Unique identification to increase patient safety

Unique Device Identification (UDI)

Unique Device Identification (UDI) is a worldwide system for the standardised identification of medical devices, which was developed in the USA. The UDI should be marked on the product in both a machine-readable format (e.g. a barcode) and in plain text. The UDI is the key to a Unique Device Identification Database (UDID), which holds a range of information on the devices.

Clear, one-to-one traceability requires specific requirements

KENUS technology meets all the requirements

Applicable in all environments


  • KENUS technology can be used anywhere.

  • RFID technology cannot be used in hybrid operating theatres because of the electromagnetic fields produced.


Visible over the entire life cycle


  • The KENUS matrix is permanently readable over the entire life cycle

  • Laser markings fade over time because of the washing processes during sterilisation





Instruments don’t get damaged over the life cycle

  • The KENUS matrix code doesn’t damage the instruments

  • Laser markings can cause instruments to corrode





Unique characteristics of the KENUS technology



Mechanically applied in a small recess:

  • Protection against mechanical damage
  • Protection against fading during cleaning or sterilisation processes
