METHODS AND APPARATUSES TO IDENTIFY DEVICES
First Claim
1. A method performed by a reader, said method comprising:
- transmitting, in one command, a portion of an identification code, the portion comprising a plurality of bits but not the entire identification code; and
receiving a response from a tag, which has a match to said portion, wherein the response indicates at least one next bit in said tag'"'"'s identification code and excludes the portion.

Abstract
Methods and apparatuses for identifying devices, such as RF tags, are described. In one exemplary method of an embodiment of the invention, a reader identifies tags without requiring or determining whether a response to an interrogation was a single response from a single tag or multiple responses from multiple tags. In another exemplary method of an embodiment, a method is performed by a tag in an identification system, and the method includes receiving a first data from a reader, and correlating the first data with a first corresponding portion of the tag'"'"'s identification code, and specifying a match if the first data matches the first corresponding portion, and receiving second data which, combined with the first data, is correlated with a second corresponding portion of the tag'"'"'s identification code.
