2 meter range RFID reader

Projects General Guidance
1

I want to implement a security system using RFID:

  • Using a bracelet tag
  • Need up to 2-meter range

what RFID tag and reader suit for this project? any insight would be appreciated.

Currently, I'm into these:

  • 13.56MHz RFID/NFC Bracelet - 1KB
  • RFID Module - SM130 Mifare 13.56MHz
  • RFID Evaluation Shield - 13.56MHz

But I'm not sure if it will meet the range requirement.

  • Need up to 2 meter range

Tricky with a passive tag.

You maybe need a UHF tag system. These are not cheap.

hi, thank you for your quick respond.

How about 1 meter range? any cheap solution for this?

No.
With 125KHz RFID it is possible to get about 18 inch range, but that is not with the cheap hobby readers but a professional one.
