The 37-Bit Format A901058A for ADT is a structured and reliable credential format designed for use within ADT® access control systems and compatible environments. With its 37-bit configuration, this format provides a larger credential capacity than standard formats, making it well-suited for organizations that require organized user management and room for future expansion.
A901058A is commonly implemented in systems where both facility code and card number segmentation are important for maintaining clear credential organization. This allows administrators to assign and track credentials across different departments, locations, or user groups while maintaining system consistency and control. The format is particularly effective in commercial, institutional, and multi-tenant environments where structured access control is essential.
Designed for dependable performance, the 37-bit A901058A format works seamlessly across proximity cards, key fobs, and RFID credentials, ensuring consistent read accuracy and smooth integration with ADT-based systems. Its expanded bit length helps reduce duplication concerns while supporting larger user populations over time.
RapidPROX® credentials programmed with the A901058A format offer a practical and cost-efficient alternative to OEM credentials while maintaining full compatibility with ADT systems. Whether you're adding new users or replacing existing credentials, this format provides a stable, scalable solution for managing access control with confidence.
