QR or Bar codes - Ocado and Tesco follow different routes

This has absolutely nothing directly to do with 50-plus marketing.

A while back I became interested in QR codes and recently blogged about the way they are being used by the UK's largest supermarket (Tesco) in Korea.

Well now Ocado, the UK's largest home delivery only supermarket service, has started a similar "shopping wall" experiment in London. What is interesting, at least to me, is that instead of using QR codes they are using good old fashioned bar codes.

In the press release about the Ocado experiment it said that 15% of its transactions are now being made by mobile phones. This mobile thing is really happening. Dick Stroud Added in December 2011 - the same idea has moved to Singapore.
