John M, Spencerport, NY:
The safety of generating a one-time use account number for internet purchases, helps in keeping my credit account secure. The Cash Back Bonus is like having dessert afterwards. Additionally, seasonal 5% Bonuses awarded on specific purchases help me time purchases for maximum cash back.
Since first becoming a Discover Card user in 1986, the Convenience, Security, -and Cash Back Rewards keep Discover my credit card of choice.



The only problem with the one-time nu,bers is if you order something online for store pickup (like BestBuy etc). Usually they ask to see the card. Which doesn’t have the same number as the transaction.
I’ve had to explain the “Secure Number” concept to about 20 different people at various stores. Most have never heard of the ability to do this. Don’t know why this is. It’s a great idea.
