Introduction / Who is this for

This guide is for anyone who uses payment cards, especially for those who frequently visit gas stations and ATMs. In light of the increasing number of skimming cases, it is important to understand how thieves operate and what steps can be taken to protect your financial data.

How do card skimming thieves operate?

Skimming is the process by which thieves copy data from payment cards to later use it. There are several popular methods they employ to obtain this information:

• Gas station skimmers: Thieves install scanning devices in card readers at gas stations. They are often difficult to notice as they blend in with the original reader.
• ATM overlays: Many ATMs are vulnerable to skimming as thieves place overlays that copy data from cards during cash withdrawals.
• Hidden cameras: Thieves may also install hidden cameras near card readers to record users entering their PINs.
• Tap-to-pay: While contactless payments are convenient, they can also be susceptible to skimming. Thieves can use special devices to scan cards in users' pockets.

How to recognize a threat?

There are several signs that may indicate a card reader could be compromised:

• Improper fit: If the card reader appears loose, poorly fitted, or shows visible signs of tampering, do not use it.
• Unknown devices: Check for any additional devices near the reader that may be skimmers.
• Change in color or texture: Changes in the appearance of the reader, such as differences in color or texture, may be a sign that something is wrong.

How to protect yourself from skimming?

To minimize the risk of becoming a victim of skimming, it is advisable to take several steps:

• Use ATMs in well-lit locations: Choose ATMs located in banks or other well-lit areas.
• Inspect readers: Before using a card reader, examine it closely to ensure it does not look suspicious.
• Use mobile payments: If possible, use mobile payments, which are often more secure than traditional cards.
• Monitor your account: Regularly check your bank statements and immediately report any unauthorized transactions.
