8. The method of claim 6 , wherein the peripheral device is a BLE enabled device.

9. The method of claim 6 , wherein the point of sale device processes the transaction based at least in part on the transmitted payment data.

10. The method of claim 6 , further comprising:

transmitting, by the peripheral device and to the communication device, item level data associated with a second item being processed by the point of sale device, wherein the communication device displays the item level data associated with the second item.

11. A communication device, comprising:

a processor; and

a computer readable medium coupled to the processor, the computer readable medium comprising code, executable by the processor, for implementing a method comprising:

discovering, via a wireless short-range communication channel, a number of available peripheral devices, each of the number of available peripheral devices linked to a different point of sale device and continuously advertising its presence;

upon receiving a selection of a peripheral device associated with a point of sale device from the number of available peripheral devices, establishing a wireless-short range communication link with the peripheral device, wherein the communication device is a mobile device that is executing a payment application, and wherein the point of sale device that is located within a merchant store;

receiving from the peripheral device, item level data associated with an item for purchase that as the item for purchase is being processed at the point of sale device;

displaying, on a display on the communication device, the item level data associated with the item for purchase;

receiving, by the communication device and from the peripheral device, an unpredictable number to provide variability and uniqueness to generation of a cryptogram;

generating, by the communication device, an authorization request cryptogram using the unpredictable number; and

transmitting, via the payment application that is executing on the communication device, payment data to the point of sale device, wherein the payment data comprises the authorization request cryptogram.

12. The communication device of claim 11 , wherein the wireless-short range communication link is a Bluetooth low energy (BLE) communication link.

13. The communication device of claim 12 , wherein the peripheral device is a BLE enabled device.

14. The communication device of claim 11 , wherein the point of sale device processes a transaction based at least in part on the transmitted payment data.

15. The communication device of claim 11 , wherein the method further comprises:

receiving from the peripheral device, item level data associated with a second item being processed by the point of sale device; and

displaying, on the display, the item level data associated with the second item.

16. A system comprising:

point of sale device; and

a peripheral device, wherein the peripheral device comprises:

a processor, and

a computer readable medium coupled to the processor, the computer readable medium comprising code, executable by the processor, for implementing a method comprising

continuosly advertising, by the peripheral device linked to the point of sale device, an availability of the point of sale device;

upon receiving a communication from a communication device via a wireless short-range communication channel, establishing a wireless-short range communication link to the communication device, wherein the communication device is a mobile device that is executing a payment application, and wherein the point of sale device is located within a merchant store;
