Well this is key_chain_ncf_pcb powered by NT3H2111 in which you can add your linkdln profile or whatever link you want . This project was made to make sharing your linkdln profile more fluent and easier for the user ( you can add a sticker to conver the pcb and make it more professional if wanted ) to do this Just Download the gerber files and print it then have fun

Questions
How big is the NFC PCB?
It measures 50 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the NFC use?
10 parts, built around the NT3H2111W0FHKH. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the NFC KiCad files?
From the Az154za/NFC_Key_chain_pcb repository on GitHub, at the commit this page was made from: the board is PCB/NFC.kicad_pcb and its schematic PCB/NFC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NFC design in my own project?
Its repository states no licence, so its author keeps all rights: ask Az154za before reusing the design.
