Description: Introducing the amiibolink Bluetooth keychain - your ultimate solution for unlimited swiping without any restrictions. With this device, you can swipe repetitively without changing the time and simulate an unlimited number of amiibo cards. It includes all amiibo cards on the market and updates to the latest amiibo are available as soon as possible. The smart sensing technology is both sensitive and fast. Advantages: The one button switch option makes using this device incredibly easy. The smart sensing technology, coupled with infinite swiping and Bluetooth connectivity, ensures high endurance. As a result, this device is small and light, making it the perfect choice for everyone. Traditional Card Disadvantages: Ordinary cards can be difficult to carry around, are expensive as a full set, and have limited storage capacity, allowing only one data per card. Furthermore, single-use cards limit their swiping times. These issues are irrelevant with amiiboLink. Mode Settings: To set the mode, open the app and click on the profile -> settings -> mode settings. Random mode: Under this mode, pressing the button generates new amiibo data based on the current bin file, essentially creating a copy of a new card. Sequential mode (file switching mode): Under this mode, pressing the button automatically switches to a new bin file, and you can store up to four bin files offline. Firmware upgrade mode: Press and hold the button to turn on solid green light, which enters firmware upgrade flashing mode. Download the firmware upgrade package and use the app to upgrade.
