Term Main definition
Vending Client

The Online Vending Machine that issues the Token to the Operator. The Vending Client does not have the capability to create a prepaid Token; it must request tokens from the Vending Server via XMLVend protocol. See Vending Server, Gateway, Client and Vending Terminal.

Vending Channel

Any method that a consumer may use to make payment and, as a result, receive a credit token that can be used to top-up a meter.

Vend Information Sources

Vend Information is the information that is required to Vend a Token. This information is typically stored on the Meter Database and also on the Meter Card but all these sources of information are not always available

Vend

A Vending operation or Vending transaction may be any one where a credit token is generated for a meter. This includes a normal sale, FBE token issue, Free token (if supported), and Credit Transfer token. This specifically excludes Engineering tokens and Key Change tokens. See Credit Token, FBE Token, Engineering Token, Meter Credit Transfer Token and Key Change Token

Utility Certificate

This certificate is generated on the Online Vending CA for every Utility that implements and XMLVend compliant Online Vending System. The server certificate identifies the specific Utility together with an EAN number. It ensures that all communication with the Vending Server is secured via TLS and this certificate. The Certificate does not directly identify the Vending Server hardware but the Utility. Since the Server Certificate is stored on separate hardware security module (HSM), the server certificate may be moved to another Server in case of a server failure for instance. See Vendor Certificate

Utility

Collective term for a service that is used by the public, such as an electricity, water or gas supplied by a local authority or utility distributor.

Update Meter Key

Update Meter Key is a new and simplified Key Change process. The Update Meter Key action is initiated by the Operator e.g. by selecting the appropriate button on the Client. The operator must then provide the “From” information from the Meter Card or sometimes via manual entry from an old token. This will create the normal Key Change tokens and encode the Meter Card. The only difference being that the meter information is always changed to become the same as the data in the Meter Database. This function therefore does not introduce any data risk and may be enabled for any operators. The operator may also retry this function multiple times with different “From” information until successful and the end result will always be the same as the data on the Meter Database. See Auto Key Change, Key Change Token, Engineering Key Change Token, Vendor Roles, Meter Database and Meter Card

Token Technology

A two-digit code defined by STS. There are codes for the various tokens used by STS as well as for the tokens used by proprietary meters. The combination of Token Technology and Algorithm Type, define the Meter Type

Token Carrier

A Token is only the data package that is created by the Vending system and subsequently inserted into the meter to transfer information to the meter. It does not necessarily define the physical media of the token. The physical media of the Token is defined by the Token Carrier. This is specifically relevant for STS since the Vending Server may create the same STS token for any STS meter and send it to the Client. The Client may then be locally configurable to support some, or all Token Carriers without having to communicate this with the Vending Server. Currently all tokens are stored on physical media, (i.e. numeric printed string, or disposable magnetic card). These are therefore defined as the Token Carrier. Virtual Tokens are under consideration as well but have not been implemented in meters yet. Virtual Tokens will not have a physical Token Carrier as they may be transferred via radio, power line communication or other means. See Mag Card and Token

Test Token

A test token is a credit token. A test token may or may not have a credit value and is used for the purpose of checking whether a meter will accept tokens from a vendor using a specified Supplier Group Code
