'''Singulation''' is a method by which an [[RFID]] reader identifies a tag with a specific [[serial number]] from a number of tags in its field. This is necessary because if multiple tags respond simultaneously to a query, they will [[Radio jamming|jam]] each other. In a typical commercial application, such as scanning a bag of groceries, potentially hundreds of tags might be within range of the reader.

then the tag reader can read data from each and every tag without interference from the other tags.
