I've used only Online banking for years. I even had to ask someone the cost of a postage stamp. I haven't "mailed" anything for years! ....except the occasional pre-paid envelopes. I use a secure Online purchase program that Discover card has. For each purchase, it generates a "new" credit card number that is in turn tied to my real number.....but NEVER gives out the REAL number!!! I've used it for even more years than Online banking. If there were to ever be an issue with a number given to a website, that number would be tied back to ONLY that site!! With both the banking and Onlin
