Electronic payment device for mobile equipment

Abstract

The invention relates to an electronic payment device for mobile equipment. The electronic payment device comprises a magnetic card reading module, a fingerprint acquisition module, a fingerprint verification module, a storage module, a safe module, an audio plug, a modem module, a chip, a casing and a power supply, wherein the safe module is used for encrypting data, the audio plug is provided with an MIC pole and a sound track pole, the modem module is used for converting digital data to be sent to the mobile equipment into analog data, and the chip comprises a processing chip and a controlling chip. If the fingerprint verification module verifies an identity to pass, the control chip can control the magnetic card reading module to read magnetic card information to control the safe module to encrypt fingerprint characteristics and the magnetic card information and control the modem module to convert data, and the data are sent to the mobile equipment through the audio plug. According to the invention, electronic payment safety and security are improved through fingerprints verifying and safe module encryption. By means of the audio plug, adaptability of the electronic payment device is improved.

Description

technical field [0001] The invention relates to the field of electronic payment security, in particular to a device for realizing electronic payment of a mobile device in cooperation with a built-in electronic payment application client of the mobile device. Background technique [0002] Existing electronic payment is usually carried out by simply entering the bank account number and payment password on the bank payment webpage.
