Documents are displayed in PDF format by use of Adobe Acrobat. Personal privacy is protected and use of the card as a tracking device is minimised because the library acts as an intermediary between user and document supplier. All transactions on the Internet are secured by means of the smart card through authentication and encryption techniques. Use of a smart card not only allows for payment of documents, but also other applications. By connecting a smart card reader to the photocopier it is currently possible to use the card to pay for photocopies, but it could be used for services such as access control to buildings etc.
Libraries can customise use of the system to their own criteria.
Each library is able to apply its own electronic information access, charging policy and categories of users. All these aspects are managed using the administrator system. During the evaluation, testers found both the client and administrator systems straightforward to use. They liked using the smart card and having two electronic purses. Users also liked the idea of being able to pay for other applications such as photocopies with the smart card.
