Today, I was out shopping with my wife. My fingerprint didn't get recognized multiple times and the transaction didn't go thru when it finally worked. So I used another card on samsung pay and it worked to save me from total embarrassment. Then at another store, my fingerprint did not get recognized for 5 consecutive times and it wiped out the whole samsung pay. I could not pay any longer for the day because I don't carry wallet any longer. I am 100% dependent on Galaxy S6. So for the rest of the day, my wife had to pay with her plastic card. She has iPhone 6S by the way she was not impressed with my Samsung pay..
When I got home I tried to add the cards again and the Citi double cash card was blocked for fraud prevention so I am on the phone now for 20 min to get that straightened out. Ugh..
This time I selected 4 digit PIN instead of fingerprint. Samsung fingerprint + my dry fingers in cool weather just don't work. *sad*
