Or at least some of it is.

If you have the Nexus S 4g from Sprint and you have a Citi-MasterCard, you use Google’s newest app, Google Wallet. On Monday Google rolled its new mobile payment app that will allow users to tap and swipe to make purchases without pulling out a credit card. In it’s first phase, it will only work in conjuction with a Citi-MasterCard or you can add money to a Google Prepaid Card from any of your exisiting credit cards.

Although there is a lot of excitement about the product launch there is of course some skepticism that comes along with new technology. The biggest risk right now has to do with the 4-digit PIN that needs to be entered when using the app to make a purchase. Do you know how long it would take a hacker to crack a 4-digit PIN? A couple of hours, maybe a day? Sara Yin of PCMag.com tells us that by using a brute-force attack and going through different permutations it would only take 18 minutes. However, to crack a 6-digit alphanumeric PIN it would take 8 years. Makes me wonder why Google would choose the  higher risk PIN option and leave our credit cards so vulnerable.

Do you think it’s risking to have your credit card information on a mobile app?
