One Badge, 2 Applications
Companies already using Lathem's popular PC50 proximity time & attendance system can assign their existing badges to the LX100. This customer base can now mainstream, simplify and secure their place of business.

Affordable Security
The LX100 is a keyless proximity door lock that fits standard interior doors. Your customers simply replace your existing cylindrical style door handle with the LX100 for an economical access control system in their business or home.

This package of 5 key fob badges is a perfect addition to any PC50 or LX100 system.  These badge replacements allow employees to attach a small device to their keys which reduces the chances that they are lost or forgotten at home.  If they drive, the employee can't come to work without their badge.  These key fobs work exactly like the badges and have the badge number printed on them for easy entry into the software.
