Balancing the benefits of mobile credentials and traditional security

Access control technology offers security professionals diverse options for protecting facilities and assets. While mobile credentials have gained popularity, traditional methods like cards and fobs remain crucial in comprehensive security strategies. Understanding the strengths of each approach helps organisations implement the right solutions for their specific requirements.

Understanding today’s credential options

Modern access control systems support various credential technologies that serve different needs and environments:

• Proximity cards provide reliable operation with simple presentation to readers.
• Smart cards offer enhanced security through encryption and multi-application capability.
• Key fobs deliver similar functionality in compact, durable formats that conveniently attach to keyrings.
• Mobile credentials transform smartphones into access tokens, creating new possibilities alongside established methods.

Mobile credential adoption continues to grow. According to the HID 2024 State of Security and Identity report, 72% of security professionals identified mobile identity as a top trend, with 64% of organisations implementing mobile ID solutions to some degree. This growth reflects the increasing role of smartphones in professional environments and the BYOD (Bring Your Own Device) movement, where personal devices serve multiple functions.

However, this growth doesn’t diminish the importance of traditional credentials, which continue to excel in many scenarios. The most secure facilities often employ multiple credential types, selecting the right tool for each specific application rather than applying a one-size-fits-all approach.

When mobile credentials excel

Mobile credentials offer distinct advantages in several scenarios:

• Remote management: The ability to issue credentials remotely improves efficiency for distributed workforces, allowing administrators to provision access instantly without requiring employees to visit a central location.
• Enhanced security layers: Mobile devices create additional protective factors, typically combining something they have (the device), something they know (PIN/password), and something they are (biometric verification).
• Immediate revocation: Security teams can revoke access immediately through centralised management systems if an employee loses their mobile device or leaves the organisation.
• Improved user experience: For employees who already carry smartphones, mobile credentials reduce the number of items they need to manage, often resulting in better compliance with security protocols

Where traditional credentials remain essential

Despite the advantages of mobile options, traditional credentials remain indispensable in many environments:

• High-security facilities: Government installations, research laboratories, and financial institutions frequently maintain card-based systems for their most sensitive zones due to established security protocols and controlled distribution.
• Reliability: Physical credentials function without concerns about battery life, network connectivity, or software compatibility, making them ideal for applications where dependable access is paramount.
• Infrastructure compatibility: Cards and fobs work with extensive installed reader networks, allowing organisations to maintain consistent access control across facilities with varying technological capabilities.
• Challenging environments: Industrial settings, construction sites, or laboratories with hazardous conditions often present challenges for mobile credentials, as employees may need to leave personal devices in lockers or secure areas.
• User preferences: While many staff members embrace smartphone-based solutions, others prefer physical credentials for simplicity and familiarity, supporting better inclusion across age groups and technology comfort levels.

Implementation strategies for mixed environments

Most organisations benefit from strategically implementing both credential types based on specific operational requirements. Multi-technology readers that support cards, fobs, and mobile credentials provide maximum flexibility during technology transitions. This approach allows security teams to deploy the right credential type for each application while maintaining system cohesion.

Zone-based implementation often proves effective, with mobile credentials serving general areas while traditional options remain for specialised functions. For example, an office building might implement mobile access for main entrances and common areas while maintaining card access for server rooms, executive suites, or research laboratories.

User population assessment helps determine appropriate credential distribution. Some employees might receive mobile credentials based on their roles or technical proficiency, while others continue using cards or fobs. This targeted approach ensures that each staff member gets the credential type best suited to their specific needs and responsibilities.

Network infrastructure requirements deserve careful consideration during implementation planning. While mobile credentials can function offline once provisioned, reliable connectivity enhances the user experience during initial setup and updates. Security teams should evaluate Wi-Fi coverage and cellular reception in key areas to ensure smooth operation.

Practical considerations for security professionals

When evaluating credential options, security managers should consider several practical factors beyond technical specifications:

• Budget implications: While mobile credentials potentially reduce long-term costs through decreased card production and management, they may require initial infrastructure investments
• Compliance requirements: Regulated industries often have specific authentication requirements that influence credential choices, particularly in financial institutions, healthcare, and government contracts
• Disaster recovery: Comprehensive security strategies should account for system failures or emergency scenarios, with traditional credentials often providing reliable backup options during network outages
• Vendor expertise: Partners with experience deploying both mobile and traditional solutions can provide valuable guidance during system design and rollout, helping organisations maximise the benefits of their credential strategy

The most effective access control systems combine mobile and traditional credentials in ways that leverage their respective strengths. Rather than viewing these technologies as competing alternatives, security professionals increasingly implement complementary approaches that enhance security and user experience.

Mobile credentials offer convenience, multi-factor authentication, and remote management advantages. Traditional cards and fobs provide enduring reliability, established security protocols, and universal compatibility. By understanding the distinct benefits of each approach, security managers can develop credential strategies that address their specific operational requirements.

As security technology improves, the organisations that thrive will select the right tools for each application rather than pursue technological uniformity for its own sake. This balanced perspective ensures that access control systems remain secure, user-friendly, and aligned with operational needs – regardless of which credential technologies they employ.
