RFID Access Control Cards are a requirement for controlled user access in almost every company today. The specialized UID Access Control Card not only works with your building’s access control system, but it can also be used for user identification for the Pi Software Suite. With two frequencies available, one frequency is used for user access to a room or building, while the second frequency is read by the UID System for access to the Pi Software. Each frequency is unique and 100% secure. Contact UID at info@uidevices.com or 224.444.8484 for more information.
