PAYMENT METER
A payment meter (also known as a pre-payment meter) is a device that accepts credit and management tokens from an STS Vending or management system and acts accordingly depending on the token.
1. Credit token – the payment meter updates its credit register with the amount contained in the token and dispenses a utility until the credit is depleted
2. Keychange tokens – the payment meter will change its key and possibly other parameters according to the contents of the keychange tokens
3. Management tokens – these tokens allow certain meter parameters (such as maximum power limit, tamper reset etc)
The STS supports the following meter types:
1. Electricity (kwh)
2. Electricity currency
3. Water (cubic meters)
4. Water currency
5. Gas (cubic meters)
6. Gas currency
7. Time (minutes)
