Have had it set up for a long time with same CC and Bank. Touch ID works, card is active and Bank said I am activated and should work. I have done nothing new to iPhone other than update to 9.3.4. But, I used AP after I updated with no issue. The places it won't work are stores I have been using it with for a long time. I can remove card and re-add, then reactivate with my Bank. But, wondering if there is anything else I can try before I remove card. I searched and didn't see any 9.3.4 issues. Thanks --- Post Merged, Aug 14, 2016 --- I should add it turns on at terminal. But, when I use Touch ID it says try again. My CC is displayed during this time. --- Post Merged, Aug 14, 2016 --- In reading a couple threads at bottom of page, seems I need to remove and re-add card. Then restore. Doesn't seem redoing fingerprint will help as Touch ID is working. Last step is take back to ATT or Apple.
