    摘要： A bi-slot tree based tag identification method in RFID systems includes (a) transmitting an inquiry of (n-1) bits to each tag at the reader; (b) deciding whether the inquiry of (n-1) bits are identical with first (n-1) bits of each tag ID when receiving the inquiry of (n-1) bits at each tag within a readable range of the reader; (c) transmitting each tag ID by one bit from (n+1) th bit to last bit thereof to the reader through different time slots based on n th bit value of each tag ID at the tags whose first (n-1) bits are identical with the inquiry of (n-1) bits; and (d) at the reader, checking whether there is a collision among the tag IDs received from the tags and identifying each tag ID of the tags based on the check result.
