The fast charging speed of mobile phones, tablets and other devices has been increased to 100W to 200W, and even 300W fast charging technology is under development. The wireless fast charging speed has also reached the 50W to 100W level. NFC, which is suitable for low-power devices, will also increase its charging power to 3W this year.

NFC is also very popular on smart phones, smart wearables and other devices, and is currently mainly used in various scenarios such as electronic payment, identity authentication, ticketing, data exchange, and anti-counterfeiting.

NFC wireless fast charging is usually between 250mW and 1W, but the NFC Forum plans to increase the power to 3W this year. The speed increase means that NFC wireless charging can support more scenarios and drive devices with larger capacity batteries.

Compared with Qi, another wireless charging standard, the advantage of NFC wireless charging is that it occupies a small area, can be charged in less than 1c㎡, and does not require a charging coil. Qi wireless charging often requires more than 10c㎡ of space.

Of course, the speed of Qi wireless charging is also much faster, starting at more than 5W, the standard can reach 45W, suitable for mobile phones, tablets and other devices, NFC charging is suitable for Bluetooth headsets, bracelets, smart car keys, etc., and it is charging + data sync at the same time, the fields that can be used in the future are very wide. It is expected that 100 million devices will support NFC wireless charging in 2026.
