Host-formatted select proximity payment system environment response

摘要

Informing near field communication (NFC) payment readers of NFC target device payment application availability. A payment application executing under a host operating system of an NFC target device formats a SELECT proximity payment system environment (PPSE) RESPONSE as one or more NFC Application Protocol Data Units (APDUs). The SELECT PPSE RESPONSE is formatted to respond to a SELECT PPSE command from an NFC payment reader. The SELECT PPSE RESPONSE includes a list of one or more Application Identifiers (AIDs) corresponding to one or more payment options available on the NFC target device. The payment application communicates the formatted SELECT PPSE RESPONSE to a PPSE applet executing on the NFC target device. The PPSE applet receives a SELECT PPSE command from an NFC payment reader. The PPSE applet communicates the SELECT PPSE RESPONSE to the NFC payment reader, in response to receiving the SELECT PPSE command from the NFC payment reader.
