How wallet cards work

A wallet card links a card account to a wallet whose keys belong to you. When you pay, the issuer takes the needed amount from the wallet, converts it to local currency and settles with the merchant. Until that moment the coins never left your control.

The reviews in this section explain the surrounding machinery in each case: the fees, the supported coins and networks, the countries served and the structure of the issuer behind the card.

Self-custody shifts risk without erasing it. No one can bring back a vanished seed phrase, and the issuer standing between wallet and till may still freeze the card. Every review shows where those two points lie.
