Using an ATM is a very convenient way to access your bank account. Unfortunately, it is also a very convenient way for scam artists to access your bank account as well, often with your assistance.
The primary way ATM’s are compromised is through the use of a small device called a “skimmer” which fits over the slot where you put your bank card. The skimmer reads the information embedded in your card, which is half the battle to accessing your account. Often criminals will install cameras by the ATM to read your PIN as you input it into the ATM. These cameras may even appear to be the security cameras used your bank. Other times they may even install a keyboard over the regular keyboard to capture your PIN.
Always check an ATM before using it to see if it appears to have been tampered with and when you input your PIN, shield the keyboard from any cameras or prying eyes.
