RFID solution needed help to find kit


I am looking for suppliers of RF modules and I hope you help me with choosing the right one. Specifically, I am reaching out to ask about the RFID readers and appropriate antennas. I am working with a design that needs to follow the requirements listed below:

  1. range between tag and antenna about 10-20cm

  2. materials between tag and antenna:

~5cm wood plate,

~5-10cm polyurethane or polyester

~0-5cm air

  1. possible some metal bolts in PU/PE

  2. tag will have to be wristband

  3. the antenna max size about A5 paper sheet

To specify:
The position of tags may differ so perfect would be circularly polarized antenna. The set will possibly work off-grid so would be nice to have something requiring less power. The tag will be connecting with a very low frequency of about 1 tag per 1-2 seconds.

I was hoping to find modules in low-frequency solutions. I am aware that distance of 10-20 cm may be a hard to get with LF/HF. I am also considering short-range UHF but the price of the module needs to be considered.

I would be grateful for your advice a what module to choose.

Please let me know if there is anything else I need to clarify. I am looking forward to hearing from you.

Kind regards,

I can’t help you much but I found this nice tutorial that should get you started.
