What is jitter

Jitter is an anti-skimming technique that distorts the reading of the magnetic stripe by altering the speed or movement of the card as it is swiped or pulled through a card reader or ATM. Jitter is designed to render unreadable, and therefore unusable, any information copied by a map skimmer.

REDUCE jitter

Jitter assists fight map skimmingwhich is one of the many methods by which criminals can obtain credit or debit Card number. In order to copy or “skimme” the number, a person can install a device that copies the information transmitted by the credit or debit card reader or the ATM. These numbers are then used to make fraudulent purchases.

Jitter technology is designed to make it harder for illegal card readers to copy credit and debit card numbers. It is more likely to be found in ATMs and other machines that “take” a credit or debit card for scanning, and is less likely to be a feature of machines that allow an individual to swipe their own map.

The jitter itself is a stutter in the timing of the card draw. This means that when a AT M accepts the card you insert, the device does not save the card at a steady rate and may instead stop and restart scanning. Many skimming devices require a smooth swipe in order to skim numbers properly. Jitter technology does not work well in machines that allow an individual to manually dip into a credit or debit card. This type of swipe feature is usually found in older ATMs, but can also be found in more modern machines.

Jittering is not a foolproof method of fooling a credit card skimmer, but can help reduce the percentage of cards that can be read if a credit card skimmer has been installed.

Jitter technology is one of the reasons why a credit card may not be read when swiped, as the technology can cause problems with both legitimate card readers and card skimmers.

Jitter Effectiveness in a Rapidly Changing Security Landscape

Jitter has been around for over a decade, but its ability to protect financial data isn’t what it used to be. For example, even more than five years ago, BankInfoSecurity, in 2012, an article entitled “3 Reasons Skimmers Are Winning”, challenged the prowess of the technology.

“The anti-skimming feature known as jitter, which uses a stop-start or jitter motion at the card reader to prevent card details from being copied, is a standard feature, but has been defeated,” according to the site.

“Introduced to the US market more than seven years ago by ATM manufacturers such as NCR Corp., Diebold, Fujitsu and Wincor Nixdorf AG, jitter remains the primary technology used by financial institutions to prevent skimming. But jitter is only effective on ATMs with motorized card readers – readers that pull the card, read the data from the magnetic stripe, and then push the card in. The technology is ineffective on machines with dip readers, in which the user manually inserts and removes the card.
