WHAT IS TID?
• The Token Identifier (TID) that is contained in all STS compliant
tokens. It identifies the date and time that the token was
generated.
• It is used to determine if a token has already been used in a
prepayment meter.
• The TID represents the minutes elapsed since the 1st January
1993.
• The incrementing of the 24-bit field means that at some point in
time, the TID value will roll over to a zero value.
• Think of your car odometer rolling over to zero.
