  • Best Answer:

    Square requires a live Internet connection in order to authorize payments. Thus, if you are connected via Wifi, your data plan will not be affected, but if you use the phone's data connection, standard data usage will apply. With that said, the amount of data that Square transmits is probably on the scale of sending an email, and shouldn't use much of your data allotment.

  • It uses either Wi-Fi or the device's data plan. It uses very very little data, however.
