This International Student Identity Card gives students access to discounted rates and promotions around the world with prices starting at $25. With it, students can get a year of discounted admission in 133 countries, including Regal Cinemas (with a 28% discount on print-at-home tickets) and The Second City in Chicago. Available promotions are listed in the free ISIC smartphone app. Applicants must supply proof that they're students to get the Student Discount Card, but there are additional options for youth (from 13 to 30 years old) and full-time teachers. Sales tax may be charged in some states.
