Why not use them as a business card you keep in your wallet and let people tap to get you business contact details, social media or your linkedin profile. The NTAG215 chip is used for the popular Amiibo toys for Nintendo Wii U, Switch and 3DS Package Contents: 10 x Blank Card (NTAG215) in plastic wrap sleeve Notes: Some applications will not allow rewriting, and will lock the tag/card.
