PAGOPACE
Leading provider of NFC payment rings.
We were already able to offer our customers good hardware with our payment ring. However, Johnny Bytes helped us to build the perfect complementary software to take our product to the next level. We were kept up to date at every stage of the app development and were able to make requests immediately. With the new app, we can also sell our rings in retail stores, as customers can link their rings directly to their payment card on their cell phone.
