Unlike a standard USB drive, the NFC chips in Skylanders have a limited number of write cycles (roughly 10,000 to 100,000). In 2011, this was fine. By 2024, many original figures are reaching "read-only" status. If your figure dies, a backup bin file allows you to transfer your level 20, fully upgraded character to a new, blank NFC tag.
