I’m not a fan of carrying around loyalty cards: in this day and age, it seems like we should be able to somehow have that information stored on our cell phones or one master card.
when you sign up, you’ll be asked to link a credit or debit card to your passport account. paying with the passport charges your credit or debit card, so you can order, pay, and earn rewards (and redeem them automatically!) in one easy step. boom! you’re good to go.
Call me paranoid, but I am leery of having a business store my credit card information on its servers permanently, and am even more leery of having that information somehow accessible from my phone. Not that I’m worried about a phone thief running up a burrito bill, per se, but this is the kind of thing I like to nip in the bud.
