yeah I know most companies will cover your ass if your number gets stolen but there is just something about it that seems insecure. I don't really use credit anyway. cash is king
Most if not all credit card services, if you call them, will offer you a temporary credit card number. It ties back to your main account but its authorized in a smaller amout or a one time charge so you can use that 'fake' number at online retailers and it goes back to your account. If someone steals that 'fake' number and tries to use it, its one time use is up and its declined.
