Optimizing the reading of your tags easily !

In order to read an RFID HF tag in the best possible conditions you will have to pay attention on 3 major components:

  • The quality of the tag you are going to buy
  • The quality of the reader that you are going to buy
  • The size and shape ratio of the antennas from these two products

Tags are designed following the process described here:

The major chip manufacturer such as NXP, Infineon etc, ensure a chip of an optimal quality.

These chips are bought by a chip embedder who is in charge of associating this chip to an antenna on a support (card, keychain, inlays, etc..).

In this process there are chips that will have a more or less good quality according to the chip embedder and his know-how.

Regarding the reader, the reading quality will vary depending on its firmware, its design quality and its modulator-demodulator.

For an optimal reading, the ratio size/shape between the reader’s antenna and the chip antenna should be perfect.

A big antenna does not equals a high reading distance, the ratio of the duet of antennas (tag, reader) should be well-proportioned.

To optimise the reading of your tag, you will need to pay attention to:

  • Have a proportioned set of reader-tag antenna
  • A chip embedded carefully
  • An authentified chip
