Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 1 As shown, it is a block diagram of the radio frequency smart card module of the present invention, wherein the SIM module completes traditional telecommunication services, and the on-chip operating system completes the management of the carried business functions and power consumption. The present invention provides a radio frequency smart card, including an MCU. The radio frequency smart card also includes a timer. The MCU enters the shutdown mode after setting the timer wake-up function, and wakes up the computer in the shutdown mode when the timer expires. MCU. When the radio frequency module receives data, it outputs a changed voltage signal, and the changed voltage signal is used as an external interrupt signal of the MCU to wake up the MCU. Wherein, the timer is integrated on the MCU or on the RF module...

Abstract

The invention provides a radio frequency smart card, which comprises a micro control unit (MCU), a radio frequency module and a timer, wherein the timer is used for awakening the MCU in a suspended state at preset time or in a preset mode; and the radio frequency module outputs a varied voltage signal when receiving data, and the varied voltage signal serves as an external interrupt signal of the MCU to awaken the MCU. The invention also provides a method for controlling the radio frequency smart card. According to the method, standby power consumption can be lowered by software control over the receiving time of each radio frequency channel and the sleep mode time of the radio frequency smart card.

Description

technical field [0001] The invention relates to the smart card technology in the field of communication technology, in particular to the smart card technology with radio frequency function in the field of mobile payment. Background technique [0002] With the development of wireless communication technology, especially the development of short-distance communication technology, mobile payment near-distance wireless communication technology has been widely used in social life. The carrier that can realize this application technology is a radio frequency smart card and a reader module that can identify the card. [0003] The radio frequency smart card is composed of a radio frequency module + SIM module, which is consistent with the traditional SIM card in appearance. The SIM module completes traditional telecommunication services, and the radio frequency smart card can complete new business functions, such as access control cards, credit cards, small payment cards, time atte...
