/ pebble time

I just paid for coffee using my Pebble

So my University started using Yoyo for payments via phone, nice idea but I'm sure this is an issue. So after your entering your security pin (hmm a login) you get your barcode which you display for them to scan to proceed with the payment.

So I thought, what if I take a simple screenshot of said barcode, put it on my Pebble and get them to scan my Pebble...

It worked

Something this simple really worked and no questions were asked... This is awesome but now I'm really worried about someone getting hold of my barcode. All someone needs is your barcode and they can pay for things. All it took me to do this was take a screenshot, run the barcode app for Pebble and I was on the express route of taking there "fast" payment to a even faster method.
