Abstract
Abstract A credit verification system comprising a multiplicity of pointof-sale terminals and a programmed central processing unit with data storage equipment communicating with the terminals for automatically performing a credit check on the accounts corresponding to the credit cards inserted in the terminals. Each of the terminals is adapted to receive and operate with a plurality of different credit cards representing different credit card plans with the data storage equipment storing account information for each of the credit plans. After the various credit checks are performed by the central processing unit, the transaction authorization is communicated to the terminals. In certain instances, the central processing unit may refer the transaction to a video display terminal where an operator establishes voice communication with an external authorization center.
