Questions

Is there a KiCad symbol and footprint for the NF522?

Yes. The symbol is EasyEDA_Cloud:NF522 and the footprint EasyEDA_Cloud:QFN-32_L5.0-W5.0-P0.50-TL-EP3.3, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the NF522?

QFN-32-EP(5x5), with 33 pins. Its footprint is drawn on this page.

Where can I order the NF522?

JLCPCB lists it as part C42413378, with 9,524 in stock; the sellers' links on this page open their listings.

What can replace the NF522?

Parts like it in the library: the ST25DV04KC-IE6S3 by STMicroelectronics, the MFRC522 by JSMSEMI, the CLRC66303HNY by NXP Semiconductors and the PN7150B0HN/C11002Y by NXP Semiconductors. Check their datasheets: a part that fits the footprint may still differ in its ratings.
