STS compliant prepayment meters installed globally will need to be reset before 24 November 2024. That is the fixed date that all existing STS meters are programmed to stop accepting new prepaid credit tokens created after this date, unless the municipalities and utilities upgrade their vending systems to the STS Edition 2 specification. 

Each credit token has a unique token identifier (TID) encoded into the 20 digits to prevent token replay at the prepayment meter. The TID is referenced to a base date of 1993 and will run out of range in 2024 causing the prepayment meter to stop accepting new prepaid customer tokens.

All utilities are obliged to upgrade their vending systems to the STS Edition 2 specification. This transition involves resetting the memory of each prepayment meter before November 2024.
