THE BUYING GUIDE
Access control and time attendance can share devices, but they solve different tasks. Define who may enter each area, which credentials will be used and how records need to be managed. Then check the terminal, controller, reader and software combination against the door hardware and operational requirements.
Describe the job, the installation environment and the equipment already on site. Compare the exact model specifications before choosing; a collection name alone does not establish compatibility or included features.

Choose the credential types actually supported by the device and check user and record capacities.
Confirm door count, reader interfaces and the exact compatible lock and exit-device arrangement.
Check the required schedules, reports, enrolment process and software support separately.
Plan supported power supplies, cabling and mounting. Have the complete door arrangement reviewed for the site requirements.
