תיוג RFID הוא מערכת זיהוי המשתמשת בהתקני זיהוי של תדרי רדיו קטנים למטרות זיהוי ומעקב. מערכת תיוג RFID כוללת את התג עצמו, התקן קריאה/כתיבה, ויישום מערכת מארח עבור איסוף נתונים, עיבוד, ושידור. An RFID tag (מכונה לעתים משדר RFID ) מורכב משבב , some memory and an antenna .
RFID tags that contain their own power source are known as active tags. Those without a power source are known as passive tags. A passive tag is briefly activated by the radio frequency ( RF ) scan of the reader. The electrical current is small — generally just enough for transmission of an ID number. Active tags have more memory and can be read at greater ranges.
Increasingly, RFID tagging is used in supply chain management as an alternative to bar code technology. Although more expensive to use than the bar code stickers, RFID tags don’t get dirty or fall off or require an unobstructed line-of-sight between the tag and the reader.
There are almost endless possible uses for RFID tagging. Injectable ID chips have been used to track wildlife and livestock for over a decade. An injectable RFID tag called the VeriChip can be used to help medical personnel identify a patient who is unable to speak — and even provide access to the person’s medical records.
RFID tagging is somewhat controversial because the tags could theoretically be cloned or used for illicit tracking.
