Use a debit card attached to an account where you keep a limited amount of money and can refill it easily when you need more, instead of using a card attached to your primary account that has most or all of your funds.

If your bank allows it, put a limit on how much cash can be withdrawn in a single transaction or over a period of 24 hours.

If your bank offers app-based or SMS-based notifications for every transaction, turn the feature on.

Monitor your card statements for unauthorized transactions.

If your card has a chip, always use the chip-enabled card reader of POS terminals instead of swiping the card.

This won't help in cases where there's a rogue PIN pad, but it's good practice.

Cover the PIN pad with one of your hands while entering your PIN to prevent any rogue camera from recording it.

If there are visible seals on the machine for the service locks, check if they seem broken.

Look for signs of tampering such as unusual holes, pieces of plastic or metal that look out of place, components of a color that doesn't match the rest of the ATM, stickers that aren't aligned properly.

This video shows a cybersecurity professional discovering a skimmer attached to an ATM on a street in Vienna. Criminals typically use low-grade glue to attach skimmers because they need to return and recover them.

Wiggle or tug on the card reader and the PIN pad to see if they come off or move before inserting your card.

They also tend to install skimmers during weekends, when they're less likely to be seen, so try to avoid withdrawing cash from ATMs during weekends if possible. When deploying skimmers, criminals target ATMs that don't see a lot of foot traffic, are not inside banks or stores, and are not covered by many security cameras.

Avoid using ATMs that are installed outside buildings or are located in poorly lit areas.

A Visa report shows pictures of several types of physical skimmers found on ATMs around the world as well as modified standalone point-of-sale (POS) terminals sold on the underground market that can be used to steal card data.īecause of the large variety of skimming devices, there isn't any single way that consumers can avoid becoming a victim. Skimmers can also be installed completely inside ATMs, typically by corrupt technicians or by drilling or cutting holes into the ATM cover and covering them with stickers that appear to be part of the intended design. Some skimming devices are slim enough to insert into the card reading slot - this is known as “deep insert.” Devices called “shimmers” are inserted into the card reading slot and are designed to read data from the chips of chip-enabled cards, though this is effective only against incorrect implementations of the Europy, Mastercard and Visa (EMV) standard. However, as many countries around the world have moved to chip-enabled cards, criminals have adapted, too, and there are now more sophisticated skimmer variations. The purpose of this component is to steal the user's PIN, which, along with the data stolen from the magnetic strip can enable criminals to clone the card and perform unauthorized transactions in countries where swipe-based transactions are still widely used. This component allows criminals to get a copy of the information encoded on a card's magnetic strip without blocking the real transaction the user is trying to perform.Ī second component is usually a small camera attached to the ATM or a fake PIN pad that covers the real one. It is usually contained in a plastic or metal casing that mimics and fits over the real card reader of the targeted ATM or other device. There is always a card-reading component that consists of a small integrated circuit powered by batteries. Because of this, they come in different shapes and sizes and have several components. Physical skimmers are designed to fit specific models of ATMs, self-checkout machines or other payment terminals in a way that is hard to detect by users.

The data they capture is used to either clone physical payment cards or to perform fraudulent card-not-present transactions online. Whether hardware- or software-based, skimmers are tools that enable fraud.

More recently, the use of the term has been extended to include malicious software or code that achieves the same goal on e-commerce websites by targeting payment card data inputted during online purchases. In the security industry, a skimmer has traditionally referred to any hardware device designed to steal information stored on payment cards when consumers perform transactions at ATMs, gas pumps and other payment terminals.
