6.3.3.2 Coin devices

The payment service reads the configuration of the payment device like the SupportedAssetList and the SlotConfigurationList. It may monitor the SupportedAssetListVersion to get notified, when the configuration has changed. It should monitor the Status of the payment device and take appropriate actions if it changes. The AssetConfigurationList defines how to handle specific coins or tokens and can be changed by the payment service using the ChangeAssetConfigurationList Method.

By configuring the AssetConfigurationList to reject all supported assets, the payment service can effectively disable a payment device.

By monitoring the CurrentAvailableValue the payment service knows how much money is currently in the payment device that a customer has already added to the payment device and can be used for a delivery. By calling the ConsumeAvailableValue Method, the payment service can actually consume part of the CurrentAvailableValue.

By monitoring the CurrentSlotContentList the payment service knows the available money currently in the payment device for payout. By monitoring the PayoutStatus the payment service knows about the status of any payout, that can be triggered by the PayoutByValue and PayoutBySupportedAssetList Methods.

A payout does not change the CurrentAvailableValue. If the payment service wants to trigger a logic, that a payout does decrease the CurrentAvailableValue, it needs to call the ConsumeAvailableValue Method in addition to the Method for the payout.
