What is Wiegand Technology?
Wiegand refers to the trade name given to the technology commonly used in card readers or sensors. The technology works through a Wiegand interface that consists of three wires that operate between the reader and the controller. Out of the three wires used in the Wiegand interface, one is common ground while the other two are for data transmission.

4. What Is A Wiegand
Card Reader?
A Wiegand card reader is nothing
but a device that uses a Wiegand
interface.
It arose from the popularity of
Wiegand effect card readers
developed in the 1980s.
5. What Is A Wiegand Effect?
Shell &
Core
Wiegand effect is a pulse generating phenomenon
in a special alloy wire that leads to creation of two
distinct magnetic regions in the same wire. In
technical terms, these two magnetic regions are
called:
These two distinct magnetic regions then react
uniquely to the magnetic field created.
6. What Is A Wiegand Pulse?
When two magnetic regions Shell &
Core change to different polarity
orientation then the Wiegand pulse is
generated.
This pulse is then sensed by the reader.
7. What Is A Wiegand Card?
A Wiegand card is a regular card which is
embedded with a Wiegand strip that
contains information.
This strip contains small pieces of
specially processed wires and is
covered through lamination under
pressure to create a solid vinyl card.
8. Types Of Information Readable
By A Wiegand Card Reader
Medical histories
Bank account numbers
Credit card numbers
Criminal records
Employee identification information
A Wiegand Card Reader works by reading
the wire-made strip embedded on a card.
It can read information like:
1.
2.
3.
4.
5.
9. Wiegard Technology Used
In Access Control Systems
Wiegand technology in access control
solutions is commonly used as an interface
between RFID readers and access control
equipment.
It is because of the safety offered by
Wiegand technology that it is commonly used
in access control systems.
