In life, people who carry wallets will have bank cards, credit cards, and transportation cards in their bags. Recently, many cities have launched the service of using bank cards UnionPay QuickPass to take subways and buses, which greatly facilitates people’s travel.

At the same time, more and more people use their mobile phones to use the NFC function to pass through subway gates and take buses. The mobile phone with NFC function can read the bank card transaction information at close range, so that the personal financial information of the cardholder is exposed, resulting in the possibility of being stolen.

Moreover, there are a lot of people in the bus and subway, which is easy to cause crowding, which provides a great possibility for personal theft of personal bank card information.

So how to prevent bank cards and other cards from being stolen? There are RFID anti-theft card holders and other products on the market, but the RFID anti-theft card holder can only be used for one set of cards. If there are multiple cards, multiple card holders should be used accordingly. Take the card out of the sleeve and put it back. Therefore, there is another very simple method, that is, the RFID shielding wallet.

What is RFID Blocking?

Radio Frequency Identification (RFID) is a wireless communication technology that can identify specific targets and read and write related data through radio signals without the need for mechanical or optical contact between the identification system and specific targets. Radio signals transmit data from a tag attached to an item through an electromagnetic field tuned to a radio frequency to automatically identify and track the item.

For example, an RFID chip in a credit card contains the information needed to authorize a transaction, and an RFID chip in an access card has a code to open a door or a restricted system. However, conductive metal can reflect, absorb, and cancel electromagnetic waves, so the card holder (or sometimes the entire wallet) of the RFID shielding wallet borrows this principle.

How does the RFID Blocking Wallet Work?

RFID chips work by using radio waves to communicate. Taking a credit card as an example, an RFID tag with information is embedded inside the credit card, and banks or consumer places only need to use an RFID reader to read the information on the tag through radio waves.

The key is that the RFID chip has tiny electromagnetic waves, which allow it to be read without “activating” the communication, so the RFID reader only needs to be close enough to read the cardholder’s identity information.

Fortunately, radio waves are also easy to block, which is how RFID blocking wallets work. Simply enclosing the credit card in a material that interferes with radio waves blocks all electromagnetic waves, preventing communication between the card and the RFID reader.

With such advantages, is the RFID blocking wallet worth buying and using?

Summary and Outlook

There is no doubt that the concept behind RFID blocking cards is solid. As a credit card holder, the card contains a lot of our information. If this information is stolen, the consequences will be unimaginable. If it is a “high value” target group, such as IC card bank staff with access to valuable or sensitive assets, then using RFID blocking card holders or wallets is a must.

Therefore, an RFID shielding wallet is worth buying and using, even if the probability of fraudulent information is very low in the current environment. At the same time, RFID blocking wallets can also be beautifully crafted and used normally, so why not use them?
