I am an Account Manager with MJK Industrial, based in New Taipei City, Taiwan. MJK is a manufacture of specialty locks mainly used in the gaming, vending and casino industry. With more sophisticated requirements from our clients, the locks we make are usually more unique and provided added security and key functionality.

At this time, we are very interested in engaging a partner to manufacture a smart lock. Feel free to contact me with any questions.
