuer computer  650  may be associated with a business entity (e.g., a bank) that may have issued an account and/or payment card (e.g., credit account, debit account, etc.) for payment transactions. In some implementations, the business entity (bank) associated with the issuer computer  650  may also function as an acquirer (e.g., the acquirer computer  630 ). 
         [0082]    As noted above, in some embodiments, the access device  130  may be coupled to a peripheral device  140  that provides BLE wireless connection functionality. The communication device  120  and access device  130  may communicate via a BLE wireless connection facilitated by the peripheral device  140 . After transmitting and receiving various transaction related data between the communication device  120  and the peripheral device  140 , the access device  130  may generate an authorization request message which may pass to the issuer  650  via the acquirer  630  and the payment processing network  640 . The issuer  650  may then authorize the transaction, and may return an authorization response message back to the acess device  130  via the payment processing network  640  and the acquirer  630 . At the end of the day or any other suitable time period, a clearing and settlement process may take place. 
         [0083]    The various participants and elements described herein with reference to  FIGS. 1-6  may operate one or more computer apparatuses to facilitate the functions described herein. Any of the elements in  FIGS. 1-6 , including any servers or databases, may use any suitable number of subsystems to facilitate the functions described herein. 
         [0084]    Examples of such subsystems or components are shown in  FIG. 7 . The subsystems shown in  FIG. 7  are interconnected via a system bus  775 . Additional subsystems such as a printer  703 , keyboard  706 , fixed disk  707  (or other memory comprising computer readable media), monitor  709 , which is coupled to display adapter  704 , and others are shown. Peripherals and input/output (I/O) devices, which couple to I/O controller  700  (which can be a processor or other suitable controller), can be connected to the computer system by any number of means known in the art, such as serial port  705 . For example, serial port  705  or external interface  708  can be used to connect the computer apparatus to a wide area network such as the Internet, a mouse input device, or a scanner. The interconnection via system bus allows the central processor  702  to communicate with each subsystem and to control the execution of instructions from system memory  701  or the fixed disk  707 , as well as the exchange of information between subsystems. The system memory  701  and/or the fixed disk  707  may embody a computer readable medium. 
         [0085]    Embodiments of the invention provide a number of advantages. For example, in embodiments of the inveniton, a single connection session between a communication device and an access device, via a peripheral device, may allow the communication device to both receive information as a transaction is in progress and also transmit credential information to conduct a payment transaction. Conventionally, this process may involve multiple steps, however, embodiments of the invention make transaction processing at a point of sale much simpler and efficient. 
         [0086]    Any of the software components or functions described in this application, may be implemented as software code to be executed by a processor using any suitable computer language such as, for example, Java, C++ or Perl using, for example, conventional or object-oriented techniques. The software code may be stored as a series of instructions, or commands on a computer readable medium, such as a random access memory (RAM), a read only memory (ROM), a magnetic medium such as a hard-drive or a floppy disk, or an optical medium such as a CD-ROM. Any such computer readable medium may reside on or within a single computational apparatus, and may be present on or within different computational apparatuses within a system or network. 
         [0087]    While the above description discusses using BLE to facilitate a transaction, other medium-range wireless communication protocols may also be used. For example, Wi-Fi may be used to transfer transaction information between the communication device and the peripheral device. Additionally, a mix of different medium-range wireless communication protocols may also be used. For example, a mix of NFC and BLE may be used to transfer transaction information between the communication device and the peripheral device, where certain communications may be completed over NFC and certain communications may be completed over BLE. 
         [0088]    The above description is illustrative and is not restrictive. Many variations of the invention will become apparent to those skilled in the art upon review of the disclosure. The scope of the invention should, therefore, be determined not with reference to the above description, but instead should be determined with reference to the pending claims along with their full scope or equivalents. 
         [0089]    One or more features from any embodiment may be combined with one or more features of any other embodiment without departing from the scope of the invention.
