Super-fast automatic sensors could soon replace “checkout chicks” at Australian supermarkets.

Shoppers may only have to push loaded trolleys through an automated checkout.

A sensor would instantly read the prices of the entire contents of the trolley and debit a customer’s account.

Technology for automated checkouts already exists, with various applications of radio frequency identification systems being developed world-wide.

In the system likely to adopted, tiny radio tags embedded into supermarket products would carry information including price, expiry date, colour and packaging.

The tag would not need to be scanned.

It would send out radio signals to a receiver, which could accept several hundred readings simultaneously.
