The PR500-Cotag reads Vanderbilt unique Cotag cards and tags (both active and passive) which offer ultimate convenience and cost-efficiency. It has a reading range of up to 32 cm with an active card and 11 cm with a passive card. The PR500-Cotag has a slim and compact design and blends in well in many environments. When BC-Link is used, two of these readers can be installed to control entries and exits using only one door controller. An additional benefit of BC-Link is that it supports online status monitoring.
