PSA – Every time you post a photo of your credit card god kills a kitten.

PSA – Every time you post a photo of your credit card god kills a kitten.

I know its exciting when you get that new debit / credit card. It has that cute photo of your dog, or maybe your kid or even your favorite sports team. And I know it’s hard to contain your excitement to just your friends and family that are within arms length and all you want to do is show the world. So you post a pic of it on twitter or facebook or name any other social networking service. Now someone has your card number, full name, photo and probably knows a lot about your habits (thanks to you posting it on twitter).

There is even a dedicated twitter account for retweeting such photos. Check it out and before you start pointing fingres at the NeedADebitCard twitter account remember they are just retweeting what people have already posted publicly.

Though this also applies to concert tickets or anything else with a barcode / serial number. You should never post that stuff online. It’s less of an issue after the event is over but if its a season ticket holder account number someone could use that to hijack your account.

Circuit City wants my SSN

I recently made a purchase from Circuit City, it was for under $100 dollars. And I saw this message at the “Thank You for your purchase” screen.

Circuit City wants the last 4 digits of my SSN

I can’t imagine why but for some reason Circuit City wants to know the last 4 digits of my SSN. They claim its to identify me and expedite my order. I guess my Name, Mailing Address, Billing Address, Phone Number, Email Address and Credit Card number isn’t enough to identify me. There is no chance in hell I would give Circuit City or any other business (except a financial institution) my social security number.

You should always question when a company wants to know any personal information about you. Don’t just hand it over. Just think of the security questions you get asked when calling your bank or credit card company. Whats your birthday? Mothers maiden name? Name of your first pet? Last 4 digits of your social? Some of this information can be found in public record and the rest right from Facebook. Well almost, hopefully your social security number is listed on Facebook.

All I am saying is be careful who you give your information too and what information you give them. Keep a list of places that have your information and what information they might have. This way you will know what was leaked when the company reports that it “lost” a laptop with your information on it.
