UltraSecure proximity cards were designed by Ultra ID of Weymouth, United Kingdom, to simplify the process of deploying additional or replacement cards at any secure facility. They seamlessly integrate with all existing proximity systems. An advanced read/write data chip allows the card to hold one of 137 billion unique security codes. The chip is compatible with 26-40 bit proximity systems. The cards have a thin form factor that matches the durability of thicker cards. The company has streamlined the supply chain so users can receive custom-programmed shipments of up to 10,000 credentials from its international manufacturing network in less than a week.
