摘要： Disclosed is an RFID interrogator having a collision type identification function and a control method thereof. It verifies whether or not a collision occurs in a received signal by analyzing data of a signal received from an RF communication unit and performs a corresponding collision resolution operation by diagnosing a collision type in accordance with a collision generation means between the corresponding RFID interrogator and other interrogators or a tag. Since all types of collisions that occur between the RFID interrogator and the tag can be identified, a reason for occurrence of the collisions can be rapidly recognized to cope with the reason for the collisions.

摘要： Provided is a communication method for radio frequency identification (RFID). In order to transmit a command message with respect to an RFID tag, an RFID reader generates a command message comprising a command code indicating a type of command to be delivered to the RFID tag, a response format having one or more bits for indicating a type of additional data to be added to a response message to be received from the RFID tag, and an identifier identifying the RFID tag; and transmits the command message to the RFID tag, thereby allowing the RFID tag to immediately transmit the additional data via the response message in response to the command message.
