The claims Via News extracted from this document. We point to the source; we don't replace it.
A copper sheet around the lock would act as a Faraday cage, blocking RFID signals and the EM fields an attacker might use to locate it. This is not possible with an RFID reader.
60% confidenceConventional magnetic locks can be opened by any strong magnet once the lock location is guessed, which motivated a gesture-based design.

60% confidenceSparkFun says the silk-screen error misidentifying the SPI connections will be fixed in future board runs.
