    Configure the read speed of RFID reader?

    Hi all,

    I wonder if the read speed of RFID readers is adjustable? More specifically, for RFID reader and tags with EPC Gen 2 protocol, the reader is supposed to read one tag at a time based on TDMA mechanism to avoid collision. In this case, can I configure the reader/tag so that the reader's speed can be set to e.g. read one tag every 1 ms? What is this spec called? I read some data sheet of RFID readers but they don't discuss such a thing.

    Thank you very much in advance!

    i dont know answer of your question .
    i also need help . just i want to acknowledge RFID reader for connections.
    i mean i want to send command to rfid to check if it is connected with my controller.

    I worked on NFC which works on IEC 14443 protocol and uses 13.56MHz.

    Hardware used was MSP430 and used TRF7970 as RF chips. I could program that it can read upto 16 tags . But we can still program and set it according to our requirements.

    Datasheet for the chip you are using as RF communication should help..

    Re: Configure the read speed of RFID reader?

    Maximum read speed is restricted by the EPC Gen 2 protocol which you may want to study. From my limited knowledge of EPC, 1 ms seems unrealistic at first sight, at least several ms are needed I believe.

    Nevertheless I see several readers that have a programmable read rate respectively a read trigger input.

    I believe any reader will have some status, hardware version or similar read commands that will clearly show the connection status. Obviously you have to refer to your specfic reader documentation.
