Background and strategic fit

Merchants offer Gift Cards. Like any card, Gift cards have a ledger balance and transactions in the ledger. Unlike credit cards, Gift cards support partial balance transactions, where a gift card can be used to pay down part of the balance, and a second form of payment can be used for the balance of the transaction.

Assumptions

Transaction speeds support e-commerce transactions and point of sale transactions.
