1. What Are Access Control Systems?
Access control systems are electronic solutions that regulate, monitor, and secure entry into business premises. They replace traditional keys with more secure methods such as keycards, PINs, fobs, mobile credentials, or biometric scans.
They do three essential things:
Identify who is trying to enter
Authenticate that person
Authorise their access
This helps prevent unauthorised entry, reduce security risks, and create safer, more accountable workplaces.
These systems go by several names depending on the environment:
Office access control systems
Commercial door access control systems
Business access control systems
Commercial building access control systems
While they serve slightly different environments, the core technology is the same: regulating access to protect your space.
2. Why Access Control Matters for Businesses in 2025
Security risks have evolved. Businesses now face:
Theft of stock, tools, or equipment
Unauthorised visitors entering restricted areas
Internal security risks
Liability concerns
Compliance requirements
Access control addresses all of these by ensuring only the right people enter the right areas at the right times.
📊 Supported by data:
According to the Crime Survey for England & Wales, commercial burglary remains a significant threat, with thousands of incidents reported annually. In many cases, unauthorised access points were exploited, something that access control directly prevents.
3. How Access Control Systems Work
Every system, whether simple or advanced, follows the same core process:
Step 1: A user presents their credential
This could be:
A card or fob
A PIN code
A mobile phone (Bluetooth/NFC)
A fingerprint or facial scan (biometric systems)
Step 2: The system verifies identity
The credential is checked against a secure database.
Step 3: The door unlocks (if authorised)
If approved, the door opens. If not, access is denied and the attempt is logged.
Logs help businesses track:
Who entered
When they entered
Which door they used
Whether access was denied
This is essential for compliance, incident reviews, and internal accountability.
4. Types of Access Control Systems for Businesses
There are several types of systems, each suited to different business environments. Below is a complete breakdown.
4.1 Discretionary Access Control
Discretionary Access Control gives the business owner or administrator full control over access permissions. They decide who enters and where. It’s simple and flexible; ideal for smaller businesses.
Suitable for:
Small offices
Studios
Shared working areas
4.2 Mandatory Access Control
Mandatory Access Control is security-focused. Permissions are set at a high administrative level and cannot be changed by staff members. Typically used in environments where sensitive data or high-risk assets must be protected.
Suitable for:
Laboratories
Hospitals
Government buildings
4.3 Role-Based Access Control
One of the most popular systems for businesses. Access is based on job roles, not individual staff members.
For example:
Managers can access all floors
Receptionists can access the main entrance only
Warehouse staff can access storage areas
Suitable for:
Offices
Retail stores
Warehouses
Schools
4.4 Biometric Access Control
These systems use fingerprints, facial recognition, or iris scanning for entry. They offer a high level of security and remove the risk of lost or stolen credentials.
Suitable for:
High-security offices
Data centres
R&D facilities
4.5 Mobile-Based Access Control
Employees use their smartphones to unlock doors via Bluetooth or NFC. It’s convenient and ideal for businesses that want a modern, seamless approach.
Suitable for:
Start-ups
Modern office buildings
Multi-site companies
