Re: Improving RFID reader throughput!

Folks,

I'm doing performance measurements on our MCU based RFID
reader. The very problem I'm facing is redundancy of tag ID (say 12
bytes) transmission, every time my MCU receives a tag ID; will just
push that ID to UART without any prior knowledge of that it is sending
the same ID again and again. (Due to poor designs of RFID tag protocols
single tag can response its ID repeatedly unless some other tag steps
in). Is it possible to implement some AI or data structure technique to
avoid that? And to decide that this tag id was pushed before so no use
to resend go-on to process another incoming IDs.

I just can't ignore the incoming tags while executing some complex
comparison or say search algorithm even assuming that I have 2K free
memory.


Thanks for your time

What tag formats are you trying to read? If it is one or more of
the EPC Global formats, all of them (Class 0, Class 1, and Class 1 Gen
2) have a means within the protocol to silence a tag once it has
reported its ID. If it is some other tag protocol, I'm afraid I
cannot help you.
