The vending machine is capable of carrying out both cash and credit card transactions and includes a certified credit card terminal for connecting to the credit card processing network. The present vending machine includes an integrated microprocessor to control the mechanical motion and position of the stacked carousels, accept payment from either cash or credit cards, maintain accounting records, provide printed receipts, and to control on-line modem communications with credit approval sources as well as dial-up auditing of machine's inventory.
