What is a Shimming Device? Avoid Card Skimming Scams.


Updated on:

there’s one question I’m always asked: How can I avoid becoming a victim of card skimming scams? It’s a valid concern because these scams have been around for a while, and they don’t seem to be going anywhere. However, there’s another way that criminals are targeting your cards, and it’s called shimming. You might not have heard of it, but it’s just as dangerous as skimming, if not more so. In this article, I’ll explain what a shimming device is, how it works, and most importantly, how you can protect yourself from falling victim to this insidious crime. So, grab a coffee, settle in, and let’s dive into the world of shimming – the next big threat to your financial security.

What is a shimming device?

A shimming device is a tiny, thin gadget that can be inserted into card terminals to obtain EMV chip information. It functions similar to skimmers, which used to depend on magstripe data to carry out fraudulent activities. EMV microchips have largely replaced magstripes and are more secure against skimming. However, fraudsters have devised a new strategy to steal financial information using shimming devices. Here are some key points to understand about shimming devices:

  • Shimmers can read information from EMV chips, whereas skimmers can only obtain data from magstripes.
  • A shimming device is the size of a SIM card and can easily fit into the card slot of a payment terminal.
  • Shimmers are difficult to detect as they can hide behind the chip reader in a payment terminal.
  • The information obtained by a shimming device can be used to create counterfeit cards or for fraudulent online purchases.
  • To protect yourself from shimming devices, pay close attention to your credit and debit card statements. Report any suspicious activity to your bank immediately.
  • It’s also worth noting that shimming devices are not foolproof, and sophisticated fraudsters may use other techniques to obtain your financial information. Therefore, it’s always important to remain vigilant and take necessary precautions to protect your financial information.

    In summary, while EMV chips have significantly reduced the risk of skimming fraud, shimming devices have emerged as a new threat to financial security. Being aware of these devices and taking necessary precautions can help safeguard against potential financial loss.

  • ???? Pro Tips:

    1. Be Aware of Your Surroundings: Shimming devices are often used by thieves to steal credit card information from card readers. Always keep an eye on your environment and look for any suspicious individuals or activity around card readers.

    2. Check for Signs of Tampering: Shimming devices are small and often fit seamlessly into the card reader. Always check the card reader before inserting your card. Look for any signs of tampering or unusual or protruding objects from the reader.

    3. Use Contactless Payment: If possible, use contactless payment options such as Apple Pay or Google Wallet. This will eliminate the need to insert your card into a reader, which eliminates the risk of shimming.

    4. Keep an Eye on Your Bank Account: Regularly monitor your bank account for any unauthorized transactions. If you notice anything suspicious, contact your bank immediately and report the activity.

    5. Educate Yourself: Keep yourself informed about new scams and tactics used by cybercriminals. Stay up to date with the latest security measures and always take necessary precautions to protect yourself from cyber threats.

    Introduction to Shimming Devices

    The use of payment cards has been prevalent in modern society, and with time, advancements in technology have led to the development of newer and more secure payment methods. The introduction of Europay, Mastercard, and Visa (EMV) chip technology was meant to reduce the incidence of fraudulent activities resulting from skimming operations. Skimming involves the copying of magnetic stripe data from payment cards, which are generally vulnerable to fraud. However, cybercriminals have adapted to the change in technology by introducing shimming devices.

    Differences between Shimmers and Skimmers

    Although shimming and skimming operations share some similarities, there are significant differences between the two fraudulent activities. The primary difference lies in the technology used to perpetrate the fraud. Skimming involves extracting data from a payment card’s magnetic stripe, whereas shimming involves accessing the chip. Shimming devices are much smaller than skimming devices and require a certain level of expertise to install.

    How Shimming Devices Work

    Shimming devices are made of thin, small, and flexible materials specifically designed to match the dimensions of EMV chip readers. The devices are slid into the card slots of payment terminals and are virtually invisible to the untrained eye. Shimmers work by receiving data from the EMV chips, which are then transmitted to a remote device owned by the cybercriminal. A commonly used method of transmitting this data is through the use of Bluetooth technology. Once the cybercriminal has received the data, they can use it to create cloned cards that can be used for fraudulent activities.

    Detection and Prevention of Shimming Attacks

    As shimming devices are almost invisible, detecting them can be quite difficult. However, there are indicators that can alert security personnel to the presence of shimmers. First, unusual error messages or the inability to read a payment card should raise suspicions. Secondly, if there is a problem with an EMV chip, such as it not being read, there is a need for further investigation as it may be due to a shim.

    • Cybersecurity experts recommend the following measures to prevent shimming attacks:
    • Regular inspection of payment terminals and card readers for any signs of shimming devices
    • Updating payment technologies regularly
    • Encryption of all data transmitted between a payment card and the payment terminal
    • Tightening strict physical security around payment terminals to ensure installed shims are detected

    Impact of Shimming on EMV Microchip Technology

    The availability and use of shimming devices has resulted in the question of the effectiveness of EMV microchip technology as means of protecting payment cardholders from fraud. Cybercriminals are able to manipulate the system and extract data from even the most secure payment terminals. The use of shimming devices has also highlighted a possible weakness in the security design of EMV microchip technology, and further improvements are necessary to prevent further losses through fraudulent activities.

    Examples of Shimming Attacks

    There have been several cases of shimming attacks across the globe, resulting in significant financial losses. In the United States, a large number of shimming attacks have been reported, with an instance where nearly 2000 payment cards were cloned by cybercriminals. The criminals had installed shimming devices at multiple petrol stations, which enabled them to extract card data. In Canada, reports cite the use of shimming devices in high-end stores in the Montreal area, where chip data was stolen and later used to create clones.

    Future of Shimming Technology in Cybercrime

    As advancements in technology progress, cybercriminals will likely continue to refine shimming devices and utilize them in fraudulent activities. Chip-and-PIN technology, though useful, may not be enough to prevent shimming attacks. Therefore, there is a need for further development of security measures that take into account the evolving techniques used by cybercriminals.
