How to make the identification of the arrival of the car at the facility?

Question

Arduino

Hello
There is a car that workers drive and serve the facilities.
Technical vehicles that serve the facility, they stop in front of it at a distance of 20m for safety reasons.
Next, the auto operator in the tablet fills in the data of the object, performs its maintenance and completes the work.
At the time of servicing, the tablet receives data from the car via Bluetooth about the operation of the equipment installed on the car and then transfers this data to the server for processing.
In order for the service personnel not to deceive, it is necessary that the data about the object be loaded automatically.
I see the output of installing RFID tags on objects.
But here comes the problem:
1. RFID tags are difficult to fix on the object and they can be destroyed during operation
2. You need an RFID tag reader, preferably wireless, since the distance is 20m, bluetooth is no longer an option
Using GPS, it makes no sense to determine the object, since the distance between some of them is less than 50m and strong noises that the GPS may not catch in this place.
Do you have any ideas how this can be implemented?

Answer 1

20 метров для RFID технологий это очень много.
На обычных(пассивных) метках такое не сделать.

Answer 2

Answer 3

BT4 low power метки

Answer 4

Если я правильно понял задачу, то можно на объекте закрепить идентификатор например такой securityrussia.com/skud/id/85738 и считывать его с телефоном, с помощью приложения например такого spnx.ru/terminal_nfc.php
