-This EIP proposes a standard schema for digital receipts of transactions. Digital Receipt Non-Fungible Tokens are issued by a vendor when a customer makes a purchase from their store and contains transaction details necessary for record keeping. Digital Receipt Non-Fungible Tokens extend [EIP-721](./eip-721.md) which allows for the management and ownership of unique tokens.

 ## Rationale
 
-The schema introduced complies with EIP-721's metadata extension, conveniently allowing previous tools for viewing NFTs to show our receipts. The new property "receipt" contains our newly provided receipt structure and the signature property optionally allows the vendor to digitally sign the receipt structure.
