There could be many reasons why consumers are not using the NFC chip in their devices to pay at the register. Privacy issues aside, the option just doesn't have an app that everyone is buzzing about. However, Isis wants to be that app for you, and in an attempt to make that happen, they have struck a deal with Wells Fargo banks. The deal made by Isis and Wells Fargo will benefit the customers of the bank who have NFC enabled devices. This offer is a limited time only offer and only for those of us that have a Wells Fargo logo on our credit or debit cards. The details of the offer are essentially a cash back sort of plan.
During the run of the offer, users who use Isis and Wells Fargo to pay at registers, will get $20 in account credit, just for signing up. After that, joint customers can get 20% cash back on every Isis purchase made, in the form of "statement credits," though this plan has it's limit. Each customer using the offer, can only get up to $300, and only $100 per month. The offer is only valid until April 2014, so with the $100 monthly limit, you will have to use this offer for each month it is available. This is their way of making sure you don't get $300 in one month and then uninstall.
The issue here may not be the app or even the privacy issues, instead it could be retailers. It is not every store you walk into that has a way to use NFC payments at the register. Which means consumers would have to make sure that the stores they visit have compatible hardware. The main idea behind the software, is to leave the wallet or cards at home, and only use your device. That just isn't possible when not every store or restaurant has the hardware to make it happen. When was the last time you used NFC to make a payment at the register? If you have used this feature, what apps have you used to pay via NFC chip?
