Glossary

Transaction – A Transaction is any kind of event recorded at a Hand Reader.

Transactions may include actions such as accepted or denied hand reads, input and

output events, and doors opening and closing.

Wiegand™ Reader – The term “Wiegand Reader” has two meanings depending upon its

application. A true Wiegand reader reads a specially constructed card made up of small

pieces of magnetic wire. As the card is swiped through the reader, the individual bits of

wire generate a unique data signal. This data signal is made up of a Facility Code ﬁeld

(typically 8 bits), an ID Number ﬁeld (typically 16 bits), and parity bits (typically 2 bits)

for a total of 26 bits of data. Now this 26-bit Wiegand data format has been adopted by a

variety of access reader devices and access control panels for transferring user access

data.
