Abstract

The invention discloses a portable illegal swiping prevention device based on signal shielding. The portable illegal swiping prevention device comprises an illegal swiping recognition module, a signalshielding module and a signal interference module which are connected with a main control module. The main control module is used for analyzing and processing signals sent by the unauthorized swipingidentification module, the signal shielding module and the signal interference module; the unauthorized swiping identification module is used for identifying an electromagnetic signal emitted by theunauthorized swiping device and sending a generated induction signal to the main control module; the signal shielding module is used for shielding the electromagnetic environment where the IC card islocated, so that the IC card cannot send out own information; and the signal interference module is used for transmitting an electromagnetic interference signal to perform electromagnetic interferenceon the unauthorized swiping device, so that the unauthorized swiping device reads wrong electromagnetic information. The IC card can be prevented from being stolen and swiped in a short distance, andthe IC card is portable and is convenient for modern people to carry when going out.

Description

technical field [0001] The present application relates to the field of IC card anti-theft technology, in particular to a portable anti-theft swiping device based on signal shielding. Background technique [0002] In the process of implementing QuickPass with a contactless IC card, since the cardholder does not need to enter the password, there is a risk of being stolen. In addition, the current near field communication (NearField Communication, NFC) technology has also been greatly developed, resulting in many terminal devices having the NFC function. This has just increased the possibility that criminals utilize the mobile terminal equipment to steal the IC or obtain the information risk in the IC card. In recent years, incidents of stealing ICs have also been frequently reported, causing great economic losses. [0003] At present, cards and wallets are the main physical solutions for IC card theft. The products of this type of solution are limited in form, and the distan...
