Proximity Architecture
The card communicates to a reader through radio frequency.
Passive cards are activated by the reader itself.
5. Card Readers
Proprietary vs. non-proprietary:
Proprietary readers are those that are manufactured by the access
control OEM.These readers have proprietary communication between
the host and the panel.
Non-proprietary readers work on an open standard.Wiegand is the
open standard.Nearly all manufacturers accept this protocol.
6. Complete Card and Reader Line
Wide variety of readers
Many sizes and styles
Color choices
Multiple reader outputs:
Wiegand standard
Clock and data
Serial outputs
(RS-232, RS-422, RS-485)
7. Active Vs. Passive Cards
A passive card is a card without a battery. The advantage of a
passive card is longer card life.
8.
Single Technology Solutions
Access cards can function as photo ID badges.
Access cards can have multiple technologies:
Proximity
Wiegand
Mag stripe
Contact smart chips
Contactless smart chips
Bar code
Junk stripe for debit applications
9. Card to Reader Communication
HID readers pass data from the card to the host
HID readers are open to all card formats
10. Wiegand Data Interface
A widely used Access Control industry standard
The Wiegand interface is a binary code that consists of data lines
called Data 0,Data 1, and Data Return. Toggling the respective line
to ground (or Data Return) for a specified time sends data.
The data is a series of ones and zeros that can be partitioned to
suit the needs of the system.
11. Panel Format Settings
Access Control Panels are built to accept data in specific
formats.
Most use the standard, industry format of 26-bit.
Simple panels might accept one or two formats
Sophisticated panels are software configurable and accept hundreds
of different formats
The panel will also determine the type of reader to panel
transmission used.
Most common is the Wiegand communications protocol
Also used is:
12. Serial interface (RS232, RS422, RS485)
