Card device having fingerprint identifying function, and corresponding charging device thereof

Abstract

The invention provides a card device having a fingerprint identifying function, and a corresponding charging device thereof. A fingerprint acquisition unit acquires a fingerprint image of a finger pressed on the fingerprint acquisition unit; a fingerprint identifying and processing unit stores and compares the acquired fingerprint, and selectively activates a control signal output unit according to a comparison result; the control signal output unit receives an activation instruction and outputs a control signal to the outside; the card device also comprises a chargeable battery adapted to the thickness of the card device and used for supplying power to the fingerprint acquisition unit, the fingerprint identifying and processing unit and the control information output unit; and the chargeable battery has or is connected with a smart card universal contact interface module used as a charging interface. The combination of a fingerprint identification system and a traditional card device is realized, the safety of the system is guaranteed, and an active battery power supply system working in an active working mode is adopted, so the card device has improved reliability and stability, allows a user to charge in a plug-in manner, and is simple and fast.

Description

technical field [0001] The invention relates to information security control technology, including but not limited to the fields of finance, security (access control), information security, remote control, etc., and specifically relates to a card device with a fingerprint recognition function. Background technique [0002] Traditional radio frequency identification (RFID) card technology has been in the market for decades, especially in the field of security and access control. But for a long time, it is difficult to solve the problem of embezzlement and fraud, which reduces its security and affects the accurate operation of the system. [0003] The most common application of existing RFID card technology is access control. Register a radio frequency identification card card information in the access control system in advance, when the user enters the control area, swipe the radio frequency identification card (contact or non-contact mode) on the access control reader, and ...

AI Technical Summary

Problems solved by technology

[0006] The existing RFID card technology with fingerprint identification, due to technical limitations, adopts a passive system, that is to say, they need to pass passively from an RFID card reader outside the system, or through a USB cable, Obtain power from the outside world by wireless (coil induction) or wired (USB interface, etc.), the way to obtain it is either unstable because of wireless acquisition, or inconvenient because of the connection method (requires external equipment or power supply)
