After purchasing your digital Key Tag, it will be accessible within the Offers section of the Wendy’s app. To use it, just place a mobile order and then apply the offer.   For in-restaurant or drive-thru orders, the Key Tag offer can be uploaded to your Wendy’s Rewards card. To do this: Open the app. Look for the navigation bar at the bottom of the screen and tap “Scan”. Tap “ADD OFFER TO MY CARD”. Find your Key Tag offer and tap on it. Tap on “LOAD TO CARD”. Make sure you include a Jr. Frosty as part of your in-restaurant or drive-thru order and have a crew member scan your Rewards card to apply the offer.
