Card sales

[robinharman]

I have used SumUp for about six years and now have two of the variety with a built in SIM. I find these are better than the type using your phone. These work really well and will also tap into available Wi-Fi if desired. Despite my best attempts I have never managed to get them below 50% battery even at busy events.
You can get a running sales tally from the SumUp app on your phone which is useful.

I use Sumup and using my phone now to read cards is brilliant as I don't need to cart the card reader with me. Just have to remember the rear or the phone has the NFC so you can't plonk a card in the front screen and have to read phones back to back.

Yes, I've had a similar experience with the Zettle reader, which has never run flat even after 6 hours, and like all of them, has unlimited data. I do make sure to charge it the night before...
