A LISMORE business owner is warning retailers to be vigilant in checking credit card purchases after his business was the victim of a fraud this week.
Powermax Computers co-owner Alex Clarke said the fraudulent transaction occurred on Tuesday when two men bought items from the store on two different stolen credit cards belonging to the same person.
He said the day after a Lismore woman's purse was stolen her credit cards were used in his shop.
"The two men came in independently, but around the same time, and with her credit cards purchased an iPad and a Mac Book Pro," he said.
Mr Clarke said the victim who owned the credit cards will be reimbursed for the fraudulent transactions by her bank, but his business was left to wear a significant loss.
"In both purchases they had to sign, and they forged the signature on the card," he said.
"This is the problem with credit cards, they aren't particularly secure."
To combat the problem happening again, Mr Clarke said the store has implemented a two step identity check for credit card purchases.
"If somebody comes in and wants to buy something using a credit card and they are a new customer, then we will be requiring that they produce a driver's licence or some other form of ID."
Richmond Local Area Command Crime Manager Detective Inspector Greg Moore said police had been alerted about the fraud and investigations into the incident are ongoing.
Det Insp Moore echoed Mr Clarke's calls for retailers to be vigilant.
