Three Students in Miami Ad School have introduced a virtual library shelf for subway passengers, allowing them to read the first 10 pages of a book on their smartphone before directing them to the nearest library, as a way of encouraging the public to visit various branches of New York Public Library.
Although there is no Wi-Fi on the subway, NFC technology is found in many of the latest smartphones. NFC is a wireless, contactless system that uses radio-frequency electromagnetic fields to transfer data between two devices held centimeters apart. Passengers can swipe their NFC-enabled smartphone against a poster and download the first 10 pages of their chosen book free of charge.
When they leave the subway, a map pops up on their phone pointing out the nearest library branches where they can find the full version.
