The Block reported that cryptocurrency payment app Oobit is launching a Visa corporate expense card exclusively for AI agents. 'Agent Cards' are virtual cards that allow direct payments at Visa merchants using USDT balances without converting them to fiat currency. One card is issued per agent, and expenditure control by category and limits per transaction/merchant can be set. Tether is Oobit's largest shareholder, having led a $25 million Series A round in 2024.
