SECURE YOUR DATA

Since the beginning, smart cards have been considered closed proprietary products understood by only a handful of technical gurus. The idea behind this article was to demystify smart card technology and encourage you to trust the SIM card, not just as an authentication token, but also as a secure, reliable platform for storing personal data such as telephone contacts. After you understand the basis of the SIM technology, you can devise new applications with the help of advanced tools such as the SIM application tool kit.

In addition to learning about SIM smart cards, you now know how to enter numeric information without a dedicated keypad with the help of an ADC. You can also exchange information back and forth with the Windows Address Book with the help of a Renesas M16C62P microcontroller. Good luck with your next project.
