Question: is this lock NFC accessible?
Document: I saw this digital lock at my friends house and I could imagine my life without keys. Easy installation!! Beautifull design! !
despite the installation leaflet be quite economical in the instructions, the door lock is very easy to install and use. The burglar alarm is also an interesting feature. Just an attempt to open the door with the lock locked is enough to trigger the alarm.
Unfortunately, this lock was not what we expected. The directions came in Korean, only. We ordered it overnight and did not receive it for 3 days! When I got an RMA # to return it, the vendor did not give us credit until I complained and sent him the proof of return. I would not recommend this vendor NOR the lock at this time.We bought the Yale Security YRD240-ZW-0BP instead.
Answer: no
