- It is necessary for the wallet to be completely covered with foil for security.
Wallet In Aluminum Foil: A video is being shared on social media, in which it has been told that the credit and debit cards and other government documents kept in your wallet can be accessed using radio frequency. After this, some people have started wrapping their wallets in aluminum foil. It may seem unusual, but aluminum foil can save you from this type of damage. In fact, this foil blocks certain radio frequencies, making it difficult to read RFID-enabled cards and documents. Although, this cannot be called a foolproof method, but it can be used as a trick.
Why was there need for foil?
Apart from cash, your wallet will contain credit cards, debit cards, office badges and many such government documents, which use Radio Frequency Identification (RFID) or Near Field Communication (NFC) technology. With the help of both these technologies, these cards can be read wirelessly. Like there is no need to swipe your credit card or debit card now. As soon as you approach the payment machine, payment is made without any contact. Scammers can also use this technology to access your cards in an unauthorized manner. To stop this, aluminum foil is being used.
How will aluminum foil protect?
Aluminum is a conductive metal, which can block or attenuate radio frequency signals. When the wallet is wrapped in this foil, it does not allow the RFID reader to communicate with the chip installed in the card etc. This means that no one will be able to read your card or other chip containing documents in an unauthorized manner. It is important to note that the wallet should be completely covered with foil. If there is a gap left in it then this method will not be completely effective.
Are the cards kept in your wallet not safe?
The answer to this question depends on the type of card. Most contactless credit and debit cards work on NFC technology. It works only over short distances and has many security measures to prevent wrong access. Therefore, the risk of theft is less through wireless means, but passwords and access badges etc. have a chip embedded in them, which can be read from a distance. You can use special accessories for these.
