RFID stands for Radio Frequency Identification. It is a technology that uses electromagnetic fields to automatically identify and track tags attached to objects. RFID tags contain electronically stored information, which can be wirelessly read and accessed by RFID readers or scanners.

 In the context of wallets, RFID technology is necessary to provide protection against unauthorized access to sensitive information stored on contactless cards, such as credit cards, debit cards, or ID cards that have RFID chips embedded in them. These RFID-enabled cards allow for convenient “tap and go” transactions, but they also carry the risk of unauthorized scanning or skimming.

The primary purpose of incorporating RFID-blocking technology in wallets is to prevent potential theft or unauthorized access to personal and financial data. Criminals can use portable RFID scanners to remotely read and capture the information stored on RFID-enabled cards without physical contact or detection. This process is known as RFID skimming.

By integrating RFID-blocking materials or linings into wallets, the electromagnetic signals emitted by RFID scanners are effectively blocked or attenuated, preventing unauthorized scanning of card information. This acts as a protective barrier, safeguarding sensitive data from potential identity theft, fraudulent transactions, or unauthorized cloning of cards.

In summary, RFID technology is necessary in wallets to provide an added layer of security and privacy by blocking unauthorized access to RFID-enabled cards. It helps individuals protect their personal and financial information, giving them peace of mind while using contactless cards in their daily transactions.
