Abstract
A system is provided for upgrading a legacy security system having a legacy control panel and a legacy card reader, without interfering with legacy system operation. A new control panel is installed between the legacy card reader and the legacy control panel. Also, a new token reader is installed next to the legacy card reader and connected to the new control panel. The new control panel passes credentials it receives from the legacy card reader to the legacy control panel, avoiding interference with legacy system operation. When the new control panel receives credentials from the new token reader, it evaluates them against an access rights list administered independently of the legacy access rights list. When the new control panel determines that an access request should be granted, it sends a memorized legacy credential associated with full access rights to the legacy control panel, causing it to open the door.
