Radio Frequency Identification (RFID, electronic tag) and Near Field Communication (NFC) are two popular keywords, and both belong to tagging technology (Tagging). NFC is developed on the basis of RFID. NFC is essentially no different from RFID. They are both used for signal transmission between two objects that are geographically close.Today qihe smt pick and place machine sharing what is the difference between RFID and NFC technology?<\/p>\n\n\n\n

From a professional perspective, RFID is a non-contact identification technology, divided into two types: active and passive. Working principle: The RFID reader emits radio frequency, which passes through the coil of the electronic tag to generate a signal. The reader reads the information and decodes it to complete the entire identification process. In general, active tags (active tags) can also actively send out signals. The RFID system is mainly composed of two types: reader (Reader) and transponder (Transponder). <\/p>\n\n\n\n

RFID tags can generally be scanned at distances of up to 100 meters and do not require a direct line of sight to the reader. NFC generally requires a direct line of site to the reader, and also requires the communicating devices to be within a few centimeters of each other.<\/p>\n\n\n\n

NFC is a technology currently widely used on mobile phones. Working principle: When two NFC devices approach each other within a relatively short distance, they exchange information with each other and complete corresponding transactions and other functions. The biggest feature of NFC is that the reader and transponder are integrated into the same chip. The biggest highlight of NFC technology is the addition of point-to-point communication function, which can quickly establish P2P (point-to-point) wireless communication between Bluetooth devices. NFC devices find each other and establish communication connections. The two devices in P2P communication have a peer-to-peer relationship, while the two devices in RFID communication have a master-slave relationship.<\/p>\n\n\n\n

The relationship between the two: From a mathematical perspective, NFC can be considered to be a subset of RFID, that is, RFID with a communication distance within 10cm or 4 inches is NFC. This difference is mainly due to the fact that in some applications specifically designed for cash payment and credit cards, other devices can also receive personal RFID information under the communication distance of RFID, so there are many unsafe factors; and for NFC work, it is effective The distance is about 10cm, so it has high security itself. If you use some special signal collection equipment, you can read RFID information from a considerable distance.<\/p>\n\n\n\u9605\u8bfb\u66f4\u591a\uff1aWhat is the difference between RFID and NFC technology?<\/span><\/a>\n\n\n
