What is Card Skimming?
Card skimming is data theft from credit or debit cards. It involves copying card details using hidden devices.
These hidden devices are called card skimmers. Criminals install these devices on payment terminals to steal data from a card’s magnetic stripe. These devices are often designed to look like a normal part of the machine, making them difficult to spot.
Here’s how they operate:
- Overlay Readers: These are the most common type of skimmer. A fake card reader is placed directly over the real one. When you swipe your card, it reads your data before passing it to the legitimate machine.
- Internal Skimmers: Some criminals are sophisticated enough to install skimmers inside a gas pump or ATM, making them completely invisible from the outside.
- Fake Keypads / Pinhole Cameras: To capture your PIN, criminals often place a fake keypad over the real one to record your keystrokes. Alternatively, they might install a tiny camera hidden nearby, aimed directly at the keypad.
- Bluetooth Beacons: Modern skimmers can use Bluetooth technology to transmit the stolen data wirelessly to a nearby criminal, who can collect it without ever returning to the machine.
The most places where these devices are put on are ATMs, gas pumps, and point-of-sale (POS) terminals at self–checkout lanes—places where there is less direct employee supervision.
Start Card Skimming
It can benefit to do card skimming by yourself. Using card readers allows you to steal information from multiple cards simultaneously, rather than just one individual’s card. This method will collect big batches of card data in one go (Dumps and Pins).
