What are the RFID Blocking Items?

Firstly, lets explain RFID. RFID is the abbreviation of radio frequency identification.


RFID Principle

Its principle is that the reader and the tag communicate with each other in a non-contact way, so as to achieve the goal of identifying the target. RFID is widely used, such as animal chip, car chip anti-theft device, access control, parking lot control, production line automation and material management.


A complete RFID system is composed of reader, electronic tag, so-called transponder and application software system. Its working principle is that the reader transmits a specific frequency of radio wave energy to drive the circuit to send out the internal data. At this time, the reader will receive and interpret the data in order and send it to the application program for corresponding processing.


The basic working principle of RFID technology is not complicated: after the tag enters the reader, it receives the RF signal sent by the reader, and sends the product information (passive tag, passive tag or passive tag) stored in the chip with the energy obtained by the induced current, or the tag actively sends the signal of a certain frequency (active tag, active tag or active tag), and the reader reads after the information is taken and decoded, it is sent to the central information system for relevant data processing.  


RFID Anti-Theft Wallet

In view of the criminals using RFID to steal and swipe the bank card and bus card user information to commit crimes, RFID anti-theft wallet and RFID anti-theft card cover and other products began to appear in the market.


Recently, aiming at high-frequency (13.56MHz) smart card information anti-theft, the high-frequency anti-theft wallet was launched, which is specially used to protect the data security of chip bank card, second-generation ID card, city all in one card, bus card and other high-frequency smart cards. In appearance, the size of the wallet is the same as that of the ordinary wallet. When you put the bank card, ID card and other smart cards together in the RFID blocking signal wallet, your wireless signal of the smart card will be effectively shielded. No matter what device the lawbreakers use, they can't steal your card information, ensure safe carrying and prevent information leakage.


According to the social survey, at present, in people's life, the use rate of credit card, bank card, public transport card with chip is the highest. In the city, 90% of people basically have the experience of using IC card. The magnetic stripe card of the bank is being replaced by chip card. Many public transport cards with bank card collection and some micro payment and flash payment functions bring great convenience and speed to people's life at the same time, with the rapid development of technology, the mobile phone with NFC function can read the transaction information of bank card at close range, so that the personal financial information of the cardholder will be exposed, is it possible to be stolen? This is certain that the RFID blocking wallet plays the function of anti-theft, put it in the bag, and prevent malicious "magnetic touch". This shielding card can also be used in casinos On the chip, can play the role of anti-theft, anti tamper. Imagine the market potential.
