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.

Passive tag including volatile memory

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.

Apparatus for storing sensing data in tag and method thereof

Provided are a radio frequency identification (RFID) tag and a wake-up method thereof. The RFID tag includes: a power source that supplies a driving voltage; a continuous wave detector that receives the driving voltage from the power supply so as to detect a continuous wave in a signal received from an RFID tag reader; a command detector that selectively receives the driving voltage and detects a command in the signal; and a controller that executes the command detected by the command detector by supplying the driving voltage to the command detector if the continuous wave is detected, and stops the driving voltage from being supplied to the command detector if no command is received from the command detector for a predetermined time period.

Lower power battery-assisted RFID tag having improved recognition distance, and wake-up method thereof
