Crypto wallet firm Tangem has announced a partnership with Visa to launch a new hardware wallet integrated with Visa payment cards. The product, expected to launch by year-end, will introduce Tangem Pay, a payment technology that allows users to spend crypto directly from their self-custodial wallet. The technology received certification from Visa in February 2022. Tangem Pay will be available to any self-custodial wallet, not just Tangem's, and the firm plans to develop a platform that will allow any wallet to issue cards under their own brand.
