There is no charge to register for the MyPanera Rewards program, with or without a physical card. To do so, visit PaneraBread.com and click on the MyPanera tab. Click on the Join Now tab that appears, and follow the prompts to start earning rewards.
MyPanera Rewards do not involve coupons or points, as of 2015. Instead, the card simply tracks how often the customer visits a bakery-cafe, and rewards are earned based on the number of visits. A phone number can be provided to the salesclerk or typed into Panera Bread's system to make use of the program without a physical card. In addition, missed visits are recoverable by typing in the 22 digit number on the bottom of the receipt while logged into the MyPanera program. Physical cards are available at any Panera Bread location, including the option to transfer an existing account with no plastic card into one with a card.
