(Salem, OR) -- Oregonians with EBT cards should take precautions to avoid having their card number and PIN stolen. The Oregon Attorney General's Office says there's been a 50 percent increase in money stolen from EBT accounts. They believe there's a traveling group that's placing skimmers over card devices in stores. They're often found in discount stores and small markets. EBT card holders should use the app to turn the card on only when making a purchase and then turn it off. Check card devices for an overlay skimmer. And if the card device has a yellow security sticker make sure it doesn't appear compromised.
