Mechanical Vehicle Rfid Tag Anti - Variant/High Temperature Rfid Tags With 8kb
Mechanical packaging standard ibutton key fob for access or start the vehicle
The iButton is a mechanical packaging standard that places a 1-Wire component inside a small stainless steel "button" similar to a disk-shaped watch battery. iButtons are connected to 1-Wire bus systems by means of sockets with contacts which touch the "lid" and "base" of the canister. Each vehicle driver will be equipped with a key in order to access or start the vehicle/truck. Once the key presented to its receiver, the vehicle will start and driver name and access time will be recorded in the tracking software.

Unique 64-bit registration Number;
Built-In Multidrop Controller for 1-Wire Net;
Digital identification by momentary Contact
which approved to be reliable performance than others,
CMOS microcircuit is essentially an electronic carrier of the unique 64-bit digital code.
The code is stored in the internal nonvolatile memory.
The data exchange is performed by the protocol 1-Wire,
which requires one sole data pin and the common pin.
The microcircuit supports the function of the protocol 1-Wire of ROM search,
which makes it possible for several devices to operate on one bus.
This protocol determines the alteration conditions of the bus status
and the time intervals during synchronization by the synchropulses cuts of the control device.
Data readout and writing are performed by the junior significant bit forward.
