Inspection (Tests)

Your articles which are equipped with CRYPTALLOY RFID shielding foil offer your customers maximal RFID shielding and thus protection of their privacy.

tuev_zertifikatCRYPTALLOY has been tested by SGS/TUV Saarland Forster GmbH for RF attenuation capabilities and verified qualification for shielding of RFID/HFC tags against unauthorized access in commercial frequency bands of 125 kHz, 13.56 MHz and 900 MHzaccording MILSTD-285 / NSA65-6 / IEEE299 / EN50147-1 .

To provide security, correct application and a final functional check are necessary.


  • the CRYPTALLOY material is constantly tested in the laboratories of Kryptronic Technologies
  • the products of its customers undergo extensive tests.

Manufacturers and Kryptronic Technologies are interested in optimizing the products’ RFID shielding properties;

  • In close cooperation with its manufacturers, Kryptronic Technologies supports the correct processing of the RFID shielding material CRYPTALLOY already during the development phase (quick analysis).mounting instructions
    This also includes a sampling inspection on request..
  • before the start of production:
    Before serial production starts, consumer products once more undergo an internal test procedure and, if the results are positive, are certified by Kryptronic Technologies (initial inspection).

    Test Laboratory
  • during serial production (random inspections):
    Random in-process inspections from current production (follow-up inspection).


The general shielding of electromagnetic radio signals is tested in the most frequent RFID frequencies with the aid of appropriate measurement equipment:

  • 125 kHz
  • 13,56 MHz
  • 433 MHz
  • 868 MHz

In order to verify results, a test for practicability is performed with various RFID readers and writers under real-life conditions. For the test, standard RFID cards in ISO size are used. The test results are scientifically reproducible.
