1. These validate the coins and bills and communicate with the vending machine
controller through a serial communicaon interface.
2. Once sucient credit has been accumulated a vend will be permied. Where possible
the change giver will return the appropriate amount of change to the consumer.
Note: The COTI machine is MDB or Execuve Protocol compable and the LINEA machine is
MDB compable only.
7.14 Card/Key System
1. The card system ed to the machine communicates with the vending machine
controller using the same principle as the change giver.
2. The card system informs the vending machine controller of the amount of credit on
the consumer's card. If there is sucient credit for the selected drink the vending
machine controller permits a vend and informs the card system of the amount of
credit to be taken from the card. The new balance will then be re-wrien onto the
consumer's card.
