RFID 1-Wire readers work perfectly in such cases
1. Immobilizer - prevent anyone from starting the vehicle without scanning an RFID tag first.
2. Authorized driving - keep track of who is driving your vehicle according to the RFID tag they use to authenticate themselves.
3. Auto Geofencing – gives ability to know when car leaves customized areas without RFID authorization.

Instruction:
IS630/830-1W is Suoma developed 125KHz /13.56Mhz wall-mounted card reader with one wire interface .
Protocol:

All 1-Wire devices, including iButton devices, contain an 8-byte unique registration number.
The computation begins with the MSB of the 64-bit, This 1-Wire Data consists of an 8-bit CRC, a unique 48-bit serial number and an 8- bit family code.The family code is fixed 0x01

Features:

• 125Khz frequency/13.56Mhz
• One wire communication
• Can prevent damage and wind and rain, encapsulated in a special material. May be suitable for installation in a wide variety of indoor and outdoor environments.
• Card reader accepts 9-12 DC voltage, can be used with almost all the controllers on the market.

The 1-Wire bus enumeration protocol, like other singulation protocols, is an algorithm the master uses to read the address of every device on the bus. Since the address includes the device type and a CRC, recovering the roster of addresses also produces a reliable inventory of the devices on the bus. To find the devices, the master broadcasts an enumeration command, and then an address, "listening" after each bit of an address. If a slave's address matches all the address bits sent so far, it returns a 0. The master uses this simple behavior to search systematically for valid sequences of address bits. The process is much faster than a brute force search of all possible 56-bit numbers, because as soon as an invalid bit is detected, all subsequent address bits are known to be invalid. The 56-bit address space is searched as a binary tree, allowing up to 75 devices to be found per second. The order in which device addresses are discovered by this enumeration protocol is deterministic and depends only on the device type and serial number. Bit-reversing these 56 bits yields the order of discovery for devices using Maxim's published algorithm (algorithm defined in Application Note 187[8]). The search algorithm can be implemented in an alternative form, initially searching paths with address bits equal to 1, rather than 0. In this case, inverting the 56 address bits and then reversing them yields the order of discovery.
