Token credit function:
Token Credit function deals with managing credit registers according to credit token transfer.
When credit transfer is accepted, the values of “Available Credit Register” and “Total Purchase
Register” are increased for the amount credit transferred.
Emergency credit function:
Emergency credit function is used in situations when “Available Credit Register Value” approaches
or goes under zero. For this purpose, three parameter objects are implemented:
1.
Emergency Credit Initial Limit
2.
Emergency Credit Limit
3.
Emergency Credit Threshold
“Emergency Credit Initial Limit”
is used once after meter installation for the purpose of enabling
the customer to make the first buy (or transferring the first credit from the management centre).
It defines the credit value which is available when emergency credit is first selected by the
customer.
“Emergency Credit Limit”
defines the credit value which is available after the value of “Available
Credit Register” reaches zero and the customer selects the emergency credit.
“Emergency Credit Threshold”
defines the positive value of “Available Credit Register” at which
the meter begins to notify the customer that the credit will expire. When the value of “Available
Credit Register” falls below the value of “Emergency Credit Threshold”, the meter starts
notification.
