Web NFC provides sites the ability to read and write to NFC tags when they are in close proximity to the user's device (usually 5-10 cm, 2-4 inches). NFC stands for Near Field Communications, a short-range wireless technology operating at 13.56 MHz that enables communication between devices at a distance less than 10 cm and a transmission rate of up to 424 kbit/s.

The LPC11U24 is an ARM Cortex-M0 based, 32-bit microcontroller, with a USB 2.0 full-speed device controller. PN7150 embeds a new generation RF contactless front-end supporting various transmission modes according to NFCIP-1 and NFCIP-2, ISO/IEC14443, ISO/IEC 15693, MIFARE and FeliCa specifications. Optimized for fast design-in, NXP’s PN7150 high-performance NFC controller is fully compliant with the NFC Forum. Peer-to-peer mode establishes a two-way communication channel between a pair of NFC-enabled devices. When a user brings two devices close to each other, the two NFC chips establish a P2P connection and exchange data. Peer-to-peer - for more complex interactions In this mode, it is USB NFC Dongle that generates the RF field, while a tag or card only modulates it.ģ. It can both read or write to a tag (although reading is a more common use-case because tags will often be write protected). Here, NFC USB Dongle communicates with a passive tag, smart card, or an NFC device operating in card emulation mode. Read/Write - where NFC USB Dongle behaves as an NFC Reader/Writer Card emulation mode, however, is not useful just for smartphones, but for any type of portable device.Ģ. A typical application of the card emulation mode is how people use NFC in their smartphones to replace several cards, badges and tags at once (using the same phone for tollgate check-ins, contactless payments and so on). It doesn’t initiate the communication, it only responds to an NFC reader. In this mode, NFC USB Dongle emulates an NFC tag. Card emulation mode - where USB NFC Dongle behaves like a smart card or a tag NFC frontends can operate in three distinct modes:ġ. Communication between two devices is established in the simplest way possible - by bringing them close to each other. NFC is designed to be intuitive for users. The USB interface is provided by NXP’s LPC11U24 MCU, and the NFC functionality is ensured thanks to PN7150. NFC USB Dongle features an LPC11U24 MCU which works in conjunction with the PN7150. NFC USB Dongle can be set to behave either as an NFC reader, or a tag, or to establish a two-way connection with another NFC device. It allows interacting with all NFC devices on the market according to NFC Forum: from simple NFC tags to NFC-enabled smartphone. This NFC controller supports all NFC Forum communication modes like peer to peer, reader/writer and Host Card Emulation. The USB NFC Dongle is powered through USB connector. NFC USB Dongle is an NFC Reader-Writer based on NXP’s PN7150 high-performance full NFC controller, supporting all NFC Forum modes.
