What is skimmer?

Skimming refers to the fraudulent practice of obtaining credit card data by attaching a device known as a skimmer to a payment terminal. Criminals use skimmers to steal magnetic strip data when a card is swiped, which can then be used to create counterfeit cards or make unauthorized transactions.

Here's how skimming works:

1. Skimmer Installation: Criminals install a skimmer device over the existing card slot of a payment terminal, such as a card reader at an ATM, gas pump, or retail store.

2. Data Collection: When a customer swipes their card through the payment terminal, the skimmer reads and copies the magnetic stripe data, which includes the card number, expiration date, and other cardholder information.

3. Retrieval: After a period, the criminals retrieve the skimmer, collect the stolen card data, and transfer it to a blank card or store it electronically for later use.

Skimmers are often small, discreet devices that can be challenging to detect, making it essential for consumers to be vigilant when making card payments. Here are some tips to protect against skimming:

- Inspect the card reader for any suspicious attachments or alterations.

- Check for signs of tampering or glue residue around the card slot.

- Be cautious of unusual card readers, especially if they are loose or not properly secured.

- Use chip-enabled cards instead of magnetic stripe cards whenever possible.

- Monitor your bank account statements regularly for unauthorized transactions.

- Notify the authorities or the merchant immediately if you suspect a skimming device.

In addition, always use strong and unique PINs for your cards, and consider using contactless payment options like mobile wallets or tap-to-pay cards whenever available. By following these precautions, you can reduce the risk of becoming a victim of skimming.
