i think it's a feature on reader. you need 13,5 MHz reader for that.
and tag that can be switch off, with "anticollision" bit. (i don't remember which tag ISO)
the technic (if remember my old reading) is to read the tag on the reader, switch off the tag, read the next tag, switch off until there is no tag.
not sure but it seems you can not loop more than 10 time...
If i'm wrong, please give use the solution...
I've looked for a while and only find Skyetek M1 13.56 Mhz RFID around 100$
