How to Generate One Time Use Disposable Credit Card Numbers
The recent breach of Global Payments has once again brought the issue of credit card security back into the limelight. While most, if not all, affected cardholders won’t feel any financial repercussions, they might have to deal with a little hassle as cards and card numbers are replaced. This rekindled my interest in a technology, one time use credit card numbers, that gained a lot of popularity the last time we had a huge data breach, when Heartland Payment Systems was hacked in 2009.
I was surprised to find out that so few issuers are offering one time use disposable credit card numbers. From what I could find, only Citi, Discover, and Bank of America offered something like this. They all use technology from the same company, Orbiscom, which was acquired by MasterCard in 2009. American Express used to offer a service like this but discontinued it years ago.

With the total amount of credit card debt now topping
In the dozen or so years of being a financial adult, I’ve never spent much time “working” on my credit score. Neither has my wife. I’ve opened up a few more credit cards than I probably should have in my younger years chasing promotions (and I subsequently closed them, to the chagrin of credit experts!), I have missed payments (before discovering the wonders of online bill pay and good reminders), and had, by chance, a good mix of accounts (student loans, mortgage). My credit score is 780 and my wife’s is 804 (maybe I shouldn’t have opened, or closed, those credit cards!).
