Visitor Management Systems: Integrating With Access Control

Visitor Management Systems: Integrating With Access Control

by Mike Boehm on November 12, 2025

Managing visitors effectively is no longer just about signing a paper logbook — it’s about security, compliance, and a seamless user experience. Modern visitor management systems (VMS) integrate directly with electronic access control systems, allowing organizations to issue secure temporary credentials, monitor entry activity, and maintain accurate visitor logs.

When paired with standard proximity formats such as the 26 bit H10301 format, a visitor management system can automatically assign access permissions to temporary badges, key fobs, or adhesive tags that work with the same card readers used by employees.

Why Integration Matters

Integrating visitor management software with your access control system improves both security and operational efficiency. Instead of handing out paper badges or unsecured cards, visitors can be issued encoded proximity credentials that expire at the end of their visit — preventing unauthorized re-entry and simplifying compliance tracking.

For example, a facility using a 125 kHz 26 bit H10301 format system (the industry’s most common open Wiegand standard) can issue temporary proximity cards or fobs encoded to that same format. These cards will read properly on HID, and all 26 bit H10301 proximity readers — no special setup or reprogramming required.


How the 26 Bit H10301 Format Fits In

The 26 bit H10301 format has become the universal baseline for access control credentials. Its data structure includes:

  • 1 parity bit (leading)
  • 8-bit facility code (range: 0–255)
  • 16-bit card number (range: 0–65,535)
  • 1 parity bit (trailing)

This simplicity and wide support make 26-bit ideal for visitor credentials, short-term access cards, and cross-system compatibility. Many visitor management systems, including those used in offices, schools, and healthcare facilities, can automatically encode or assign 26-bit card numbers when integrated with compatible printers and encoders.

By standardizing on 26-bit, administrators can ensure visitor badges and long-term employee IDs both work seamlessly across the same physical access points.


Common Reader Compatibility

The 26 bit H10301 format works with almost every mainstream 125 kHz proximity reader on the market. Common examples include:

  • HID ProxPoint Plus 6005
  • HID MiniProx 5365
  • HID ThinLine II 5395
  • HID ProxPro 5355
  • HID Signo 20, 40, and 40K Series

This universal compatibility allows visitor management systems to issue temporary credentials that can be used immediately, without new hardware or wiring changes.


Practical Use Cases

Corporate Offices: Automatically print visitor badges encoded to your 26-bit access format, granting timed access to meeting rooms or lobby areas.

Healthcare Facilities: Assign 26-bit encoded adhesive tags to contractors or medical representatives for same-day access, then deactivate them at checkout.

Educational Institutions: Integrate visitor management software with existing HID readers to provide secure temporary access for guests or event staff.

Government Buildings: Use pre-encoded 26-bit proximity fobs or cards for temporary staff and external vendors to maintain compliance and traceability.


Hardware and Credential Options

AuthorizID offers a wide selection of 26 bit H10301 format credentials, including:

  • Printable ISO PVC cards (HID 1386 compatible)
  • Durable key fobs (HID 1346 ProxKey III equivalents)
  • Adhesive tags (HID 1391 MicroProx equivalents)
  • Flexible wristbands for visitor or gym access applications

Each credential type can be custom-encoded with your facility code and card number range for full compatibility with your existing access control system.


Integration Benefits

  • Improved security: Eliminate manual visitor passes and track activity automatically.
  • Enhanced experience: Simplify check-in and streamline temporary credential issuance.
  • Full compatibility: Use standard proximity technology like 26-bit H10301 for both staff and visitors.
  • Scalability: Add printers, encoders, or software integrations as your facility grows.
