How does a RFID reader acquire information from the tags?
RFID methods utilize radio waves to accomplish this. RFID tags contain an integrated circuit and an antenna, which are used to transmit data to the RFID reader (also called an interrogator). The reader then converts the radio waves to a more usable form of data.
How do RFID labels work?
Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader.
How can RFID tag be activated?
The RFID reader is a network-connected device that can be portable or permanently attached. It uses radio waves to transmit signals that activate the tag. Once activated, the tag sends a wave back to the antenna, where it is translated into data. The transponder is in the RFID tag itself.
What kind of information is stored in RFID tag?
Tag: A radio antenna attached to a microchip which stores a number that can uniquely identify an object. from proximate RFID tags.
How do you collect RFID data?
To collect data using RFID technology, operators are not as limited — they simply need to be within the range of the tag. This means that employees can collect data for any item within the read range without physically moving from shelf to shelf. This also means that more than one item can be read at once.
How are passive RFID tags powered?
Passive RFID tags don’t have an internal power source. They utilize the electromagnetic waves received from a reader. Once a reader transmits to the tag, an antenna inside the device creates a magnetic field. The tag circuit uses the power generated to transmit data back to the reader.
What are RFID tags typically used for?
RFID tags are a type of tracking system that uses radio frequency to search, identify, track, and communicate with items and people. Essentially, RFID tags are smart labels that can store a range of information from serial numbers, to a short description, and even pages of data.
