Bank of America and VISA are testing from September VISA payments by phone.

A "digital wallet" with financial feature would be built into some sophisticated mobile phones. Visa and its technology vendors are providing select New York-area employees and customers with small chips that emit radio signals over very short distances.

They can wave these phones over specialized point-of-sale devices in select stores. These POS would collect bank account data to complete their purchases.

Also within the year VISA will conduct similar card payment tests with US Bancorp. Meantime Verizon Wireless, AT&T, T-Mobile USA and Discover Financial Services are also planning a joint venture to offer such mobile payments services.

This tentative new tech Sony calls “single wire interface technology” will replace those multiple cables. In their place is just one internal cable to transmit data and power in the phone.

The wire uses time division duplex and multiplex to communicate bi-directionally with other signal types like video, audio, and control signals. A unique encoding technology will transmit DC power and high-speed data within a limited frequency bandwidth.

The new interface can transmit at speed of 940Mbps and consume 10-80mW and 0.3mW when on stand-by. Using 1.5V/3.0V, it can transmit data and power for up to 60cm.
