Use cases

Our antennas can be used in a wide variety of applications, owing to their features such as small size, low-profile design, and immunity to surrounding metal.

• Smart watches

  The antenna embedded in a metal frame enables cashless payment.

• 

• Smart locks

  The antenna built into a doorknob allows smartphones or cards to be used as keys.

• 

• Wearable devices

  The antenna built into a compact wearable device, such as wireless earbuds, enables connection to the device you want to pair easily.

• 

• Displays

  Touch operation of a display is enabled by installing the antenna near or on the back of the display. This is difficult with pattern antennas.

• 

　　　　　　　

• Car doorknobs/pillars

  The antenna built into a car doorknob or pillar allows smartphones or cards to be used as car keys.

• 

　　　　　　　

• Motorcycle gauges

  The antenna built into a motorcycle gauge allows smartphones or cards to be used as motorcycle keys.

• 

Product Specifications

The antenna’s structure consists of multiple fine metal wires wound around a ferrite core.

Three modes of operation

Reader/Writer Mode	Mode that allows smartphones to be used as reading devices [Application examples] - Poster advertisements (the same use as QR codes)/Sending or extracting settings or logs from data collection devices for thermometers or pedometers/Rewriting electronic price tags - Pairing with Bluetooth devices
Card Emulation Mode	Mode that allows smartphones to be used as tags and embedded devices to be used as readers [Application examples] - Security locks (combined use of card and smartphone) - Electronic payments in stores/Membership or loyalty cards for fitness or other clubs
Peer-to-Peer Mode	Mode that allows smartphones to operate at the same level as embedded devices [Application examples] - Data exchange between smartphones - Data exchange between smartphone and PC - Sending Wi-Fi settings to embedded devices

■What does NFC mean?

NFC is an abbreviation for “Near Field Communication”. NFC is an international standard for near field communication technology that uses the 13.56 MHz frequency band. It enables communication between NFC-enabled devices when they are brought close together. NFC is enabled in many of the public transport IC cards, credit cards, smartphones, etc., and is widely used in everyday life.

■Types of NFC standards

According to the specifications, the NFC standards fall into three types: Type-A, Type-B, and Type-F. SMK’s NFC antennas support all types of NFC standards.

　　　　　　　　　　　　　　 　　　　　　　　　　　　　　 　　　　　　　　　　　　 　　　　　　　　　　　　　　 　　　　　　　　　　　　　　 　　　　　　　　　　　　　　

	Type-A	Type-B	Type-F
Features	NFC standard developed by NXP Semiconductors in the Netherlands	NFC standard developed by Motorola in the USA. Faster processing and better security are achieved with an integrated CPU.	NFC standard developed by Sony in Japan. Extremely high processing speed of approximately 0.1 sec is achieved while maintaining excellent security.
