Abstract
A secure system for creating digital receipts, while minimizing the amount of data that is encoded in the digital receipt. The digital receipt provides authentication for a transaction. A digital receipt may be printed in the form of a code. The digital receipt digitally encodes a transaction identification code, a transaction amount or number of units authorized, and a digital signature. The digital receipt may be scanned or read to verify the authenticity of the transaction.
