SESAME TOUCH is an add-on authentication device that works with the smart lock "SESAME" series. It allows you to lock and unlock your door without a smartphone by simply holding up your fingerprint, IC cards like Suica and PASMO, NFC tags, or smartwatches. I'm selling this because I've upgraded to a new one. It has a simple black rectangular design and can be installed with 3M tape. Everything in the photos is included.
