Abstract

A method of data transmission over existing telephone lines and later verification of that transmission includes electronic payment verification using telephone transmission of payment information and return transmission of a unique card account number, storage of the information and account number on a database and a data card through a data storage device, and verification of the infomation and account number at a later time by a separate data storage device and the same database.

Claims

1. A method of digital data communication and verification between a first computer connected to a storage means storing digital data and a first data card storage device interfacing with a data card capable of storing data, and a second computer connected to a second data card storage device, comprising the steps of:

the first computer transmitting the digital data to the second computer;

the second computer transferring the digital data to the second data card storage device;

the second data card storage device recording the digital data onto a data card, reading a unique data card account number from the data card, and transferring the unique data card account number to the second computer;

the second computer communicating the unique data card account number to the first computer;

the first computer storing the unique data card account number on the storage mean in association with the digital data;

the first data card storage device subsequently reading the digital data and the unique data card account number from the data card, and transferring the digital data and the unique data card account number to the first computer; and

the first computer comparing the digital data and the unique data card account number received from the first data card storage device to the digital data and the unique data card account number stored in the storage means.

2. The method of claim 1, wherein the first computer and the second computer communicate via a modem.

3. The method of claim 1, wherein the digital data includes identification of a payor of a sum certain and the sum certain.

4. The method of claim 3, wherein the digital data is encrypted.
