Payment network company Payzone has stated it has "no problem" with retailers offering rival terminals alongside its own in stores.
And company bosses say they want to make it clear that any contracts which still contain an exclusivity clause will be amended to allow multiple terminals to be installed.
The company is urging fellow providers to follow its lead. Deputy managing director Paul Charmatz told Convenience Store that Payzone is adopting a more modern approach to its contracts by offering them on a 28-day basis. "We feel retailers should have the choice as to how many terminals they install," he said. "If they want more than one we are more than happy with it.
"Just because you sell The Sun it doesn't mean you can't sell the Mirror. We welcome healthy competition and hope other providers will follow our approach. We want to go on record to say that any of our old contracts which say another terminal is not permitted are no longer valid."
Convenience Store has been contacted by a number of retailers unsure of the best way forward after being served notice by providers insistent on an exclusive contract.
One retailer who has more than one terminal in his store, and who preferred to remain anonymous, said: "I've been told I have to offer just one terminal by one of the companies I use and have a month to decide. I think it should be my choice if I want to have more than one."
