Evangelism Idea - Pocket Books that Serve as Subway Cards

In the video below, books are given away with 10 free trips on the subway (underground) in Brazil in order to promote reading. The subway scan card is embedded into the back cover of the book, and can be refilled online.

What if this was done with some Christian books? evangelistic literature? In addition to promoting reading, people might find themselves reading about the Gospel sheerly by virtue of having it in their hand while traveling. Granted that many people in the world today are oral-prefered learners, but I would bet that many people don't prefer reading simply because they are not used to it.  Toting a book around in order to use the subway or train or bus might just encourage people to do something they otherwise would not have chosen: read a book.

Reaching such an agreement with public transporation authorities in some places would definitely be a challenge, but this idea seems pregnant with possibilities for both reading and evangelism.
