Pundi X is a great project. I just hope it can get mass adopted. However, i think the best payment platform right now is "Dunkin Donuts App".

Super easy to use.

1. download the app
2. create free account
3. load prepaid amount
4. start paying with the app. the cashier scans the barcode on the phone to pay. no reason to reach for the wallet. Also i get my coupons and rewards on the app as well.

All business should be doing this.
