Emulators for Wii, Wii U, and PS3 have matured. However, emulators cannot read physical plastic figures. To bypass this, emulator developers added "Portal Passthrough" or "Virtual Portal" support. To use a virtual portal, you need a bin file. You load the bin into the emulator, and the emulator tricks the game into thinking a real figure is hovering over a real portal.
NXP Mifare Classic uses Crypto-1, a stream cipher with a 48-bit key. However, Activision did not use the default transport key (0xFFFFFFFFFFFF). Instead: skylander bin files

Congratulations! You now have a perfect backup. If the figure breaks, you can buy a cheap used Skylander (or a blank NFC tag), erase it, and write your backup BIN to it. Congratulations
Hardware is failing. USB portals are discontinued. Emulators like RPCS3 (PS3) or Dolphin (Wii) cannot read a physical toy over USB easily. Instead, they load Skylander BIN files virtually, tricking the software into thinking a figure is on a portal.
