VENDING SYSTEM (POS - Point of Sale)
A STS vending system is a system that is used to generate credit, keychange, and management tokens for STS based systems. Several forms of vending systems exist:
1. a standalone vending system connected to a security module and suitable printing facilities to print tokens
2. a token server that is hosted on the www and connected to a client, the client being the interface to the customer for the purchase of tokens. In this case, the token server is connected to a security module for the encryption of the STS token.
3. Other forms of vending systems may include such systems that accept an SMS, or use an application on a mobile phone to purchase STS based tokens. In such systems, the back-end of the system must always be connected to a security module for the encryption of the STS token.
