Identity Theft.

Was reading some tips from the bank not too long ago on ID theft. Things like:

if you're able use a credit card online for purchases and not a bank card, since a bank card is tied to your account.

Don't sign the back of your card. Instead, write photo ID required.

If you pay your credit card bill through the mail, don't write your entire account number on the memo line of the check, just the last four digits. The credit card company can tell the account number from the last four and if a thief gets ahold of your check he won't have the entire credit card number.
