Count-Up Mode - Buying Process
General
The buying process:
- The consumer presents their card.
- The card requests authorization for the count-up maximum charge amount.
- Once authorization has been obtained, the machine starts to operate.
- The consumer can stop the machine’s operation at any given time.
- With every Delta Time (DT) elapsed, the total charge is updated at the beginning of the delta time with an amount predetermined by the machine's operator (Credit per Delta Time).
- At the end of the operation, the consumer’s card is charged the total amount as per the mentioned formula - <Delta Time Count> * <Credit per Delta Time>.
- The Total Charge will be between the minimum and maximum charges.
Count-Up Examples

- 12 times 6 = 72 which is more than the maximum (70), so the machine stops working.
