For purposes of this section, the TC20 transaction is created as
product of a TC69 transaction. This transaction code spreads the
payment amount to the different cardholder account financial fields,
based or the order of sequence defined in the PAYMENT SEQ
parameter for TC20. CardLinK provides 22 different ways of
processing payments that must be set at the TYPE level. At both the
TYPE and CARDHOLDER levels, TC20 causes several adjustments to
be made such as increasing the number of payments received, adding
the amount of the TC20 transaction to payments received, as well as
decreasing the cardholder’s cash or retail balance by the amount of
the TC20 transaction processed.
