Mobile phone film card used for radio frequency-subscriber identity module (RF-SIM) card mobile phone payment

Abstract

The invention relates to a mobile phone film card used for a radio frequency-subscriber identity module (RF-SIM) card mobile phone payment. The mobile phone film card is arranged on the back shell of a mobile phone terminal inserted with an RF-SIM card is inserted in a pasting way; the mobile phone film card comprises an SIM security chip and two radio frequency identification (RFID) chips which are communicated with the SIM security chip through communication interfaces; and the two RFID chips are respectively communicated with a point-of-sale (POS) transaction terminal and the RF-SIM card in a mobile phone through RFID interfaces. The mobile phone film card has the advantages that: the mobile phone payment can be performed no matter whether the radio-frequency frequency of the RF-SIM card and the radio-frequency frequency of the POS transaction terminal are the same or not; because only a film card needs to be arranged on the back shell of the mobile phone, the cost is low, the film card is rapid and convenient to arrange; the film card can be used normally by only pasting on the back shell of the mobile phone; and the mobile phone film card is convenient to extend the application or the function of the RF-SIM card.

Description

technical field [0001] The invention relates to the technical field of mobile phone payment, in particular to a mobile phone film card applied to RF-SIM card mobile phone payment. Background technique [0002] At present, the solutions of mobile payment function mainly include RF-SIM and NFC technology. Each of these two technologies has different advantages and disadvantages: [0003] 1) RF-SIM uses 2.4GHZ radio frequency, which has strong penetration and does not need to replace the mobile phone, but it is not compatible with the 13.56MHZ radio frequency of most POS transaction terminals at present, so all POS transaction terminals need to be replaced; [0004] 2) NFC uses 13.56MHZ radio frequency, which is compatible with most existing POS transaction terminals on the market, but the penetrability is weak, and it is not easy to penetrate the back shell of the mobile phone, so the mobile phone needs to be replaced. Contents of the invention [0005] For the deficiencie...
