I am using smart card but I am not planning to sell it. Know why? Because smart cards are convenient to carry and easy to use. They assure protection of data stored on them and offer user authentication facilities.

Personally, I used EncoreViewer and a Smart Card. I used this two to view and print the therapy data generated from your Respironics sleep therapy device. As we all know, EncoreViewer reads the patient's Smart Card and displays detailed compliance and therapy reports.
