The rate of changing the PINs is lesser than the average marriage in the UK, which lasts for 11.5 years, the report said.
The research surveyed more than 2,000 UK consumers.
The habit of not changing password is due to people’s lack of confidence in PIN as a security measure, with 40% respondents saying that it is not a safe way to log into an ATM.
Intelligent Environments chief technology officer Clayton Locke said: "With so many passwords to remember, no one wants to keep changing their four digit ATM codes.
"Unfortunately this increases the risk that a criminal could gain access to your accounts."
Some of the most common forms of card scams include card skimming through devices, card-trapping devices and shoulder surfing, where scammers distract customers while entering the PIN number.
According to Intelligent Environments, banks can combat these risks by enhancing authentication measure at their ATMs.
Locke said: "Mobile banking usage has more than doubled in the past year, while biometric security is becoming an increasingly viable technology to leverage.
"There’s a great opportunity for banks to employ second factor authentication using these methods, for example by installing fingerprint scanners on their cash machines, or enabling remote identification through a smartphone. These could help give customers a far more enhanced and secure banking experience, regardless of whether they change their PINs."
