Datafox reading methods for access control
Our devices for electronic access control support different reading methods (type of data acquisition). Basically, four reading methods are distinguished:
- RFID transponder (RFID chip) reading methods
- Biometric reading methods (fingerprint)
- Magnetic card reading method
In addition to the RFID reader, magnetic card reader or fingerprint scanner, Datafox access control devices also have a keypad to enter a PIN code, which then opens the door or sets the machine in operation.
Access control with RFID reading
Datafox access control devices work with RFID technology (Radio Frequency Identification), among others.
In access control devices with RFID reading method, an RFID chip in the form of a card or key fob is held contactlessly against the access control (ACC) reader. If access authorization is detected, the electric door opener is activated.
A distinction is made between pure access control readers, which pass on information to a PC or a Datafox access master for further processing, and complex devices such as access terminals, equipped with several functions such as personnel time recording and production data acquisition. These devices usually have several integrated readers (RFID, magnetic card and biometrics).
Advantages of access control with RFID transponders
- Secure access authorization by RFID chip
- Lost chips can be blocked within seconds using a delete card
- Low follow-up costs in case of chip loss - only the lost chip has to be has to be replaced.
- Easy installation & use
- Robust, weatherproof technology suitable for outdoor and indoor use
- Can be networked as access control systems for multiple locations
Access control with fingerprint
Datafox offers numerous devices with fingerprint access control. These are devices with multi-reading methods, which in addition to the fingerprint reader also have an RFID transponder reader integrated and have a USB port or RS232 port for an external magnetic card reader.
Access control with the help of biometric data (fingerprint) is mainly used in highly sensitive areas such as government buildings or high security areas (prisons, laboratories, research facilities, etc.). However, biometric access control can also be used in other situations such as leisure facilities - to speed up admission control and to prevent unauthorized use of season tickets, for example.
Access control with magnetic cards
Magnetic cards are still very popular as a means of identification for access control, e.g. in hotels. The magnetic stripe card is simply pulled through the card reader at the door. The sensor in the card reader sends the data to the control center and, if authorized, the door opener is activated.
