SANWA SUPPLY NFC tags (100 pieces)

This is an NFC tag sticker that can be read and written freely.
You can create your own original NFC tag by writing tasks using the dedicated app.
You can also turn Wi-Fi and Bluetooth on/off, or launch apps such as calendars, weather, cooking, and navigation by simply holding the device over the device if you write tasks using an NFC app.
By using Sanwa Supply's original app, the "NFC Easy Setup App," even beginners can easily use NFC tags.
Tasks can be overwritten and their contents can be rewritten any number of times.
It can also be written as "read-only" so that it cannot be overwritten.
They are also ideal for use as promotional items, such as writing your company URL or campaign page URL and sticking them on posters or postcards.
It's small, measuring 23mm in diameter, so you can stick it on a variety of things.
