According to this brief blurb in the Sydney Morning Herald, Sony is planning to sell some small electronic devices (including PSPs, digital cameras, Walkman players, games and DVDs) through what basically amount to advanced vending machines. Apparently the devices have already been rolled out at shopping centres in Georgia, Colorado and California, with other trials expected in the coming months. Also from the article:
Products are selected via a touch screen and payed for by credit card and a robotic arm with built in sensors then dispenses the goods, ensuring the shopper has received it before their card is debited.
The units were built by US company Zoom Systems using robotic technology from Japan and were designed to reflect Sony's corporate logo and image.
