Unique identification of vehicles belonging to a fleet of vehicles for refueling at gas stations. Project Proposal.

Project14 | RFID or NFC Project Proposal

This is my project proposal entry for Project14 | RFID or NFC competition. More than carrying out a real project, it is the evaluation of ST tags to solve a problem that I have currently had to review using NXP tags, the unique identification of vehicles belonging to a fleet of vehicles for refueling at gas stations or recharging batteries at electric vehicle charging stations.

The problem

Both official and private vehicle fleets have to control the refueling of their vehicles. Depending on the vehicle's authentication scheme, drivers or outside personnel can trick and refuel their private vehicles with the credentials of the fleet vehicle.

The solution

A simple solution is the placement of NFC tags with tamper detection in vehicles. These tags must have an internal counter and be capable of generating a URL or/and a unique token signed by a unique key stored in the tag. To authorize refueling, a mobile reader must be approached, which can be an NFC phone or an NFC-enabled payment terminal.

The token can be verified online against a database and an HSM or offline with a SAM module. In this way, the token can only be used once. The tag cannot be removed from the vehicle without being destroyed. The tag should work on metal surfaces and have UV protection.

I have recently been evaluating NXP NTAG 424 DNA series NFC tags which are good candidates to solve this problem. I want to evaluate which ST products could be used for this solution.

It seems that the st25tv02k (with tamper) tag may be a good candidate for this type of solution

  • Product identification and protection characteristics
    • Kill mode and untraceable mode
    • Tamper detect capability
    • TruST25 digital signature
    • EAS (electronic article surveillance) capability

I still don't know if it has an internal reading counter like the ones from NXP and what is very useful for this type of application avoiding having to write something later in the tag.

  • Great project idea.  I consulted with a company building a similar product. They had a whole range of products and parts that included smart gas pumps/nozzles, smart gas filler ports, GPS tracking, etc.  They also linked through the ODB port in the vehicle to extract and log speed, distance and other parameters in and effort to not only monitor/control fueling, but also to monitor driver habits.  Good luck!

    I was not aware of the existence of standards for OBD I thought they were manufacturers' proprietary interfaces. Thanks for pointing it out. It would be very interesting to be able to obtain that data without having to connect a cable, perhaps a device that transmits this data via NFC, but it would increase costs by needing one per vehicle. Here is another opportunity to participate in this competition.

    As you very well point out, the control of the mileage between refueling is a very important aspect to take into account in this system and I had the idea of implementing the reading through computer vision, storing both the recognized numbers and the photo of the odometer for later audits. That could be done with the same smartphone/mobile POS terminal that read the NFC tag.

    There are very loose standards, with a lot of variances between vendors.  The code to read the ODB ports was often customized on a project by project basis, based on the vehicles that were in the customers fleet.
