A system (10) for carrying out transactions between a customer at a customer station (14) and a service provider at a service provider station (12), includes transferring a body (96, 140, 170) through a pneumatic transfer tube (26). The customer at the customer station provides inputs corresponding to a financial account through input devices on the body such as a card reader (72, 146, 172) and a keypad (74, 148, 172). Data input by the customer is stored in the memory (82, 158) on the body. After transfer to the service provider station, data in the memory is output to a charge device (56) which is operative to assess a charge to the customer's account responsive to data output from the memory.
