RS485
The RS-485 bus standard is one of the most widely used physical layer bus designs in
industrial applications. The key features of RS-485 that make it ideal for use in industrial
communications and the applications are
•
Bi directional communication in the single pair of twisted cables
•
Multiple Driver can be connected to the same bus
•
Differential communication makes it work for long distance upto 3000 feets or
approximately 900 meters (depending on the cable and environment)

SMARTCARD
A
smart card
,
chip card
, or
integrated circuit card
(
ICC
) is any pocket-sized card with
embedded integrated circuits.
The benefits of smart cards are directly related to the volume of information and applications
that are programmed for use on a card. A single contact/contactless smart card can be
programmed with multiple banking credentials, medical entitlement, driver’s license/public
transport entitlement, loyalty programs and club memberships to name just a few. Multi-
factor and proximity authentication can and has been embedded into smart cards to increase
the security of all services on the card.
