Kem Card
Kemfinity s.r.o. · Visa
Kem Card is the crypto debit card from Kemfinity s.r.o., an entity registered as a VASP in the Czech Republic (Company No. 221 62 194). It is a virtual-only Visa card, spendable anywhere via Apple Pay and Google Pay: users deposit Bitcoin and other assets (USDT, ETH, tokenized gold XAUT) and spend stablecoins. The model is custodial with full KYC (verification via Veriff/Sumsub), multi-signature wallets and a physical gold vault backing the reserve. Issuance is free with no monthly/annual fee; a 1% transaction fee applies plus an FX markup of up to 3% on non-USD currencies. The rewards program advertises 2% cashback in Tether Gold (XAUT) on the official site, while third-party sources state "up to 3%": the figure is therefore ambiguous. ATM withdrawal is not documented (ATM limit set to 0): the card is effectively designed for payments, not cash. Global availability excluding sanctioned regions.

Very low sovereignty: custodial with full KYC, no self-custody or privacy; funds are held by a third party.
