A modular point-of-sale system maintains current transaction screening data and complete transaction data at each point-of-sale processor (POSP) which provides service to a community of point-of-sale terminals (POST's). A wide variety of different customer transactions can be processed without reference to a remote authorization computer. By way of example, customer transactions may include: check authorizations, credit card sales, local store credit sales, debit account transactions, frequent shopper cards, coupons, etc. |
