The common RFID card in life!

Talking about RFID, many people can't understand what exactly this is, more professional detailed introduction is this way. RFID card chip (radio frequency identification technology system) is a non-contact automatic retrieval system, it automatically retrieves the target object through the frequency radio network signal, and obtains statistical data, composed of rfid tags, card writers and the Internet.

Is particularly obscure and difficult to understand, special high-end atmosphere, repeatedly read several times are not clear what this is exactly. In fact, this kind of technical daily life is very common, diagnosis and treatment, food category, traffic and travel these, all have his shadow.

First of all, the moment every person croaks, one of the larger things is to his record household registration, grow up indispensable to do ID cards. Why their ID cards can be sensed, because the ID card is embedded in the cell phone RFID card chip, ID card into the reader's induction area, the chip and the reader to send out radio frequency signals to carry out electronic device induction, the chip caused by a short power supply system, and then the chip in the information transmitted to the reader, the reader will get the information sent to the Data processing center to carry out coding and decoding.

Next, most people will use the access card, there are school cards, residential community cards, company cards, in fact, each access card also used on the RFID, which has personal information. When the access card touches the sensor, the sensor will pass the information of the access card to the system to carry out the pairing, when the information is sensed, it will open the door.

If you drive out from the parking space every time, have you ever thought about how the system is detected, how to charge? This is actually the development of cpu RFID card technology. According to the loading of information on the RFID logo, the use of radio frequency identification technology to load the logo information in the case of no contact, and then fully automatic repair of the information.
