Can Contactless Cards Be Scanned in Your Pocket?

Contactless cards, also known as RFID (radio frequency identification) cards, have become increasingly popular in recent years due to their convenience and ease of use. They allow users to make payments or access services by simply tapping their card on a compatible reader. However, a common concern is whether these cards can be scanned and compromised while they are stored in a pocket or wallet.

How Contactless Cards Work

Contactless cards contain a small chip that emits a radio signal when it is brought into close proximity to a compatible reader. This signal contains information about the cardholder, including their account number and transaction history. The reader then processes this information to complete the transaction.

Proximity for Activation

Contactless card readers require direct proximity to the card in order to activate and read the chip. This means that the card must be physically close to the reader, typically within a few centimeters. If the card is not within this range, the reader will not be able to detect or scan the chip.

Multiple Cards in a Wallet

When multiple contactless cards are stored in a wallet or purse, they will not interfere with each other. This is because the cards only emit a signal when they are in close proximity to a reader. As long as the cards are not touching the reader, they will remain inactive.

Theft Risk

While contactless cards are designed to be secure, there is a potential risk of theft if the card is exposed or improperly secured. For example, if the card is protruding from a wallet or pocket, it could potentially be scanned by someone nearby without the cardholder’s knowledge.

Protecting Against Theft

To protect against unauthorized scanning, it is recommended to store contactless cards in a shielded wallet or cardholder that blocks RFID signals. This will prevent the cards from emitting a signal unless they are in close proximity to a legitimate reader. Additionally, it is important to keep contactless cards secure and avoid exposing them to unauthorized individuals.

Conclusion

In summary, contactless cards cannot be scanned in your pocket unless they are exposed or improperly secured. Contactless card readers require direct proximity for activation, and multiple cards in a wallet will not interfere with each other. However, it is important to take precautions to protect contactless cards from unauthorized scanning by storing them in a shielded wallet or cardholder and avoiding exposing them to unauthorized individuals.
