Many consumers have received new credit cards in the mail over the last year - most of them with an implanted chip that increases security by generating a unique code every time you use it.
However, not all merchants have activated chip readers, and crooks are still able to steal credit or debit numbers through "skimming," hacking into databases or compromising small business payment systems.
Skimmers are devices placed on ATMs, gas pumps and other public places that can read your card's details when you swipe it. Thieves can then copy your data onto a bogus card, which they use to run up a big balance or drain your bank account. When you use a public ATM, look carefully to see if anything has been placed over the card reader. If it has, do not use that terminal.
Better Business Bureau urges consumers to examine monthly statements carefully to spot any purchases they did not make. If you have online access to statements or accounts, check those in between monthly statements, especially if you suspect unauthorized activity on your account. Notify the card issuer if you spot anything suspicious.
Other precautions you can take to protect your credit and debit cards include:
Shred all statements and applications you get in the mail that you do not need to keep, such as credit card applications, insurance forms, financial statements, health forms and utility bills. Consider getting bills online, but make sure you still have access to statement details.
Change your passwords regularly, and do not use the same password for all your accounts. Avoid using your birthdate or address in your password. Use a combination of numbers, symbols and upper and lower case letters.
Avoid making purchases or checking financial accounts when you are on public Wi-Fi networks. Hackers often scan such networks in hopes of finding information they can use to commit fraud.
Do not open suspicious texts or emails, or click on links in unsolicited emails or texts. These can be loaded with computer programs that can steal usernames and passwords from your computer. Delete the message. If it appears to be from a legitimate source, hover over the email address to see if it corresponds to that source or go to the appropriate site online and access information there.
