The world of NFC for payments using a mobile phone is growing rapidly with Google Wallet going official and already in use in some stores. Another competing offering that is in the NFC fight against Google is Isis. Isis is a NFC joint venture between some of the largest companies in the mobile sector including AT&T Mobility, T-Mobile USA, and Verizon Wireless. Isis previously vowed to rival Google Wallet and to support Android devices as well.
Isis has now announced that just about all of the major smartphone vendors on the market are putting the weight behind Isis technology. HTC, LG, Motorola Mobility, RIM, Samsung Mobile and Sony Ericsson have all announced that they will be introducing devices that have Isis NFC technology standards inside. Isis is also going to work with DeviceFidelity to add NFC tech to devices that lack it internally.
Isis NFC will allow consumers to make payments, store loyalty cards for retailers they frequent and use those loyalty cards inside the store without having to keep up with a physical card. I think the key to what tech is able to make it in the market between Google Wallet and Isis will be retailer support and the support of device makers.
