The Macclesfield-based company specialises in printing plastic keyfobs, increasingly used by retailers offering reward schemes to customers.

Recently the company produced its six millionth key fob and sales director Adam Unsworth said that had topped off a six month period that has brought in £1m worth of new business to the £5m turnover company.

He said: "Key fobs can give companies a range of additional benefits that you don’t necessarily get from traditional cards so we are finding that many of our clients, particularly retailers, are choosing this in addition to the standard card offering."

 "Basically, consumers and businesses alike love cards - it’s something that we are all familiar with, have confidence in and feel we can rely on. The key fob is an extension to this, adding value and giving retailers an alternative interface with their customers."

PCS invested £200,000 in a punch in September in order to handle the increase in business, which included the launch of retailer Holland & Barrett's reward scheme.
