@strypey It can read and emulate NFC cards, RFID tags, Dallas iButtons, and infrared remotes. It can receive and decode various radio devices such as garage door remotes and some car key fobs. Depending on encryption (or lack of), and the radio regulations in your area (it will refuse to transmit on licensed frequencies), it can retransmit captured radio transmissions. For example, you can download and transmit a radio code that will cause nearby Teslas to pop open the charging port door. It can communicate with a companion app on your phone over Bluetooth so you can manage saved data and install third-party functionality (apps) onto it, but doesn't require that (can operate fully standalone).
It's a cute device that does a little bit of everything in the "transmit/receive data" category, but much like a real Swiss Army Knife, the “full-size version” of each included tool will always be far superior. But it fits in your pocket and has a cute dolphin avatar.
