NFC technology in PPE: how it works
At the heart of the Exteryo Safety 4.0 system is NFC (Near Field Communication) technology, which makes it possible to turn any piece of personal protective equipment into digital PPE. Let's take a closer look at how these small but powerful components work.
Anatomy of an NFC tag
NFC tags are miniaturized electronic circuits operating at the standardized frequency of 13.56 MHz. Their structure is surprisingly simple yet effective:
Antenna: a conductive circuit that receives and transmits signals Chip (die): the brain of the tag, soldered to the end of the antenna Dual memory: Non-modifiable flash memory: contains the unique, permanent UID (Unique ID) code Rewritable EEPROM memory: can hold custom, updatable data It is precisely this combination of elements that makes NFC tags perfect for PPE traceability.
Passive by nature: zero consumption, zero emissions
A fundamental characteristic of NFC tags is their passive nature. This means that:
They require no batteries or power of their own They activate only when brought close to a reader (smartphone) They emit no radiation when not in use The reader supplies the necessary energy through electromagnetic induction This characteristic makes them ideal for application on PPE: they do not interfere with protective functions, they need no maintenance and they last practically forever.
Advanced NFC tags for every application
Exteryo has gone beyond the limits of traditional NFC stickers, developing and patenting innovative solutions specific to different types of PPE:
Impact-resistant tags for helmets and fall-arrest equipment Flexible tags for clothing and fabrics Specific tags for metal surfaces, which would normally interfere with the signal Solutions for extreme environments (high temperatures, humidity, chemical agents) This variety makes it possible to digitalize practically any type of protective equipment, from safety footwear to the most complex fall-arrest systems.
Unique identification and integration with Exteryo Safety 4.0
The Exteryo Safety 4.0 system uses the UID (Unique ID) code held in the tag's non-modifiable memory. This code is absolutely unique and cannot be altered, guaranteeing:
Certain, unambiguous identification of every single piece of PPE Impossibility of cloning or duplication Complete traceability throughout the device's life cycle When the Exteryo Safety 4.0 app reads a tag, it automatically identifies the device, instantly showing:
The complete PPE sheet The inspection history The technical information Expiry dates and compliance status The result is an optimized inspection process that cuts times by 40% and errors by 50%
Safety connection is a Safety Revolution
