The Flipper Zero, a device capable of reading and cloning various wireless protocols, has been highlighted for its multiple uses. It can read NFC signals, clone RFID cards and fobs, and control consumer devices with infrared remote controls. The device's capabilities include testing the functionality of remote controls and doorbells, as well as cloning hotel room cards to avoid juggling multiple physical cards.

However, it is essential to note that the Flipper Zero cannot decode encrypted security codes on credit and debit cards, making it impossible to clone bank cards. Additionally, some RFID cards and tags can be locked to prevent their security keys from being extracted, but the Flipper Zero may bypass these mechanisms in certain situations.
