The city of Fresno also put out warnings online, encouraging consumers to check card readers and ATMs before inserting their cards.
It's been happening for years -- Crooks place skimming devices on gas pumps or card readers and steal your credit card information.
Surveillance footage shared with Action News by the Food Shop on Elm and Jensen shows how quickly a skimmer can be placed on a point of sale device.
It takes the crook less than five seconds to pull out the skimming device and place it right on top of the card reader.
The device looks just like a regular card reader.
This incident happened last year and the then-manager of the shop tells us he called police, but the crook got away.
Fresno Police has some tips for you to protect your bank account:
- Gently pull on the point of sale device to see if an overlay is installed
- If possible, only use ATMs inside of banks, during business hours
- Monitor your bank and credit accounts daily to verify charges
- Set up text or email alerts to notify you when purchases are made
If you notice fraudulent activity, make sure you call the customer service phone number on the back of your card. A number you find on the internet could be a scam.
If fraud does occur, Fresno Police says you should always file a report.
