What is the role of qr codes in toy authentication?

In toys‑to‑life games, QR codes act as a simple visual identifier. The game’s camera scans the code, reads a unique string, and matches it to a database of registered figurines. This confirms that the toy is authentic and not a counterfeit. Once authenticated, the game can determine the figurine’s proximity and, in some designs, write progress or settings back to the toy’s storage. The use of QR codes provides a low‑cost, easy‑to‑implement method for ensuring only legitimate figures are used, helping developers maintain control over in‑game content and player experience.
