RCMP in central Alberta are warning business owners – following a number of instances of credit card fraud at a number of local businesses.

Police said they have received a number of reports from businesses over the last month of some customers using stolen, cancelled or otherwise defective credit cards.

Investigators said the suspects try to use a large quantity of merchandise using a credit card.

It’s believed when the card is used; an error message appears on the pin pad, which the suspect reportedly manipulates to allow the purchase to be processed, before they leave the store with the merchandise.

Staff at the targeted stores are not aware of the fraud until the credit card company calls the store, and tells them what happened.

It’s believed the suspects use stolen, cancelled or otherwise defective credit cards.

RCMP are advising businesses to tell staff to not manually enter any credit card number, and to keep an eye on customers when they are using the pin pads.

Anyone with information on these crimes is asked to call Red Deer RCMP at 403-343-5575.
