Project Introduction: Recently libraries have been extending beyond the physical walls of a building, by including material accessible by electronic means. Library 2.0, a term coined in 2005, is the library's response to the challenge of Google, and an attempt to meet the changing needs and wants of the users, using Web 2.0 technology. Some aspects of Library 2.0 include, commenting, tagging, bookmarking, discussions, using social software, plug-ins, and widgets. Inspired by Web 2.0, it is an attempt to make the library a more user-driven institution.

System Requirements: One of Korea's top vending machine makers wanted to leverage RIFD (Radio Frequency Identification) to design a modern Self-Service Book Borrowing and Returning System.

The idea was that customers reserve a book through the library's website, choose the location to physically pick up the book, and the computer would provide the customer with a special bar-code that they should print out and bring with them. The customer then simply goes to the assigned location, shows the printed bar-code information to the vending machine, and the reserved book would show up automatically.

Customers could also return the book to any applicable vending machine, and due to the fact that all books are tagged with an RFID, the library's website and vending machine system can deliver and trace all the books automatically.

To complete this project, they required:

• Compact digital I/O modules with a built-in wiring terminal block
• Easy to mount
• Had a firm cable connection

Project Implementation:

USB-4751: 48-channel digital I/O USB module

USB-4622: USB hub

System Description: In this solution, the USB-4751 is setup to control the drawer switches when the information is retrieved from the bar-code/ RFID readers. Alternately it can sense which drawer is not occupied for customers to return their books. The USB-4622 acts as a USB hub to gather all the necessary information. The industrial display interacts automatically with customers, which is considerably timesaving and cost-saving.

Conclusion: This system is the first library 2.0 system in Korea, and was integrated with the Amazon business model, RFID and vending machine technology. Not only was the manufacturer able to save cabling and installation efforts, but also a lot of maintenance effort by leveraging Advantech's DiagAnywhere utility. All of the vending machine's operations can be monitored remotely from the central control room.
