In 1935, Sir Robert Watson Watt invented radio detection and ranging (radar), which can be considered as the early origin of RFID. The current RFID technology appeared from 1940 to 1950 and was first applied in World War II. Similar technologies were used by the Allies and Germany for identifying enemy and friendly aircraft. Charles Walton designed a portable RFID transmitter in 1973, becoming the RFID holder. The high cost of early RFID greatly hindered its commercial application. With the development of technology, hardware costs decreased, and it was not until 1980 that it began to be commercialized. After many years of continuous improvement, such as research on minimizing RFID, that technology continued to be improved. Hardware further reduces kos.

1. Pasiv RFID

Pasiv RFID i no gat pawa sos, olsem wanem em i ken givim pawa?

2. Aktiv RFID

Active RFID can be said to be active RFID, which has not been popular for a long time compared to passive RFID. However, it has actually existed in our daily lives, such as the electronic toll collection system (ETC) on highways. As the name suggests, active RFID requires external power supply and actively sends signals to RFID readers. Its size is relatively large, but it also has Ol longpela transmisen distens na bikpela spit bilong transmisin, sampela bilong ol inap inap long 100 mita. Frekwensi bilong ektiv RFID i stap long bikpela mak bilong 900MHz, 2.45GHz, 5.8GHz, na ol narapela .

 

3. Semi ektiv RFID

Due to the advantages and disadvantages of both passive RFID and active RFID, passive RFID has a short recognition distance. Although active RFID has a long recognition distance, it requires an external power supply and has a large volume. Due to market demand, this semi-active RFID system has emerged, which comes with a mobile power supply and is usually in a sleep state. It does not work and does not salim ol signal.
