Hirsch 4082 Prox Key Fob - 33 Bit D10202
The Hirsch 4082 Proximity Key Fob is designed for organizations utilizing 125kHz proximity credential technology with 33-bit D10202 formatting. This compact credential is commonly used in commercial facilities, residential properties, healthcare campuses, educational institutions, and industrial environments where a small, portable access control device is preferred over traditional cards.
The key fob form factor allows users to easily attach credentials to keyrings, lanyards, or badge reels, making it ideal for employees, contractors, and authorized personnel who require consistent access without carrying a standard ID card. Despite its compact size, the fob delivers reliable read performance in compatible 125kHz proximity reader systems and is built for daily wear and tear.
Organizations ordering programmed D10202 credentials will typically need to provide their assigned facility code and credential numbering range to ensure compatibility with their existing access control system configuration.
