Abstract

The invention discloses a digital currency transaction method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the following steps of: when a first transaction terminal is in a power-on state, sending an input power-free transaction parameter to a digital currency card application device running in an SIM (Subscriber Identity Module) card of the first transaction terminal through a digital currency application program, and setting the power-free transaction parameter by the digital currency card application device, the digital currency application program is arranged in the first transaction terminal; after the first transaction terminal is powered off, when a transaction request sent by the second transaction terminal is received, the first transaction terminal executes digital currency transaction with the second transaction terminal through the digital currency card application device according to the power-off transaction parameters. According to the embodiment, the mobile intelligent terminal based on the SIM card can carry out digital currency transactions such as no-power payment or no-power collection.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a digital currency transaction method and device. Background technique [0002] NFC (Near Field Communication, Chinese full name is near field communication technology) is developed on the basis of non-contact radio frequency identification (RFID) technology combined with wireless interconnection technology. As an important wireless communication technology, NFC provides a non-touch wireless communication solution, that is, data communication can be completed when two devices are close to each other, allowing consumers to exchange information, access and services more quickly and intuitively. Features such as security and low power consumption have become the main technologies used in short-distance communication. [0003] At present, with the rapid development of mobile smart terminals (including smart phones, smart watches, and smart POS (Point of sales, the ful...
