CryptoWorld news reports that Oobit has announced the launch of Visa-supported corporate expense cards for AI agents—Agent Cards. This virtual card enables AI bots to make purchases directly using their USDT balances, without converting to fiat currency and without requiring manual involvement at every approval step. Agent Cards include enterprise control features such as spending limits, category restrictions, and per-transaction/per-merchant amount limits. Every transaction is automatically recorded and generates an expense report with a “readable reason.”
