Count-In Mode (Including configurations)

General

As an extension of the count-up mode, the count-in mode defines the amount to pay according to pulses provided by the machine (input line), rather than according to the amount of time that has elapsed.

Full scenario:

  • The consumer presents their card:
    1. The device obtains authorization for the count-up maximum charge.
    2. A signal is sent to the vending machine in Pulse 1 to start working.
    3. The machine pull-down the inhibit wire.
  • The consumer selects a product in the machine (there is a configuration for no product selection)
    1. The machine sends pulses to the device in Pulse 2.
  • Stop session
    1. This can happen if:
      1. The consumer presses the Stop button on the machine - pull-up Inhibit.
      2. The consumer presses the Stop button on the device – send pulse on Pulse 1.
  • The amount payable reaches the maximum charge value - send pulse on Pulse 1.
  1. The device performs the settlement.
  2. The device updates the machine upon settlement - send pulse on Pulse 1.
  3. The machine pull-up Inhibit, else the device send alert to server.
  • The device displays the Thanks You and Amount Charged screens.
