It's Official: Upper Deck Authenticated wants to make sure that every consumer feels confident about the purchase they've made through our 5 - Step patented Authentication Process.

1. Every signing session is witnessed by an Upper Deck Authenticated (UDA) representative. After all, observation is the only way to truly guarantee authenticity.
2. Next, an affirmation of the session is signed by both the athlete and the UDA representative, and is stored in a secure, permanent file.
3. A UDA hologram with a unique serial number is affixed to each piece of signed memorabilia. It's your number. And no other item or individual can claim it.
4. Then, a certificate of authenticity is assigned to your piece of memorabilia. It has a matching hologram which contains an identical serial number to that of the item.
5. And finally, the signed memorabilia is packaged with a registration card so you can officially register the item with UDA.
