The telecoms giant can now place self-adhesive graphics over existing ones when in-store displays are ready to be changed. PoS supplier Charterhouse said that layering T-Mobile's PoS rather than replacing it would equate to a total cost saving of £600,000.

The print management company added that the system provided a 30% reduction in time to market and a 45% reduction in packaging.

T-Mobile head of retail campaigns Sarah Smith said: "This project has had results above and beyond our expectations.

"We are making significant savings on materials, collation and distribution costs. We are working towards having a full closed-loop production cycle, which means that all waste is tracked and then reconciled in one central location," she added.

"We want to be a socially responsible retailer and recycle and re-use 100% of all our PoS material. Charterhouse has helped us achieve this."

Charterhouse argued that T-Mobile's previous system was time-consuming and that the PoS was bulky to produce and collate and costly to transport.

It also said it had to be collected from a central store, which resulted in around 3,000 trips.

Charterhouse recently won a multi-million pound print contract for food and healthcare giant Unilever following a competitive tender.
