How to Increase Your ATM Password IQ, by Nationwide Automated Systems Staff Writer

Question: How many four-digit combinations can be created using the standard 0-9 digits available for most ATM cards?

Answer: 10,000. 

Given this fact, many people might assume that the distribution of PINs would fall out fairly evenly, reducing the chances of a skimmer discovering the PIN to a random card. 

Nevertheless, nearly 30 percent of cardholders choose the most easily guessed PINs available, according to DataGenetics, a research group. Potential skimmers can crack this group of numbers by employing just 20 combinations. The most popular password remains 1234, capturing nearly 11 percent of PINs in use.

So if this is your PIN, experts recommend changing it as soon as possible. 

Next, avoid patterns. Straight or diagonal lines allow skimmers to play a kind of “bingo” game to find a password. ATM cardholders should also avoid repeating numbers.

Researchers also recommended avoiding even numbers. For example, users preferred the numbers 2468 much more than 1357. The exception to this rule is when the odd numbers appear to indicate a year. Thus, PINs starting with 19 may be easier to hack. In fact, PIN numbers beginning with 19 occur in the top-20 percent of options, DataGenetics found.
