NFC coils work by allowing a device (usually a phone) to collect data from another device or an NFC tag within a limited range. In a way, this technology is similar to contactless payment cards integrated inside the phone. Quite similar. NFC technology does not need to set up 2 connected devices at the same time, and only requires a simple device contact to establish a wireless connection.
NFC coilInformation is also transmitted through electromagnetic induction coupling in the radio frequency part of the spectrum, but there is still a big difference between the two. First of all, NFC is a wireless connection technology that can provide easy, secure and fast communication. Its transmission range is longer than RFID is small, and the transmission range of RFID can reach several meters or even tens of meters. However, because NFC adopts a unique signal attenuation technology, compared with RFID, NFC coil has the characteristics of short distance, high bandwidth and low energy consumption. Secondly, NFC Compatible with existing contactless smart card technology, it has now become an official standard supported by more and more major manufacturers. NFC coil is also a short-range connection protocol, providing easy, safe, fast, automatic communication between various devices Communication. Compared with other connection methods in the wireless world, NFC is a close-range private communication method. Finally, RFID is more used in production, logistics, tracking and asset management, while NFC is used in access control, public transportation and mobile payments, etc. field plays a huge role.
NFC coils support a variety of applications, including mobile payments and transactions, peer-to-peer communications, and information access on the move. With NFC phones, people can connect their desired entertainment services and transactions anywhere, anytime, and on any device, thereby Complete payment and get poster information. NFC coil can be used as contactless smart card, smart card reader terminal and data transmission link between devices. Its application can be divided into 4 basic types: payment and ticket purchase, electronic passenger ticket , intelligent media and data exchange and transmission.
NFC coil has the characteristics of low cost, convenient use and more intuitive, which makes it more potential in some fields - NFC coil can realize communication within the range of various devices through a combination of chips, antennas and some software.
