They’re also advised to consider their personal safety when dealing with anyone trying to pass counterfeit currency.
A police spokesperson said: “Retailers can take simple steps to avoid being scammed in this fashion by using counterfeit note detector pens or UV scanners,.
“Both greatly increase the chances of picking up a counterfeit note before change has been passed of goods supplied.
“Anyone who deliberately uses counterfeit currency is committing a crime and we will investigate all instances reported to us”.
