Fraudulent skimming devices, like this one found by Hayward Police, look almost identical to the actual credit card machine it was placed over. These devices are placed on top of credit card readers and can be removed with little effort.
Please be on the look out for these machines and if you see one, report it to your local police. If you’ve been the target of a scam, please notify Alameda County District Attorney’s Consumer Protection Division at askcepd-da@acgov.org
