Abstract

A reader device may include a midrange wireless transceiver, a controller coupled to the midrange wireless transceiver, and a memory coupled to the controller. The memory may store executable code, which when executed by the controller, causes the reader device to implement various operations including maintaining a transaction service attributes database in the memory. The operations may also include broadcasting a beacon including a transaction service indicator at a periodic interval using the midrange wireless transceiver, receiving a connection request from a communication device, and establishing a wireless connection with the communication device. The operations may further include performing an application selection process with the communication device, performing application data processing with the communication device, and performing authorization request processing for the communication device.

First claim

What is claimed is:

1. A system comprising:
a plurality of access terminals communicatively coupled to a plurality of reader devices, wherein each of the plurality of access terminals are communicatively coupled to each of the plurality of reader devices, wherein the number of the plurality of reader devices is less than the number of the plurality of access terminals, and wherein the plurality of reader devices are shared amongst the plurality of access terminals; and
the plurality of reader devices, each reader device including:
a midrange wireless transceiver;
a controller coupled to the midrange wireless transceiver; and
a memory coupled to the controller, the memory storing executable code, which when executed by the controller, causes the controller to perform operations including:
maintaining transaction service attributes at the reader device, the transaction service attributes including a set of transaction service characteristics including a selected application identifier characteristic, an application data characteristic, and a transaction amount confirmation characteristic, wherein the set of transaction service characteristics are transient;
broadcasting a beacon at a periodic interval using the midrange wireless transceiver, the beacon including a transaction service indicator, each reader device using the same transaction service indicator, and wherein only one of the plurality of reader devices at a time performs the broadcasting the beacon at the periodic interval;
receiving a connection request from a communication device via the midrange wireless transceiver;
in response to receiving the connection request from the communication device, establishing a wireless connection with the communication device via the midrange wireless transceiver and ending the broadcasting the beacon, wherein, after the wireless connection with the communication device is established, a next reader device from the plurality of reader devices starts broadcasting the beacon;
performing an application selection process with the communication device by updating the selected application identifier characteristic in the transaction service attributes based on file control information received from the communication device via the midrange wireless transceiver;
performing application data processing with the communication device by updating the application data characteristic and the transaction amount confirmation characteristic in the transaction service attributes with application data received from the communication device via the midrange wireless transceiver, the application data including an application cryptogram; and
performing authorization request processing for the communication device, the authorization request processing including generating an authorization request message based on the application data in the transaction service attributes and sending, using one of the plurality of access terminals, the authorization request message to a transaction processing system.

2. The system of claim 1 , wherein the application selection process includes:
receiving system file control information from the communication device;
updating a system file control information characteristic in the transaction service attributes based on the received system file control information;
selecting an application identifier based on the system file control information; and
updating the selected application identifier characteristic in the transaction service attributes with the selected application identifier.

3. The system of claim 2 , wherein the application selection process further includes:
notifying the communication device of the selected application identifier characteristic;
receiving application file control information associated with the selected application identifier from the communication device; and
updating an application file control information characteristic and a processing options characteristic in the transaction service attributes based on the received application file control information.

4. The system of claim 3 , wherein the application data processing includes:
notifying the communication device of the processing options characteristic;
receiving first application data from the communication device;
in response to receiving the first application data, updating a first application data characteristic and the transaction amount confirmation characteristic in the transaction service attributes;
notifying the communication device of the transaction amount confirmation;
receiving second application data from the communication device to be written into the transaction service attributes; and
in response to receiving the second application data, updating a second application data characteristic in the transaction service attributes.

5. The system of claim 4 , wherein the first application data includes an application transaction counter value.

6. The system of claim 1 , wherein the application cryptogram is an encrypted combination of a transaction amount and an unpredictable number and a token.

7. The system of claim 4 , wherein the authorization request processing includes:
wherein the sending of the authorization request message includes sending at least a portion of the first application data and a portion of the second application data;
receiving, using the one of the plurality of access terminals, an authorization response message from the transaction processing system;
parsing the authorization response message;
determining a transaction result based on the parsing of the authorization response message;
updating a transaction result characteristic in the transaction service attributes with the transaction result; and
notifying the communication device of the transaction result.

8. The system of claim 1 , wherein the operations further include:
receiving a scan response request from the communication device; and
sending scan response data to the communication device, the scan response data including a device name of the reader device.

9. The system of claim 1 , further comprising:
a proximity wireless interface, wherein the operations further include:
initiating a second transaction via the midrange wireless transceiver with a second communication device;
prior to completing the second transaction, receiving a communication on the proximity wireless interface from the second communication device;
purging data received via the midrange wireless transceiver from the second communication device;
disabling the midrange wireless transceiver;
completing the second transaction using the proximity wireless interface; and
re-enabling the midrange wireless transceiver after completing the second transaction.

10. The system of claim 8 , wherein the device name of the reader device is the same for each of the plurality of reader devices.

11. The system of claim 10 , wherein the device name of the reader device is a merchant name of a merchant, and wherein each of the plurality of access terminals are associated with the merchant.

12. The system of claim 1 , wherein the transaction service indicator is a universally unique identifier (UUID).

13. A method comprising:
maintaining, by a reader device in a system including a plurality of reader devices communicatively coupled to a plurality of access terminals, transaction service attributes at the reader device, the transaction service attributes including a set of transaction service characteristics including a selected application identifier characteristic, an application data characteristic, and a transaction amount confirmation characteristic, wherein the
