This invention relates to methods for making a credit/debit card purchase without revealing the card number to the vendor of services or goods. The card holder is connected to a data base and provides the card number, plus holder identity verification, to the data base. The data base then verifies whether the card holder is authorized to incur the expense of the purchase, and, if so, provides an authorization indication or code to the vendor, the card number cannot be derived from the authorization information, thus helping to preserve the secrecy of the card number.
