To understand the key_retail.bin file, one must first understand how an Amiibo works. Inside every Amiibo figure is an NTAG215 NFC chip. When you scan an Amiibo on your Nintendo Switch, the console reads a .bin file—a raw data dump of exactly what is stored on that chip. However, this data is not just plain text. Nintendo encrypts the sensitive information inside, which includes character identity, game-specific progress data, and authentication signatures.
Key-retail bin downloads offer several benefits, including:
Users point the emulator's settings to their local key-retail.bin file. : Hold your NTAG215 card/sticker against your phone’s

If you download a raw 540-byte .bin Amiibo dump from the internet and try to write it directly to an NFC tag using a phone, you might fail. Many apps require the file to be processed. The DeepWiki documentation notes: "Essential files like key_retail.bin , locked-secret.bin , and unfixed-info.bin are required for this conversion process, as they contain the necessary cryptographic keys" .

Amiibo data is specifically designed to work only with NTAG215 tags. Other tags (like NTAG213 or NTAG216) will not work, even if the .bin file is correct. Conclusion
Save the resulting dump directly to your local device storage as a .bin file. Legal and Safety Warning Regarding Public Downloads
