Let put some minds to ease here...
I used to work at a large bank in the credit card fraud department. We dealt with all sorts of stolen credit cards, ID theft cases, stolen card numbers and the like. I know I've posted this on here a few times, but I'm more than happy to share...
1.) You are not liable for unauthorized purchases on your credit card.
2.) You are not liable for unauthorized purchases on your credit card.
Yes, I posted that twice for a reason. Your card issuing bank holds the merchant, where the merchandise/services were purchased, liable for the charges. Merchants are supposed to have ways and means to combat fraud/theft, and if they allow charges to go through, then they didn't do their job. The bank will then "charge back" the merchant, with the help of law enforcement/law, in order to get the funds back. You will never have to pay for unauthorized use on your card.
3.) The charges you are seeing are typical. Gas stations, online flower purchases, online high end electronic stores, etc, are all used by people who steal information. Why? They either know they won't be carded/asked for ID when the card is presented, and they won't be asked to sign anything.
The charges you see for $1 (sometimes less) are a total red flag. The perps are "card testing" to see if it's open and active. Once they verify the card is active, they sell it, or use it right away very quickly. You might ask, "Well why doesn't my bank look out for this kind of activity." They do. All of them do. If a purchase goes through like that from a known card testing site, it's blocked, and the card is temporarily shut down until you (the card holder) can be verified/notified.
4.) The perps normally do not have your identity. Most of them time, they only have the card number, the name, and possibly the address. Other than your card number, this information is all public and can be found rather easily; Just FYI. In any case, you probably don't have ID theft, just a stolen credit card number.
5.) You might be wondering how they used a physical card when all they have is your card number. Easy. They use a machine called a "skimmer." This skimmer takes the credit number, and other information, and electronically places it on a blank credit card with a magnetic strip. It's more common than you think.
If you believe that you may have had your ID stolen, contact one of the 3 major credit score companies like Experian, TransUnion, or Equifax, and let them know you would like to place a credit/fraud alert on your account. They will place the alert on your account, and notify the other 2 companies on your behalf. It's a free service. If anyone tries to open a line of credit in your name (another credit card, home loan, car loan, etc) you will be contacted to verify before it is opened.
If you have any other questions or concerns, please feel free to PM me anytime.
