Oppo unveiled a prototype NFC Zero-Power Tag MWC that does not require a battery.
The Zero-Power Tag draws energy to operate from RF signals emitted by radios, TV towers, cell phone stations, and Wi-Fi hotspots.
The post-energy device can modify the surrounding radio signals and transmit them back.
Thus, in the future, users will not be able to monitor the battery charge in the NFC tag, the device will always be ready for use and will not let you down at the right time.
The Oppo prototype is shaped like a plastic fiber, similar to a bank card. But in the future, the NFC tag will be sold as stickers that you can stick anywhere. [Phone Arena]
