OK, so I went to Save Mart yesterday and was checking out. I've used Apple Pay many times with no issues. However, yesterday something happened that has not happened to me before and I did't know how to fix it. So I was checking out and I held my phone up to the reader and while it was verifying my finger print I accidentally pressed the home button down. This caused the verification process to be disrupted and my home screen appeared. I tried to hold the phone back up to the reader but nothing happened. SO I ended up getting out my card and scanning my card. What (if anything) could I have done to re-initiate the communication between the reader and the phone so the I could have finished the transaction with Apple Pay?
