Book lending for air travellers

I was thinking of creating a book lending business in airports for travelers on long flights. Instead of buying the book in the airport bookshop the passenger can borrow it only for the course of the flight by having the credit card charged full retail price of the book. Upon arriving in the destination airport the passenger returns the book and gets full refund in their credit card. The book can then only be re-lent to passengers traveling back to the country airport the book originally came from.

If a passenger really likes the book they will have the option to buy it by simply keeping it. In this case a new order to re-stock the book will be automatically made via the system and a small profit realized from having sold it retail price. People can also donate books in this business and if their used-book is sold they get to keep a portion of the profit.
