No incidents or enforcement actions found in the last 36 months. Tangem Pay is run by Paera LLC, not Tangem AG. The card is legally a collateralised charge card. Your USDC or USDT sits in a smart contract you control, but Paera can liquidate it if a balance goes unpaid. The terms list a late fee of up to $40 and a liquidation penalty of up to $35. They also ask for 3 business days' notice before you withdraw collateral, while the app FAQ says you can withdraw at any time. The account is tied to a single Tangem Wallet, and losing that wallet means losing access to the card balance.
