About

SkimGuard

Features
Read full description

Skim Guard helps you check a card reader before you pay. It's free for shoppers. Card skimmers are small devices criminals hide on gas pumps, store registers and ATMs to copy your card. They can be hard to see. Skim Guard gives you a quick way to check before you swipe. How it works: Hold your phone near the card reader and tap to check. Get a clear answer: the reader looks fine, or it's better to use another one. See a map of where skimmers have been found near you, and where it's clear. Keep a history of every reader you've checked and what you found. A few simple habits also help: give the reader a quick look and tug, cover the keypad when you enter your PIN, and tap to pay when you can. If you use an EBT card, lock it in your EBT app between trips. Store owners can use Skim Guard Business to check their own readers every morning and keep a dated log. Learn more at skimguard.io.
