Seals for Taximeters – What They Are and What They Are For

In public taxi transport service, the taximeter is an essential element that ensures the correct calculation of the service price provided to the user based on the rates approved by the competent authority.
The taximeter, as a metrological device, under current regulations, must have strict security measures that guarantee the metrological control of the instrument. Among these measures, it requires physical seals—both from the manufacturer and the installer or a verification center—that certify the equipment has been handled and verified by an authorized entity.
What are security seals?
Security seals are physical components, generally made of plastic, that are placed on the access ports of the taximeter, which are used for its programming. Their purpose is to show that the taximeter has been programmed, calibrated, or verified by an authorized entity.
Each seal has a unique code or serial number that identifies the authorized entity that handled it, allowing for detailed tracking of the taximeter. In many countries, the mandatory use of these seals is regulated, and unauthorized tampering may result in fines, vehicle disqualification, or even suspension of the license.

What are the seals for?
Seals serve multiple essential purposes:
• To ensure that the taximeter has been handled and verified by an authorized entity.
• To facilitate authority inspections. Transport authorities can conduct faster and more effective inspections by verifying that the seals are intact.
Thus, seals are a simple but fundamental element in ensuring transparency, legality, and trust in taxi service. They are part of the commitment of all sector actors to integrity, transparency, professionalism, and respect for users.
