Credit card skimming is one of the most common forms of financial fraud worldwide, and India has not been spared. From ATMs in busy marketplaces to point-of-sale machines in shops, criminals have found ways to secretly copy card data and use it for unauthorized transactions. Understanding how it works is the first step to protecting yourself.
What is Credit Card Skimming?
Definition and Overview
Credit card skimming is the illegal capture of card information using a hidden device. The data stored on the magnetic stripe of a debit or credit card is copied and later used to make cloned cards or fraudulent online transactions.
In other words, when you swipe your card at a compromised ATM or POS machine, you may unknowingly hand over your sensitive details to fraudsters.
Meaning of ‘Credit Card Skimming’ in some of the Indian Languages
How Skimming Works
Fraudsters install skimming devices on ATMs, payment terminals, or even online websites. These devices copy the data from the magnetic stripe, and sometimes hidden cameras or keypad overlays are added to capture your PIN.
Unlike phishing, which relies on tricking users, skimming is a silent theft that often goes unnoticed until you see unfamiliar charges.
How to explain ‘Credit Card Skimming’ to kids?
Think of your card as a key. A skimmer is like someone secretly making a copy of your key while you’re using it. They can then use the copy to open your “money locker.” To stop them, always cover your PIN, check for strange devices on ATMs, and keep an eye on your bank messages.
Common Types of Skimming Scams
ATM Skimmer Devices
Criminals fit fake card slots or overlays on ATMs to steal card data.

How ATM Skimmer Devices Are Installed
- A false front is attached to the ATM card slot.
- Hidden pinhole cameras are placed to capture PIN entries.
- The stolen data is cloned to make duplicate cards.
Point-of-Sale Card Skimmers
Fraudulent merchants or tampered POS machines capture card data during payment.
Contactless Card Skimming
With NFC technology, fraudsters may try to capture data wirelessly. However, the risk is relatively low since most banks use tokenization and limits on contactless transactions.
Online/Digital Skimming
Also known as “formjacking,” this involves malicious scripts injected into e-commerce sites to steal card details entered during checkout.
Digital Skimming: E-commerce Risks
Unsecured shopping sites may be compromised, allowing hackers to skim thousands of card numbers at once.
