Dunnhumby, the loyalty company that runs Tesco's Clubcard, is to launch a new service to help suppliers predict the future.

Dunnhumby Future Trends will use the company's huge wealth of data to enable Tesco and suppliers to spot trends and analyse purchasing habits. Dunnhumby will launch the service in the UK first before rolling it out internationally.

"We are sitting on so much data about what people do," said an insider. "We want to start to use the data to be much more predictive about what is going to happen next and to analyse the data in a slightly different way to spot emerging opportunities."

LMG, the company behind the Nectar loyalty card used by Sainsbury's, last year launched a subscription website offering suppliers access to Sainsbury's till roll data. It is designed for suppliers to analyse market trends and shopper behaviour.
