BTLECurrent LectureRFID - Radio Frequency Identification - transmits the identity of an object/person using radio waves, the tag is being read by a reading device within proximity o 10 years old technology o ex. EZ-Pass, public parking garage keys, passports, etc. - transponders/RFID tags - the microchip is about half than a mm, can be mounted on many types of materials - this is an automatic identification technology (like barcodes, optical character reading, etc.) - people can be tracked with the RFID and this can be a security issue - they have created metal cases to block this because metal kills the signal - more efficient and smarter than a barcode - readers are built with an antenna for communicating radio signals with the tags, can have multiple antennas to send/receive signals - RFID is the future of retail (inventory, check out, etc.) - professional sports teams use a pill to monitor the body temperature of athletes and tracking athlete playing statistics using RFID technology Types of Tags - passive tag - most commonly used, activates itself and transmits data using power generated by radio waves, low cost tags, no battery, you must be within a 3m diameter - active tag - can detect up to 100m, battery powered, more expensive - tags can be as cheap as $0.05 BTLE These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- BTLE (Bluetooth Low Energy) - a constant low power connection, awakens when someone requests/detects it, about a year old o ex. your phone is always connected to satellites o ex. iBeacon - company application is able to notify you when they detect you are in proximity to their "beacon", etc. o ex. Tile technology - a form of RFID that works on radio frequency, Bluetooth must be turned
