The Block reported that cryptocurrency payment app Oobit will launch a Visa corporate expense card exclusively for AI agents. 'Agent Cards' are virtual cards that allow direct payment at Visa merchants without converting USDT balances into fiat currency. One card is issued per agent, and category-specific spending controls and per-transaction/per-merchant limits can be set. Oobit's largest shareholder is Tether, which led a $25 million Series A round in 2024.
