I just googled what NFC chip is. WHAAAT?? Are u living in 2050 there in Indonesia already? damn some cyberpunk shit hahah.
I use nail glue like this. They stick well as long as you prep the nails good and make sure there's no oil and such before you apply. I only tried using glue when my fake nails fall apart and I want a quick fix, but I haven't really tried using it as a "base" or direct on top of the nail so not sure how long they would last. As far as I remember, it lasts for like 2 days even when I do chores, but that's cos it was just a quick fix.
Thanks for the shoppe link! that's faster. Also yeah, NFC chips/stickers on fingernails are pretty old. Like this one: https://www.hackster.io/news/how-to-embed-nfc-chips-into-your-acrylic-fingernails-for-unlocking-your-phone-and-much-more-51ea87d6a169 it has been around for 3 years. Though, one of the use cases was for unlocking the phone. I got interested because there's a saloon in Dubai that does it. The NFC chip will show the social media profiles which is advancement for more than just unlocking phone. NFC chip sticker is also cheap; I didn't know that it was going to cost a few cents. It's a fun project and I think you should try it out since you practically have the nails and the glues :D
Wow I've never heard of it really. Haha. But maintenance is probably not easy as most nails last at least 3-4 weeks. My concern is more on protecting it lol
