Corporate card
A card an employer issues to staff for travel and expenses, so nobody has to front costs from their own pocket and wait to be reimbursed.
The card carries the employee's name but the debt belongs to the company, at least under the common central-billing model. The alternative, individual liability, has the employee pay the statement and claim the money back, which mostly just postpones the expense-report problem by a month. For decades the market was effectively American Express, whose green card became standard business-traveller kit in the 1960s.
What changed is what happens after the purchase. Startups like Brex and Ramp built their business on the card and the expense system being the same product: snap the receipt in the app, let the books code it automatically, and set category limits before anyone gets round to buying a golf trip. The issuer earns its keep on interchange, which runs noticeably higher on corporate cards than on consumer ones.
