Sometimes we can always hear what is applied to RFID technology, but do we really know what RFID technology is? It is understood that RFID technology, also known as radio frequency identification technology, is a non-contact automatic identification technology, which can automatically identify the target object through radio frequency wireless signals, and also collect relevant data information. It is now one of the very common wireless communication technologies in the meeting. In our daily life, the use of RFID technology is reflected in all aspects of our life, such as travel, medical treatment, food, transportation, etc. Then, in daily life, where is RFID technology applied? Let me tell you about it!
First of all, let's talk about the most common thing that everyone has, that is, ID card. The second-generation ID card we are dealing with now is applied to RFID technology. RFID chip is embedded in the ID card, in which our personal identity information is entered. When the ID card is close to the sensing range of the reader, the RFID chip will electronically sense the RF signal sent by the reader, and then the data information in the RFID chip will be read by the reader, and then the reader will transmit the read data information to the background data processing center for decoding, so as to obtain the required relevant information.
In addition, one thing we use in communities, companies, schools and other places - access cards, which also have RFID chips embedded in them. Personal information is also entered into them through RFID readers. When the door card is close to the sensor, the sensor can transmit the information entered by the RFID chip of the door card to the background system for matching. After the matching is successful, the door will be opened.
Even communities with underground garages can use RFID technology to achieve parking free access. Attach RFID parking tag card to each car. When the car enters and exits the underground garage, the RFID reader will directly recognize the corresponding tag information. After confirming that the information is correct, the vehicle can be released directly. There is no need to stop and swipe the RFID cards to enter and exit the garage, which can effectively improve the low traffic rate caused by swiping the card in and out of the traditional parking lot.
The above are all small scenarios that apply RFID technology in daily life. In addition to these application scenarios, RFID technology can also be applied to food traceability, air baggage consignment, production automation, electronic tickets, industrial warehouse management, animal breeding and other industries. Therefore, RFID technology is widely used in our daily life.
