Driver ID Reader Options

Our devices support a variety of Driver ID options to provide driver behaviour monitoring, access control and logbooking solutions. The Dart2, G62 and G120 support driver ID.

If a worksite already has a specific reader or card type in use – chances are one of our devices will be able to read it, enabling a variety of unique, cost effective options, and removing the hassle of reissuing ID cards!

Some 3rd party card types which we are able to be read by our devices include MiFare and HID cards. See here: List of Driver ID readers and solutions for details. Other card types have the potential to be supported if a suitable reader can be found.

Currently, we have seen readers on the market which enable the following tag types to be read by all 3 of the Dart2, G62 and G120:

  • iButton
  • 125 kHz RFID
  • MiFare (13.56 MHz)
  • HID, HID Prox

Additionally, there are a variety of keypads on the market which are compatible with the G120. A keypad is often a preferred driver ID input method - as nobody can 'lose' their tag!

TABLE OF CONTENTS

What is the Wiegand Interface?

The Wiegand Interface is a wiring standard found on card readers and access control systems. It has become somewhat of a de facto standard for such systems.

Wiegand initially caught on in the 1980s due to its ability to support far longer cable runs than other standards at the time. Wiegand swipe cards also do not contain microchips and cannot be magnetically erased, making them durable.

Newer standards have since developed, and you do not see many Wiegand cards in use anymore. However, while the actual swipe card may use a different protocol, many readers have a Wiegand output which is used to send the data to other devices or control systems. 


iButton/1-wire 

Manufactured by Maxim/Dallas Semiconductor, an iButton is a microchip housed in a round stainless steel button (it looks a bit like a coin cell battery). iButtons and their readers require physical contact to function, but they are cheap, rugged and effective.  

Digital Matter stock and supply iButton tags and iButton readers. But a variety of 3rd party readers can be sourced to suit other requirements (like reading MiFare cards with a G62 for example).

iButton readers send their data over a 1-wire interface, developed by Dallas for the tag format. However, it does not mean only iButton tags can be read over 1-wire. In fact, a multitude of readers can be sourced that will read a variety of cards and connect to the 1-wire input on our devices.

These card types include: MiFare, EM4001 125kHz and HID cards.

This is particularly useful as it enables the G62 to read a variety of card types. The G62 is our IP67 rated, rugged vehicle tracker – suitable for equipment and harsh environments. For some applications an IP67 rating is a must.


DM RFID Reader 

We also manufacture an RFID reader, compatible with the Dart2 and G120, which reads 125kHz EM4001 cards. This makes for a convenient out of box solution.  


Wiegand Interface 

As discussed, the Wiegand interface is common in access control systems. The G120 will support this interface. Most card readers that output Wiegand should work immediately with the G120 for plug-and play operation.

RS232 

The G120 also has an RS232 interface. RS232 is a serial interface used for the transmission of data. Any readers that output RS232 can be potentially integrated with the G120, however firmware work needs to be undertaken. This provides another driver ID option. 

Typically if a certain type of card is required to be read, a Wiegand or 1-wire compatible reader can be sourced which is the preferred option due to its plug and play nature.  


What does this mean in practice? 

Many companies utilise swipe cards for their employees to grant them access to buildings, vehicles, or equipment. A large site may have hundreds of employees with swipe cards already issued.  

When rolling out tracking devices into their vehicles, Driver ID is a key requirement.

While our RFID reader is a simple and effective solution in terms of installation and setup – it requires the company to issue and maintain another RFID Fob – which can be quite a task.  

To simplify the solution, a suitable reader that reads the swipe cards already issued and has a Wiegand or 1-wire interface can be sourced. Such readers can work with our devices, meaning the current cards can still be used! 


So how do I work out what reader to get? 

  1. Find out the format of the access cards – the reader must read these. 
  2. Search for readers that read this type of card and check their datasheet to see whether they have a Wiegand or 1-wire output.
  3. Select one that is reliable, a suitable price and form factor.
  4. Connect this reader to the Dart2, G62 or G120 for 1-wire, or the G120 for Wiegand and test with your cards!

Example, searching for readers - we could apply these filters on a site stocking readers when trying to find a solution to reading HID cards with the G62. 

HID is the tag we need to read, and to read this with the G62, the interface available to us is 1-wire.


List of Driver ID readers and solutions

The below is a list of reader solutions which we have come across. Not all are thoroughly tested by DM, resellers should conduct their own testing to ensure the performance is satisfactory. Additionally this list is not exhaustive, there are many solutions available on the market to fulfil various needs.

iButton Tags

Supported Devices - Dart2, G62, G120

iButton tags can be read using these devices. We stock and supply readers and tags, but a variety of 3rd party readers can be sourced.
See: Connect an iButton Reader to the G62, Connect an iButton Reader to the Dart

EM RFID Tags

Supported Devices - Dart2, G62, G120

Our RFID reader simply plugs directly into the G120 or Dart2 harness, and reads EM4001 125kHz tags (available from DM or 3rd party suppliers). The G62 can be made to read RFID tags (including DM tags) via the use of a 125kHz card reader which outputs 1-wire.

Example:

It should be noted that both the EM variant of tags and HID tags use 125kHz - make sure you don't mix up between types.

HID Cards

Supported Devices - Dart2, G62, G120

HID Global is a manufacturer of security and access control products. Their cards and readers are commonly used in buildings and worksites. To read these cards with our devices, a suitable reader must be sourced. One which outputs Wiegand can be used with the G120, or one which outputs 1-wire can be used for the Dart2, G62 or G120.

Examples:

MiFare Cards

Supported Devices - Dart2, G62, G120
