There are three common ways to block contactless scans: a blocking card like Guardality, an RFID-blocking wallet, or a sleeve for each card. Here is how they compare.
| Guardality card | RFID wallet | Card sleeves | |
|---|---|---|---|
| How it works | One card shields the cards next to it | Metal lining in the wallet | A metal-lined sleeve for each card |
| Keep your wallet? | Yes | No, you need a new wallet | Yes |
| Extra bulk | One thin card (1.1 mm) | None beyond the wallet | One sleeve per card |
| To pay by tap | Take the card out | Take the card out | Take the card out of its sleeve |
| Typical price | From $13.99 per card (10-pack) | About $13 to $55 | About $7 to $25 per set |
Wallet and sleeve prices are typical retail prices in October 2026.
