Cardian the Safecard Real Customers Reviews Alongside the basic operation, it’s important to be clear about what Cardian the Safecard does and does not block, because Cardian the Safecard’s protective scope is largely determined by frequency and proximity considerations that have real-world implications. However, Cardian the Safecard is not a universal blocker for every RFID frequency—older access cards and some building or hotel systems operate at lower frequencies such as 125 kHz, and Cardian the Safecard may not be effective against these low-frequency tags. That means that while Cardian the Safecard offers broad protection for financial and identity-related items, Cardian the Safecard should not be relied on to protect older, low-frequency access badges. These caveats help set realistic expectations: Cardian the Safecard provides focused, practical protection for the most common threats, while leaving edge cases like low-frequency systems to other solutions or to separate handling.
