RFID on metal (abbreviated to ROM) are radio-frequency identification (RFID) tags which perform a specific function when attached to metal objects. The ROM tags overcome some of the problems traditional RFID tags suffer when near metal, such as detuning and reflecting of the RFID signal, which can cause poor tag read range, phantom reads, or no read signal at all. The RFID-on-metal tags are designed to compensate for the effects of metal. There are several tag design methods to create ROM tags. The original method was to provide a spacer to shield the tag antenna from the metal, creating bigger tags. New techniques focus on specialized antenna design that utilizes the metal interference and signal reflection for longer read range than similar sized tags attached to non-metal objects.〔Drew Nathanson, Tom Wimmer, 2009 RFID transponders, Inlays, IC s, ITU-T Lighthouse Technical Paper. May 2009. http://www.vdcresearch.com/_Documents/executivebrief/wp-attachment-2526.pdf.〕 RFID-on-metal transponders will continue to create new opportunities for users in a wide range of asset tracking and broader industrial applications. The main applications are asset tracking on servers and laptops in IT data centers, industrial manufacturing quality control and manufacturing, oil and gas pipeline maintenance, and gas cylinders.〔How RFID can read in metal XERAFY. http://www.xerafy.com/main/sites/default/files/Can_RFID_Tags_Work_inside_Metalv2_Talton.pdf, 2010〕 The technology is evolving to allow transponders to be embedded in metal. The capability allows manufacturers to track small metal items from cradle to grave. The main focus for RFID inside metal is tool tracking, weapon tracking, and medical device quality control. ==See also== * International Organization for Standardization * Electronic Product Code 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「RFID on metal」の詳細全文を読む スポンサード リンク
