Communicating via near field communications

A computer program product, comprising:

• a non-transitory computer-readable storage device having computer-executable
• program instructions embodied thereon that when executed by a computer cause the computer to communicate via near field communication (NFC) between NFC readers and NFC-enabled applications available on NFC-enabled user computing devices, the computer-executable program instructions comprising:
• computer-executable program instructions to receive, from an NFC reader by an NFC-enabled user computing device, a first selection command for an NFC application identifier (AID) proxy of the user computing device;
• computer-executable program instructions to receive, from the reader by the selected proxy, a query directed to an availability of an NFC-enabled application on the user computing device, the query comprising an argument identifying the application by a domain name;
• computer-executable program instructions to determine, by the proxy, whether the received domain name corresponds to an AID of an application available on the user computing device;
• computer-executable program instructions, for a received domain name determined to correspond to an AID of an application available on the user computing device, to transmit, to the NFC reader by the user computing device, a response indicating the AID of the application corresponding to the received domain name;
• computer-executable program instructions to receive, from the reader by the user computing device via an NFC channel, a selection command for the transmitted AID;
• and
• computer-executable program instructions to communicate, by the application corresponding to the selected AID via the channel, in an NFC application protocol data unit (APDU) communication session with the reader.

A system to communicate via near field communication (NFC) between NFC readers and NFC-enabled applications available on NFC-enabled user computing devices, comprising:

• a storage device;
• and
• a processor communicatively coupled to the storage device, wherein the processor executes application code instructions that are stored in the storage device to cause the system to:
• receive, from an NFC reader by an NFC-enabled user computing device, a first selection of an NFC application identifier (AID) proxy of the user computing device;
• receive, from the reader by the selected proxy, a query directed to the availability of an NFC-enabled application on the user computing device, the query comprising an argument identifying the application by a domain name;
• determine, by the proxy, whether the received domain name corresponds to an AID of an application available on the user computing device;
• for a received domain name determined to correspond to an AID of an application available on the user computing device, transmit, to the NFC reader by the user computing device, a response indicating the AID of the application corresponding to the received domain name;
• receive, from the reader by the user computing device via an NFC channel, a selection of the transmitted AID;
• and
• communicate, by the application corresponding to the selected AID via the channel, in an NFC application protocol data unit (APDU) communication session with the reader in response to the received selection of the transmitted AID.
