Abstract
A vending system is disclosed which is adapted to be installed in a hotel or the like for permitting the guests to buy articles in a refrigerator or vending machine in a guest room without use of coins. When a guest inserts his memory holder into a vending machine and selects an article, an article code or codes representative of the article or articles he bought are transferred from a transmitter in the vending machine into the memory holder, and an accounting machine reads out the data in the memory holder to prepare a bill. Optical, magnetic or high frequency data transmission is used between the vending machine and the memory holder and between the memory holder and the accounting machine so that no data transmission line is required.
