Paypal Change Machine
From Makers Local 256
Summary
I hate being at the office and not having dollars or change for the vending machine. I live in a plastic electric world and since america hasn't caught on to cell phone vending yet, here's an idea for a paypal authenticated change machine
Operational Concept
- User pays an email address a small amount of money, less than $5
- Server is notified of payment
- Server generates key code
- Server sends key code to change machine (medium could be SMS, internet, etc)
- Server presents key code on a web page to user
- Server emails key code to user
- User inputs key code into Change Machine
A Change Machine verifies that code is valid
- Change machine checks to see if it has enough change
AA It does, Change machine dispenses change AB It Doesn't, user can call for refund or use key another day B Change Machine verifies that code is invalid
- Change machine displays "code invalid try again" to user
