摘要:
A passive tag including a volatile memory is provided. The passive tag includes: a sensing unit which senses or measures information about environmental surroundings of the tag; a volatile memory; a non-volatile memory; and a control unit which firstly stores resultant data sensed or measured by the sensing unit in the volatile memory and then moves the data stored in the volatile memory to the non-volatile memory according to pre-set conditions. Therefore, the life of the tag is prolonged and stability of important data can be secured.
摘要:
An apparatus for storing sensing data in a tag and a method thereof are provided. According to the present invention, data measured by the sensor is stored in volatile memory and important data from among the data stored in the volatile memory is stored in non-volatile memory according to a pre-set data loss prevention mechanism so that a battery and the tag including the battery have a longer life and stability of data can be secured.

摘要:
An apparatus and method for detecting a wake-up burst of an active RFID tag are provided. The apparatus and method, for detecting the wake-up burst of the active RFID tag, are capable of reducing power consumption of the RFID tag by enabling the RFID tag when a RFID reader starts to communicate.
摘要:
An apparatus and method for managing power of a radio frequency identification (RFID) tag are provided. It is possible for the apparatus for managing the power of the RFID tag to effectively reduce power consumption of the RFID tag by measuring the power strength of a radio frequency (RF) signal received from an RFID reader and adjusting a level of transmission power based on the measured power strength of the signal.
摘要:
A time division multiple access (TDMA) control method used by a mobile radio frequency identifier (RFID) reader through a mobile phone base station and a mobile RFID reader are provided. Each mobile RFID reader occupies a frequency channel during a time slot allocated through a mobile communication base station, thereby avoiding interference between readers.
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.
摘要:
The present invention relates to a mobile radio frequency identification (RFID) reader and a RFID communication method using a shared system clock. According to the present invention, clock for synchronizing the mobile RFID readers can be shared without changing hardware of a conventional RHD device. Also, since the shared clock is used, a technology for preventing a collision with the readers can be easily realized in a mobile multi-reader environment.
摘要:
Disclosed are a radio frequency identification (RFID) tag capable of supplying an Internet service quickly and conveniently, an operation method thereof, and a system and method for controlling network access based on a mobile RFID. Network access data is generated by communication between an RFID terminal and an RFID tag. The mobile RFID terminal connects with a network gateway by reading the network access data, thereby supplying the Internet service quickly and conveniently.
