Michael Batuev, VP of Global Products at Tangem on 2025 Paris Blockchain WEEK:
Key notes: TangemPay will be launched this year, relevant app will allow users to manage multiple wallets, swaps, buying crypto with fiat, converting crypto to fiat, and more. Visa involved transactions are authorized via a smart contract that ties to the cardholder’s data.
I can't remember if we already stated that Tangem Play has nothing to do with Tangem wallet.
Sure,
Play has nothing to do with Tangem wallet

Regarding Pay, Tangem CEO holds the opposite view.
The cards designed for POS payments
i.e. utilizing Tangem Pay technique will generally differ from regular Tangem wallet cards, though they’ll share some basic elements.
As for the mobile app, it seems they’re simply enhancing it to support Visa-eligible cards. I’d expect both types of Tangem cards to use similar key generation and backup methods, despite their different purposes.
