NFC tags aka MIFARE Classic and the like? Those would be susceptible to cloning with something like Chameleon Tiny and to repeater attacks. You need actual contactless smartcard support if you want to use it for something serious. Otherwise be ready for LockPickingLawyer making an example of you of how not to do it, he already has similar videos about it.

PC/SC compatible stuff is out there if you know where to look (not affiliated with them) https://webshop.d-logic.net/products/nfc-rfid-reader-writer/...

(ignore the cards they include with the order, proper contactless smartcards or something like an OMNI ring https://store.nfcring.com/products/omni need to be purchased separately)
