description Tangem Wallet Overview
Tangem is a unique hardware wallet that looks like a credit card. It uses NFC technology to communicate with your smartphone, meaning there are no buttons or screens on the device itself. You tap the card against your phone to sign transactions. This design makes it incredibly portable and discreet.
While it lacks a screen for address verification (relying on the phone's display), it offers high-level security through its Secure Element chip.
help Tangem Wallet FAQ
What happens if I lose one Tangem card?
A wallet configured with two or three linked Tangem cards can still be accessed with a remaining backup card. If every card is lost, recovery is possible only if the wallet was created or imported with a recovery phrase that you retained.
Does Tangem require a battery, cable, or Bluetooth connection?
No, the card is powered through the NFC field produced by a compatible smartphone. Transactions are prepared in the Tangem app and authorized by tapping the card against the phone.
Can I use a seed phrase with Tangem Wallet?
Tangem Wallet 2.0 supports creating a 12-word or 24-word phrase and importing several standard phrase lengths. It also offers a seedless setup in which linked cards serve as backups, so the recovery model must be chosen during setup.
How is Tangem different from a Ledger or Trezor wallet?
Tangem has no screen or physical buttons and relies on a phone to display transaction details, while many Ledger and Trezor devices provide an onboard display. Tangem's card format is more portable, but users must be comfortable verifying information through the mobile app.
