How is the "contactless business card" implemented?
Good day to everyone, I came across a similar stray on the Internet https://toch.company/
In 2 words: sticker (2cm diameter, bulge somewhere around 1mm). You bring your smartphone to it - it redirects to the site. In general, something similar to a qr code, but you do not need to point the camera.
Actually the question is: what's inside (stickers)? How is it implemented and how is it programmed? In general, I will be grateful for any comments :)

NFC tag.
3. Turn on NFC in the settings. Without the NFC function enabled, Toch will not work. Make sure it's enabled.
