To register a Starbucks card, visit the Starbucks website to create an account, then follow directions to register the card using its unique identifying card number. The registration form asks for your name and email address, and requires you to choose a password.
After registering the card, you can receive all the advantages that come with a reward card, which includes free food and drink rewards, early access to new Starbucks products, free iTunes downloads and special discounts. You can make payments from your smartphone if you download the Starbucks mobile app.
To enjoy the free food and drink rewards, you need to earn Stars. You get one star when you pay with your registered Starbucks card, or when you use the mobile app at stores that accept payments through the Starbucks mobile app. You can also earn stars when you buy specially marked Starbucks products where you purchase groceries. The more stars you collect, the more rewards you can earn. Once you have registered your card, you can track the stars you've earned online or through the mobile app.
Every time you've earned a reward, you'll receive an email. There are different levels of rewards that are based on the number of stars you have accumulated.
