It would be nice to make payments in stores simpler in the next release of the Android wallet. This would increases the acceptance of Pivx among stores owners and customers.
The store owner types in the correct amount of Dollar/Euro, the customer scans the QR code and makes the payment with Pivx. Just as easy as paying with a card. I use this already for Bitcoin and works fine. The only downside is that Bitcoin confirmations take too much time.
When this is done, I’m willing to approach stores to use Pivx as a means of payment. I hope to hear from you.
