Abstract

Disclosed are a near field communication method and terminal, used for solving the defect existing in the prior art that only a default HCE application can respond to a PPSE selection instruction. The method is applied to a first terminal supporting near field communication (NFC), wherein the first terminal comprises M payment applications, and M is greater than 1. The method comprises: the first terminal receiving a first instruction sent by a second terminal; and the first terminal sending to the second terminal a response message for responding to the first instruction, wherein the response message comprises N application identifiers (AIDs), the N AIDs are all the AIDs comprised by the M payment applications, each of the payment applications comprises at least one AID, and the M payment applications comprise a host card emulation (HCE) application or the M payment applications comprise the HCE application and a card application.

Description

technical field [0001] The embodiment of the present invention relates to the field of mobile payment, in particular to a near field communication payment method and terminal. Background technique [0002] At present, Near Field Communication (English full name: Near Field Communication, abbreviation: NFC) payment is a trend of the times. For example: through the card simulation technology, the payment application installed on the NFC terminal communicates with the card reader or the sales terminal (English full name: point of sale, abbreviation: POS) and completes the payment transaction. The payment application can be a card application or Host Card Emulation (English full name: Host Card Emulation or Host-based Card Emulation, abbreviation: HCE) application. [0003] like figure 1 As shown, the traditional card simulation technology is realized through the security element (English full name: SecureElement, abbreviation: SE) in the NFC terminal. The card application tha...
