Vending System

Governed by the IEC 62055 international standard, this vending system completely eliminates the need for physical media, such as IC cards, by utilizing a virtual digital token for transactions.

The core mechanism of the STS system revolves around a unique 20-digit numerical code, known as a Token. When a user purchases electricity, the centralized vending management system utilizes advanced cryptographic keys to generate this token. The user then inputs the 20-digit code directly into the smart meter via a keypad, or receives it remotely via an AMI network. Upon receiving the token, the meter's internal system decrypts and verifies the code. Once authenticated, the corresponding energy credit is automatically added to the meter.
