Would rank this app higher, but it will not pair with the card reader. So they are able to charge us a higher per transaction cost. Read their response. Have worked with our rep. Still won't pair unless I reload the app EVERY DAY! Just reloaded the app AGAIN. 3-15-22 IT NEVER PAIRS WITH THE READER. The suggestion from swipe simple? Update EVERY app on my phone! I use very few of the apps that came with my phone and am not willing to fill my phone storage with worthless updated apps.
