Can Starbucks electronic coupons be intercepted?

I can't. Starbucks official website shows that the screenshot of Starbucks electronic coupon cannot be used. Barker is a coffee brand, which is popular among young men and women at present. In order to give the people the biggest welfare policy, Starbucks will give everyone a virtual star card, which can only be logged in on one device, but can't be used. Screenshots can also be used by others, which will harm the interests of Starbucks.
