Types of Skimmers
Skimmers are devices designed to steal credit card information. There are several types of skimmers, each with its own method of operation and level of sophistication. In this article, we will explore the different types of skimmers and how they work.
Overlay Skimmers
Overlay skimmers are the most common type of skimmer and are typically found on ATMs and gas pumps. These skimmers are made to look like a regular card reader, but they are placed over the legitimate reader to capture the card information. Overlay skimmers may also have a small camera installed to capture the user’s PIN as they enter it on the keypad.

Insert Skimmers
Insert skimmers are installed inside the card reader, making them difficult to detect. When a card is inserted, the skimmer reads the card’s magnetic strip, capturing the information. This type of skimmer is commonly used on point-of-sale (POS) systems, where customers swipe their cards to make a payment.

Bluetooth Skimmers
Bluetooth skimmers are a more advanced type of skimming device. These skimmers are connected to the card reader wirelessly via Bluetooth technology. Once installed, the skimmer can capture the card information and transmit it to the attacker’s device, which is located nearby. Bluetooth skimmers are highly discreet and difficult to detect.

Shimmer Skimmers
Shimmer skimmers are a newer type of skimmer that targets chip-enabled credit cards. Unlike skimmers that target the magnetic strip, shimmers are designed to fit inside the card reader and intercept the data exchanged between the chip and the card reader. This allows them to capture both the card information and the PIN entered by the user.

Gas Pump Skimmers
Gas pump skimmers are specifically designed to target fuel dispensers. These skimmers are usually installed inside the pump, making them difficult to detect. When a customer inserts their card to pay for gas, the skimmer captures their card information. Gas pump skimmers are a growing concern due to the prevalence of card payments at fuel stations.
