: The console uses the amiibo's identifier to determine what data to exchange. This could involve retrieving specific information from the amiibo or sending data to it.
Every amiibo contains an NFC (Near Field Communication) chip. This is a standard off-the-shelf component made by NXP Semiconductors. Critically, standard NTAG215 chips have a fixed memory layout: 540 bytes of user memory divided into 135 pages (4 bytes each).
Because the master key (seed) is static across all Amiibo and the signature mechanism was reverse-engineered, it became possible to generate valid signatures for any NTAG215 chip, provided the lock bits had not yet been set.
