NFC Payments ISIS or Google Wallet
I have Google Wallet all setup on my N5 with my American Express card. It works fine for all GW transactions except Tap and Pay (NFC). I get a message that the transaction has been declined by card issuer. When I swipe the card at the same terminal it goes through no problem.
I contacted American Express to find out why the charges are declined. Amex initially said they see no declined transactions on their end. After further investigation with Amex tech support I was told the Amex does not support GW Tap and Pay so the NFC transactions never even gets to them. He suggested I try ISIS Mobile Wallet which they fully support.
When I try to install ISIS from the Play store there are 3 options. ATT, Verizon and T-Mobile. I am on Straight Talk using an AT&T SIM so I tried that one. When try to install it's grayed out with "No eligible devices for app install". I also tried the other two options with the same result.
So I started looking for the ISIS apk to manually load the app and found post about needing a special SIM and carrier restrictions. Also saw that it does not work on rooted phones.
My questions are:
1. Has anyone been able to an Amex card to work with Google Wallet Tap and Pay (NFC)?
2. Is there any way to get ISIS loaded and working onto a stock rooted Nexus 5 using a Straight Talk plan?
