how much data is used when i accept encripted chip credit cards payments on my iPhone

Look in setting, cellular usage, Aplle pay app.

 

 

To reiterate what @lizdance40 stated goto home page/settings/cellular data/select pay app that you use to see how much data. look before a payment then again after to see how much each use is.

this user from the looks of it is not talking about apple pay!....  He is talking about processing credit cards thru his phone with a paypal reader or square trade reader.  And it does not take much data to run those transactions I have a paypal reader I use for selling phones to people.

@GLIMMERMAN76   Thanks....re read seems to agree.   So any data can be tracked through the card reader app.

 

@lizdance40.

 

those apps report the data since they are really using it.
