Introducing the amiibolink Bluetooth Keychain - your ultimate solution for unlimited swiping without any limitations. With this device, you can swipe repeatedly 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 sensor technology is both sensitive and fast. Pros: The one-button option makes this device incredibly easy to use. The smart sensor technology, combined with infinite swiping and Bluetooth connectivity, ensures high endurance. As a result, this device is small and lightweight, making it the perfect choice for everyone. Cons of traditional cards: Regular cards can be difficult to carry around, are expensive as a complete set, and have limited storage capacity, allowing only one data per card. Additionally, disposable cards limit their swipe times. These issues are irrelevant with amiiboLink. Mode Settings: To set the mode, open the app and click on profile -> settings -> mode settings. Random Mode: In this mode, you generate new amiibo data by pressing the button based on the current bin file, which essentially creates a copy of a new card. Sequential Mode (File Switching Mode): In this mode, you automatically switch to a new bin file by pressing the button, and you can store up to four bin files offline. Firmware Upgrade Mode: Press and hold the button to turn on a solid green light, which enters the firmware upgrade flashing mode. Download the firmware upgrade package and use the app to upgrade.
