Going digital.....

 A more full-fledged digital vending machine would also house e-books and audiobooks!!! With an option to print out low resolution copies of the publications. Or how about incorporating an automated internet radio station with audio output(sometimes with a real DJ participation) delivered through headsets/earphones? Regular vending machine customers can be entitled to loyalty club VIP memberships with graded tiers...Higher tiers can come with reward of mystery physical gift delivery to customers' homes or P.O. Boxes...Machine can also accept gift card payments and tokens, coupons, etc. but only higher tiered customers can pay by credit/debit cards to prevent fraud and identity thefts.
