Isis, the US-based mobile commerce venture announced last November by AT&T Mobility, T-Mobile USA and Verizon Wireless, has acquired a number of new supporters.

HTC, LG, Motorola Mobility, RIM, Samsung Mobile and Sony Ericsson all say they’ll be introducing NFC-enabled mobile devices compatible with the Isis technology standards. In addition, Isis is working with DeviceFidelity to add NFC functionality to other mobile devices.

Orange and Barclaycard say the bada-powered Samsung Wave 578 will be the next mobile phone compatible with Quick Tap contactless payments in the UK.

The first phone, the Samsung Tocco Quick Tap, was revealed in May when the service launched.

The Google Wallet mobile payment application, which was announced by the company in May, is now being rolled out to customers in the USA.

It’s currently only available on the Google Nexus S 4G phone to customers who have a Citi MasterCard credit card or the Google Prepaid debit card and are using the Sprint network, although Visa, Discover and American Express are also expected to participate in the future.

Nokia has announced the latest version of the Symbian operating system - Symbian Belle - along with three smartphones that'll be launched with the new OS.

The Nokia 700, Nokia 701 and Nokia 600 will all include NFC technology that - thanks to Belle - will allow fast connections to compatible accessories. For example, the new Nokia Essence Bluetooth Stereo Headset can be paired with any NFC-enabled smartphone by tapping the two devices together.

Symbian Anna, the latest version of the Symbian mobile operating system, is now available for download.

Availability will vary from country to country, with the UK confirmed as one of the countries receiving updates today.
