Application Level Events

	Application Level Events Application Level Events (ALE) is a standard created by EPCglobal, an organization of industry leaders devoted to the development of standards for the Electronic Product Code (EPC) and Radio-frequency identification Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects.

	EPCglobal The Electronic Product Code (EPC) is designed as a universal identifier (using a idiosyncratic numerical code for each different commodity) that provides a unique identity for every physical object anywhere in the world, for all time. The EPC structure is defined in the EPCglobal Tag Data Standard, which is a freely available standard. The canonical representation of an EPC is a URI, namely the 'pure-identity URI' representation that is intended for use when referring to a specific physical object in communications about EPCs among information systems and business application software. The EPCglobal Tag Data Standard also defines additional representations of an EPC identifier, such as the tag-encoding URI format and a compact binary format suitable for storing an EPC identifier efficiently within RFID tags (for which the low-cost passive RFID tags typically have limited memory capacity available for the EPC/UII memory bank). The EPCglobal Tag Data Standard defines the structure of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Radio-frequency Identification Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder, a radio receiver and transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader. This number can be used to track inventory goods. Passive tags are powered by energy from the RFID reader's interrogating radio waves. Active tags are powered by a battery and thus can be read at a greater range from the RFID reader, up to hundreds of meters. Unlike a barcode, the tag does not need to be within the line of sight of the reader, so it may be embedded in the tracked object. RFID is one method of automatic identification and data capture (AIDC). RFID tags are used in many industries. For example, an RFID tag attached to an automobile during production can be used to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
