Sharp develop transparent NFC antenna display

Sharp Japan have developed a transparent NFC antenna that can be right built into the device's display. This enables payment and authentication by simply holding an NFC-compatible smartphone or IC-card over the dispay interface.

Because the NFC antenna is transparent, it can be integrated into the display transforming the entire display's surface into an active region. The antenna's invisible wires and metal mesh can cover areas of up to 42 inches. Although Sharp do not expect the transparent antenna to be used in small displays, it is also possible to install it into a smartphone's display. This has also led to an increase in the communication distance – from 2.5 cm to 3.0 and even 3.5 cm – with response times of less than 1 second.

Applications of this transparent NFC antenna include billing at POS terminals and vending machines, individual authentication in business, educational, medical, amusement, etc. facilities.

Sharp Japan are planning to begin mass production of the transparent NFC antenna in the 2019 fiscal year.
