If you have an access control system or if you work with access control systems you often hear the terms: Wiegand format, Wiegand data, Wiegand interface, Wiegand cards and readers. As manufacturers of inline card encoders and software for access control for over 15 years, DigiOn24 Engineers and Technical Support personnel are experts on Wiegand formats. So what is Wiegand Technology, what are Wiegand Formats and why are they important?
The new Multi-Format capability also allows a clean, elegant Single-Card Solution for the merger and consolidation of multiple access control systems with different data formats and numbering schemes. John R. Wiegand was an engineer who discovered and developed the capabilities of a specially treated ferromagnetic wire, which emits an electrostatic pulse when moved through opposing magnetic fields.
He patented Wiegand wire in In the early s, there were two dominant card technologies in the electronic access control industry: Barium Ferrite BaFe and Magnetic Stripe. The readers were unreliable, requiring constant maintenance, and neither technology worked well in harsh weather or dusty environments. They had manufacturer-specific proprietary interfaces and data output formats. Mag Stripe cards were easily scratched, and easily copied.
So, when Wiegand cards and readers were introduced, the access control industry was eager to make a change. The advantages of Wiegand technology included:. Because of these advantages, dealers and system integrators demanded Wiegand readers. Access control panel manufacturers were forced to develop Wiegand adapters for their control panels which previously had proprietary BaFe or Magstripe interfaces and eventually all panel manufacturers standardized on Wiegand inputs.
These newer technology readers have microprocessors, and are capable of processing the card data before sending it to the control panel. When most people today talk about Wiegand cards and readers, they are not thinking about a card with wires or a swipe reader. Some readers and panels have a single wire for LED control, and some readers are programmable to change the function of this input.
Some readers do not have a Beeper input or a Hold Input. Hold is an optional input, usually connected to a loop detector output for vehicle entrances, and when grounded, it buffers the data output of the reader until released. In the Wiegand communications protocol, the data pulses flow from the reader to the control panel as a continuous stream of bits. Wiegand swipe readers transmit the data, exactly as encoded into the card — there is no decryption or processing of the data by the reader.
The panel interprets the pulses on the Data1 and Data0 inputs and converts them to a binary number, and then to decimal numbers for processing, display and for transaction records. In some cases, the data may be encrypted when encoded, in which case the control panel will also decrypt the data.
The original Wiegand format had one leading parity bit, 8 bits of facility code, 16 bits of ID code, and a trailing parity bit for a total of 26 bits. Eight binary bits allow up to different facility codes to be assigned.
User ID is used to differentiate between individual cards in the system, and each ID number is assigned to a cardholder in the system database. Parity is a simple method for checking data integrity by counting the number of 1s in the bitstream.
The first Even parity bit is calculated from the first 12 bits of the code and the trailing Odd parity bit is calculated from the last 12 bits. The control panel calculates the parity bits from the card data and compares them to the parity bits encoded in the card data.
Parity was originally included to indicate a misread to the control panel, which could be caused by swiping the card too fast, or backward, or by not keeping the card level in the slot, etc. Parity bits are either 0 or 1. The facility code ranges from 1 — , and the Card ID ranges from 1 — , At the control panel, the raw Wiegand data from the reader is converted to decimal numbers.
The typical control panel is programmed to check the bit format, parity, and facility code against information already configured in the panel. If any of these are incorrect, access is denied and the appropriate error code is logged and transmitted to the host system. Systems vary widely — some systems can accept multiple Wiegand formats, some systems can accept any format, and some systems can only accept a proprietary format.
Some systems can store the entire bit stream as a unique number, without checking format, parity or facility code separately — they just search their database for an exact match to the Wiegand bit stream.
Many access control system manufacturers adopted Wiegand technology, but were unhappy with the limitations of only 8 bits for site codes and 16 bits for card numbers , so they designed their own formats with varying complexity of field numbers and lengths and parity checking. Some manufacturers added data fields such as a 4-bit OEM code to differentiate between cards sold to their resellers as in the popular bit Wiegand format. Manufacturers also devised more complicated Wiegand formats by using encryption, intermixing the ID and facility code bits, and developing extremely complex parity schemes.
While these techniques enhanced security, they were developed primarily to prevent new dealers from taking over systems, or selling replacement cards into existing systems by making the format proprietary and difficult to interpret. Sensor Engineering protected these proprietary OEM formats, and would not sell proprietary cards to anyone except the OEM who owned the format, nor would they divulge the format information to anyone. The physical size limitations of the card dictated that a maximum of 37 Wiegand wires could be placed in a standard credit card-sized ID card before misreads would affect reliability.
Therefore, most Wiegand formats used in physical access control are less than 37 bits in length. The only exception to this rule is the bit format, which is an industry standard.
Wiegand Formats are frequently a mystery to system owners and facility managers. Property managers and facility managers come and go, and records are frequently lost or misplaced. Format information is often not known by the end-user — when they run out of cards, they just call the integrator and ask for 50 new cards.
In many cases the original installer is retired or out of business, so the system configuration is unknown. Panels are frequently set to enable the use of bit cards or to ignore facility codes, allowing new cards to be added to the system without knowing the original format.
Some panel manufacturers will not provide card format information. Fortunately, DigiOn24 has a vast library of existing Wiegand formats, their programming software includes a format analysis tool, and they have also helped system integrators reverse-engineer complex formats.
All cards in a given system should have the same facility code. These cards are typically entered into the system database by using a keyboard wedge enrollment reader available from System OEMs or from DigiOn Non-compatible numbering schemes can be a problem when merging access control systems from different manufacturers.
Wiegand Formats were originally developed to allow the implementation of a new card technology. Later they became complicated when OEMs tried to improve them, and then make them more complicated to keep their cards and readers proprietary. Due to the pervasiveness of Wiegand formats, we will have to deal with them for a long time. Card technology has also advanced significantly in the meantime.
In the future, standardization and more sophisticated data interfaces and data formats will be developed. DigiOn24 will continue to develop card and reader products to help manage and comply with these new and emerging standards.
Prox Formats. Wiegand Formats and Technology A DigiOn24 White Paper If you have an access control system or if you work with access control systems you often hear the terms: Wiegand format, Wiegand data, Wiegand interface, Wiegand cards and readers.
The advantages of Wiegand technology included: The Wiegand reader is a reliable, epoxy-potted, weatherproof unit. Wiegand cards cannot be demagnetized, and they do not scratch or wear out. Wiegand cards and readers are immune to external magnetic fields or RF interference. Wiegand readers can be located up to cable feet from the control panel. The Wiegand electrical interface and the bit data format are standard — customers were no longer required to only buy readers from the original system manufacturer.
A diagram of the bit format H is shown below:. How Card Data is Processed At the control panel, the raw Wiegand data from the reader is converted to decimal numbers.
