Abstract
Abstract A method of obtaining and providing card identifying information from a data card presented in connection with a financial transaction, the data card having a magnetic stripe and an embossed region containing identifying information, the method being carried out in a data card terminal. The data card terminal is operative for gathering credit card or check information required for customer transactions at a point of sale. The method comprises providing a transaction risk parameter selectively indicative of a first or second level of transaction security to be provided for the data card terminal. In response to the transaction risk parameter indicating the first level of security, verified card identifying information is provided if either the first data record region or the second data region contains valid card identifying information. In response to the transaction risk parameter indicating the second level of security, a second level security check is performed. During the second level security check the first data record region is compared with the second data record region to determine if the data contained in the two regions match. If the first and second data regions match, verified card identifying information is provided. The data regions may comprise magnetic stripe data or embossed characters on the data card.
