The best electronic receipts I have seen so far appears to be emailing receipts to customers. I would like to know: how do people think electronic receipts should work? What could they be be used for?<p>More specific questions:<p><pre><code> - How should the data be transmitted (NFC, Email, etc)?
- Who should store the data?
- What could the data be used for?
- What organization could own the data standard?
- What are current examples of progress being made for electronic receipts?

Thank you for your input.
