Rfid chip with NFC portable security use technology.
All AGL reports have been loaded with anti-counterfeit rfid chips to add security to your report.
Use the NFC function of the mobile phone to directly read the chip in the report and view the authenticity of the certification anytime anywhere.
Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects.
The tags contain electronically-stored information. Passive tags collect energy from a nearby RFID reader's interrogating radio waves. Active tags have a local power source (such as a battery) and may operate hundreds of meters from the RFID reader.
Unlike a barcode, the tag need not be within the line of sight of the reader, so it may be embedded in the tracked object. RFID is one method for Automatic Identification and Data Capture (AIDC).
