SaiTech IT RFID Blocking Card 5-pack 🛡️

This slim protection card blocks RFID and NFC signals to help keep contactless bank cards and ID data safer when carried in a wallet or purse. It works passively, offering a compact barrier that can be slipped into card slots for everyday use and travel, with clear on-terminal testing procedures to confirm operation.

Key Points

The blocker uses an embedded antenna and blocking chip that interrupts radio waves, so it does not require a power source. It is built to fit the size of a credit card while remaining extremely thin, which keeps wallets and cardholders from becoming bulky. Consider that it may not affect low-frequency cards operating at 100 KHz to 125 KHz according to the manufacturer. 🛡️

Benefits

This pack of five gives you spare units to place throughout different compartments or to share with family members. The passive design means long-term reliability because there is no battery to drain or replace. For everyday shoppers and commuters who use contactless payments, the card offers a simple way to add an extra layer of privacy without changing how you carry your cards. The design also allows quick function checks at a self-checkout terminal so you can verify protection in seconds. 💳

Usage Recommendations

Place one blocker in the same slot as contactless credit or debit cards, or between two cards to protect both sides. When testing at a payment terminal, put the blocker adjacent to a contactless card and observe that the transaction fails to register, which demonstrates proper function. For travel, spread the five cards across different bags and wallets to keep multiple sets of cards guarded. Also remember that physical wear could affect performance over many years, so consider periodic verification if you carry the blocker daily.
