Chip & PIN Fraud Explained - Computerphile

TL;DR

Chip & PIN cards were introduced to prevent fraud, but criminals have found various ways to cheat the system, including intercepting transactions, stealing card details, and manipulating transactions through electronic devices.

Transcript

In the old days cards from the 1960's had a magnetic strip right so that when you did a transaction the terminal would read the data on the card's magnetic strip but from 2003 in the UK you started to get chips as well. So the information is kept in this semiconductor chip and that makes it significantly more difficult to counterfeit. . To counterf... Read More

Key Insights

• 💨 Chip & PIN cards were introduced to counter fraud, but criminals quickly adapted and found various ways to cheat the system.

Questions & Answers

Q: How did chip & PIN cards make counterfeiting more difficult?

Chip & PIN cards replaced the magnetic strip on cards with a semiconductor chip, making it significantly harder to counterfeit. Copying a magnetic strip card is simple, but counterfeiting a chip requires expensive equipment and drilling into the card to extract keys.

Q: Did fraud rates decrease after the implementation of chip & PIN?

Fraud from counterfeit cards initially decreased after chip & PIN was introduced. However, criminals quickly found ways to harvest chip & PIN details using compromised terminals, leading to an increase in fraud rates.

Q: What are some examples of chip & PIN fraud tactics?

Examples include using false terminals to intercept transactions, installing dodgy equipment in card terminals to capture chip & PIN details, and using devices to trick terminals into accepting PIN-less transactions.

Q: How do criminals manipulate transactions to carry out fraud?

Criminals can insert devices between the card and the chip & PIN terminal that modify the transaction flow. They can deceive the terminal into thinking the PIN was correctly entered and inform the card that a signature verified the transaction, enabling no-PIN fraud.

Summary & Key Takeaways

• Chip & PIN cards were implemented in the UK in 2003 to combat fraud. The introduction of chips on cards made counterfeiting more difficult.

• However, fraudsters quickly adapted, resorting to online fraud and using chip & PIN devices to harvest card details and create counterfeit mag stripe cards.

• Criminals also found ways to cheat by manipulating transactions, using devices that disguise PIN verification as signature verification.
