What is RFID and How Does it Work with Multiple Tags?

تقنية تحديد الهوية بموجات الراديو, or تحديد الترددات الراديوية, is a لاسلكي التكنولوجيا التي تستخدم الموجات الراديوية to identify and track tags attached to objects. An تقنية تحديد الهوية بموجات الراديو system consists of two main components: علامات RFID و قارئات RFID. علامات RFID contain a microchip that stores information and an هوائي that allows the العلامة ل receive signals from and نقل data to an قارئ RFID. قارئات RFID are devices that emit radio waves and receive the إشارة back from the العلامات. This capability allows readers to identify large groups of items at once.

One of the key advantages of تقنية تحديد الهوية بموجات الراديو over traditional methods like الباركود is its ability to قراءة علامات متعددة simultaneously. When multiple العلامات are within the قراءة المدى من قارئ RFID, the reader sends out a إشارة that energizes all the العلامات at once. The العلامات then respond with their unique identification information. The reader’s ability to process these multiple responses makes تقنية تحديد الهوية بموجات الراديو efficient for tracking inventory, managing assets, and streamlining various processes.
