    What changes to contactless standards and technology are expected in the future?

    Many vendors are actively developing new technologies to address the increasing market need for secure contactless technologies for a wide variety of applications. Changes in government regulations will also provide opportunities for enhancing contactless technology performance. It is important to note, however, that standards development is a lengthy process so it takes time for new technology developments to be reflected in standards that help to drive the availability of interoperable solutions. A few examples of new technologies that are expected include:

    • Changes to technology based on the ISO/IEC 15693 standard. Contactless cards supporting the ISO/IEC 15693 standard currently operate at 1.65 Kb/sec to meet FCC limits on sideband power in this frequency range. The FCC is expected to lift its restriction in late 2002, which would allow cards based on the ISO/IEC 15693 standard to improve their data rates.
    • Changes for higher speed operation. ISO working groups plan to add higher speed modes of operation to ISO/IEC 14443. This will increase the speed supported by this standard from 106 Kb/sec to the 848 Kb/sec that has already been demonstrated by IC manufacturers.
    • Alternative access control reader networking solutions. Wireless readers offer a significant advantage in lower costs of installation, particularly in older facilities. New security approaches can ensure strong authenticated channels between hosts or panels and new wireless readers. IP readers also permit direct connectivity to LANbased management and control applications.
    • The ability for a single contactless chip in a card to operate in full ISO/IEC 14443 and ISO/IEC 15693 modes.
