Abstract

A method and apparatus for encoding transactions for goods and services using an e-receipt is provided. A consumer and a merchant conduct a commercial transaction using a distributed data processing system. An electronic receipt is recorded on a removable storage medium at a first data processing system. The electronic receipt contains data concerning the commercial transaction. The removable storage medium is then read at a second data processing system. After validating the electronic receipt, another commercial transaction or another stage of the original commercial transaction may be performed. The electronic receipt may be validated for a warranty claim on goods or services subject to the purchase transaction, and the removable storage medium may be an optical card or a smart card, either of which is able to store thousands of e-receipts and other electronic documents related to a commercial transaction, with the integrity of each guaranteed through digital signature, digital certificate, etc.

Claims

1. A method for maintaining inventory records of products being sold, the method comprising the computer-implemented steps of:

providing inventory records corresponding to a plurality of products for sale;

processing a purchase transaction for a first product of said plurality of products;

generating an electronic receipt comprising data concerning the purchase transaction;

using a first read/write device to write said electronic receipt to a removable storage medium;

using a second read/write device that is different from said first read/write device to read said electronic receipt from said removable storage medium;

validating said electronic receipt; and

in response to validating said electronic receipt,

providing an indication to proceed with a delivery of said first product and

updating an inventory record corresponding to said first product to reflect the delivery of said first product.

2. The method of claim 1 wherein said step of validating said electronic receipt further comprises inspecting a digital signature to verify the integrity of said electronic receipt.

3. A computer program product in a computer-readable medium for maintaining inventory records for a plurality of items for sale, the computer program product comprising:

first instructions for processing a purchase transaction;

second instructions for generating an electronic receipt comprising data concerning the purchase transaction;

third instructions for storing said electronic receipt on a removable storage medium;

fourth instructions for reading said electronic receipt on the removable storage medium;

fifth instructions for validating said electronic receipt; and

sixth instructions for providing an indication to proceed with a delivery of said first item in response to validating said electronic receipt,

seventh instructions for updating an inventory record corresponding to said first item in response to validating the electronic receipt.
