Not all cabs want to use it because 1. it's recorded and 2. "fees" that they don't want to pay. The strategy used in Chicago when a credit card machine isn't working is just to tell them you don't have cash and you're walking out if they won't accept a card ("for a 'broken machine'") Magically it starts working again. [The city of Chicago mandates that they must be able to accept credit cards]
