Have You Ever Used RFID To Block A Wallet?

RFID cards are widely used in our daily lives. RFID cards are chip cards with frequency sensing, which contain IC or ID chips. Our bank cards, ID cards, access control cards, credit cards, transportation cards, etc. are all of this type. People who carry wallets with them will keep these cards in their bags. With the development of cities and the advancement of technology, many cities have launched the use of bank card UnionPay flash payment services to take subways and buses, greatly facilitating people's travel.

 

At the same time, people are increasingly using NFC functions on their phones to pass through the subway and take public transportation. A mobile phone with NFC function can read bank card transaction information up close, exposing the cardholder's personal financial information and potentially causing theft.

 

Moreover, the large number of people on buses and subways can easily cause overcrowding, providing a great possibility for personal theft of bank card information.There are also RFID anti-theft card covers available for sale in the market, but when we go out, we don't only carry one or two RFID cards at a time. When carrying multiple cards, we need to use multiple card covers accordingly, which not only increases the thickness of the wallet, but also makes it difficult to use. When using, we need to take the card out of the cover and put it back. At this point, a new product - RFID shielded wallet appeared.

 

RFID is a general term for wireless radio frequency technology systems, which can identify specific targets and read and write relevant data through wireless signals without establishing mechanical or optical contact between the identification system and specific targets. The radio signal is transmitted from the tag attached to the item through an electromagnetic field tuned to a radio frequency, in order to automatically identify and track the item. For example, the RFID chip in a credit card contains the information required to authorize transactions, and the RFID chip in an access control card has a code to open the door or restrict the system. However, conductive metals can reflect, absorb, and cancel electromagnetic waves, so the card case (or sometimes the entire wallet) of RFID shielded wallets draws on this principle.

 

Is the RFID protected wallet worth purchasing and using? Undoubtedly, the concept behind RFID shielding cards is reliable. The card contains a lot of our information, and if this information is stolen and our personal information is leaked, it will cause unimaginable consequences.

 

So, an RFID blocked wallet is worth purchasing and using, even in the current environment, the probability of information theft is very low. Meanwhile, RFID shielded wallets can also be exquisitely crafted and can be used as normal wallets, so why not use them?
