A Brazilian publisher expanded their Ticket Book program to include an RFID card pre-loaded with 10 subway rides into select books. Passengers need only scan their books at the subway turnstyle to ride for free. When the 10 rides expire, the books can be recharged online.

Current Ticket Book titles include Peanuts: Friendship. That’s What Friends Are For by Charles M. Schulz, Garfield: Sorry by Jim Davis, Hundred Love Sonnets by Pablo Neruda, The Great Gatsby by F. Scott Fitzgerald, The Art of War by Sun Tzu, Sherlock Holmes: The Hound of Baskerville by Sir Arthur Conan Doyle, Hamlet by William Shakespeare, Murder Alley by Agatha Christie, Chives In Trouble! by Mauricio de Sousa, and Quintana Pocket by Mario Quintana.
