The phone lets you do a lot of things paper (but mostly plastic) can't. Some we've released...

- Standardized electronic receipts with line item data available in real-time

- Instant and free peer-to-peer money transfers (you can use Bump)

- Set the tip on the phone when you're at a restaurant

- Storing multiple account numbers for frequent flier programs, insurance companies, school IDs, etc.

...and some we're still working on...

- Bill splitting

- Location based offers (coupons), automatically-applied when you pay

So there are a bunch of advantages to using the phone.

> This is the first I've heard of your product, but I agree it does solve all the problems I mentioned.

That is what every startup founder wants to hear. :)
