Understanding RFID Printing Technology
(RFID) Radio frequency identification is one of the most impressive and useful labelling and item tracking technologies to come along in some time, more and more companies that supply both industry and government are being required to use RFID technology to identify their items during transportation and storage.
RFID is an automatic identification tech whereby digital data encoded in a RFID tag or label is captured by a reader using radio waves. Simply put, RFID is similar to bar code scanner tech but uses radio waves to capture data from tags or labels, rather than optically scanning the bar codes on a label. RFID does not require the tags or labels to be seen to read its stored data and information.
The completed label consists of a unique layer, called the inlay, inserted into a traditional label construction. The inlay contains an antenna and microchip that stores data or information. The (RFID) Radio Frequency Identification label communicates via radio frequency or radio waves rather than optical scanning, and is produced using a type of thermal transfer digital printing tech.
The Difference between Passive and Active Tags
(RFID) Radio Frequency Identification tags come in various formats and the most commonly known and cheapest to produce, are passive RFID tags. They work on the radio signal or waves of the scanner to power the circuit and antenna, and produce a relatively weak signal or wave that scanners can only detect within a relatively close proximity. Battery assisted tags use an internal power source to boost the signal, allowing scanners to pick them up from a further distance. Active (RFID) Radio Frequency Identification tags contain an internal power source strong enough to transmit data or information through the antenna in regular pulses, and work best in situations where constant monitoring of the tag is necessary.
The tech required for printing (RFID) Radio Frequency Identification tags is continuously growing but a good deal of research still remains unresolved and material prices need to drop before printed tags can be offered commercially and before they can be printed directly onto the packaging items. However, once these two tasks are achieved at an affordable price some believe that (RFID) Radio Frequency Identification tagging will someday become pervasive throughout supply chains for almost every type of good.
