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.
