How to Secure a Laboratory with Access Control Technology

Laboratories contain some of an organization’s most valuable and sensitive assets, from research data and proprietary formulations to hazardous materials, expensive equipment, controlled substances, and biological samples. Protecting those assets requires more than traditional locks, shared access cards, or manual sign-in sheets.

A well-designed laboratory access control system helps organizations control who can enter a facility, restrict access to higher-risk areas, manage employee and visitor credentials, and maintain records of access activity.

Effective lab security is rarely based on a single technology. Instead, it combines electronic access credentials, properly configured readers and controllers, physical security measures, monitoring, visitor procedures, and clearly defined access policies.

For security integrators and facility teams, the challenge is determining which credential technologies and access strategies are appropriate for each area of the laboratory.

This guide explains the major components of lab access control, including proximity cards, smart credentials, MIFARE DESFire technology, multi-technology credentials, zone-based access, visitor management, and considerations for regulated laboratory environments.

Why Laboratory Security Requires a Layered Approach

A laboratory is not a typical office environment. Depending on the facility, unauthorized access could expose intellectual property, controlled materials, sensitive research, biological samples, equipment, or confidential information.

Threats can also originate inside an organization.

Lab Manager Magazine identifies several types of insider security risks, including individuals acting maliciously, employees influenced by outside parties, and personnel who unintentionally create vulnerabilities through actions such as sharing credentials or propping open secured doors.

For that reason, effective laboratory security typically uses multiple layers of protection rather than relying solely on the credential presented at the door.

Those layers may include:

If one security measure fails, additional layers remain in place.

Common Laboratory Access Control Vulnerabilities

Several problems can weaken an otherwise well-designed lab security system:

Propped doors: A credentialed entrance provides little protection if the door is routinely held open.

Shared credentials: When multiple employees use the same card or fob, access events can no longer be reliably associated with an individual.

Traditional keys: Physical keys can be copied, lost, or retained after an employee leaves and generally cannot be electronically deactivated.

Uncontrolled after-hours access: Laboratories operating around the clock may require different access permissions or additional monitoring outside normal working hours.

Unrestricted storage areas: Chemical storage, specimen storage, server rooms, equipment areas, and other sensitive locations may require separate access permissions from the general laboratory.

The goal is not simply to secure the building entrance. It is to control access appropriately throughout the facility.

Choosing Access Credentials for Laboratory Security

The access credential is the card, fob, mobile credential, or other identifier presented to an access control reader.

Choosing the appropriate credential technology depends on several factors, including:

For facilities with established access control systems, compatibility is especially important. A credential must match the technology supported by the reader and access control system.

125kHz Proximity Cards for General Lab Access

125kHz proximity credentials remain widely deployed in commercial, institutional, and industrial access control systems.

These credentials transmit identification data to a compatible proximity reader and offer simple, fast access for employees who frequently move through controlled doors.

For laboratories with existing 125kHz reader infrastructure, proximity credentials can provide a practical and economical solution without requiring immediate replacement of installed readers.

ID Enhancements supplies a broad selection of 125kHz proximity credentials, including ISO proximity cards, clamshell cards, key fobs, and compatible credential formats for many existing access control systems.

Common applications include:

Because traditional 125kHz proximity technologies generally do not provide the same cryptographic protections available with modern smart credential platforms, facilities evaluating higher-security applications may want to consider a migration to smart card technology.

Smart Cards for Higher-Security Laboratory Areas

Contactless smart credentials generally operate at 13.56MHz and can support more advanced security features than traditional low-frequency proximity credentials.

However, not all 13.56MHz credentials provide the same level of security.

Technologies such as HID iCLASS, HID Seos, MIFARE Classic, and MIFARE DESFire differ significantly in architecture, encryption capabilities, memory, authentication methods, and reader compatibility.

For that reason, credential selection should be based on the specific access control system and security requirements rather than frequency alone.

Modern smart credential platforms can provide features such as encrypted communication, mutual authentication, protected credential data, and support for multiple applications.

These capabilities can make smart credentials appropriate for higher-risk areas such as:

ID Enhancements stocks multiple 13.56MHz smart credential technologies, including HID iCLASS and Seos-compatible products as well as MIFARE and MIFARE DESFire credentials.

MIFARE DESFire Credentials for Advanced Security Applications

For facilities requiring stronger contactless credential security, MIFARE DESFire provides advanced authentication and encryption capabilities.

MIFARE DESFire EV3 supports AES encryption and multiple applications on a single credential. Depending on system configuration, a single DESFire credential may support applications such as physical access control, identification, time and attendance, or other compatible systems.

DESFire EV3 also incorporates security and privacy enhancements compared with earlier generations of contactless credential technology.

These capabilities make DESFire credentials particularly relevant for organizations planning modern access control deployments or migrating from older credential technologies.

Potential applications include:

ID Enhancements offers a range of MIFARE DESFire 13.56MHz credentials, including ISO cards, key fobs, tags, and other form factors.

Reader and system compatibility should always be confirmed before changing credential technologies.

Multi-Technology Cards for Laboratory System Upgrades

Many laboratories do not upgrade every access control reader at the same time.

A facility may have legacy 125kHz proximity readers at older entrances while newer areas use 13.56MHz smart card readers. Replacing every reader simultaneously may not be practical because of budget, scheduling, or operational requirements.

Multi-technology credentials can provide a practical migration path.

These cards incorporate more than one credential technology into a single physical card, allowing employees to use one credential across compatible legacy and newer readers during a system transition.

For example, a facility moving from a legacy proximity system toward DESFire technology may be able to deploy an appropriate dual-technology credential while replacing readers in phases.

This approach can:

ID Enhancements offers multi-technology credential options, including Allegion/Schlage DESFire multi-technology cards and other dual-technology credentials designed for mixed reader environments.

For facilities planning an access control upgrade, determining the technologies used by both the existing and future readers is one of the most important steps in selecting the correct credential.

Building a Zone-Based Laboratory Access Control Strategy

Not every area of a laboratory carries the same level of risk.

A lobby, employee break room, research laboratory, chemical storage area, and server room should not necessarily have identical access requirements.

Zone-based access control divides a facility according to risk and operational need, then assigns access permissions accordingly.

This supports the principle of least privilege: employees receive access only to the areas necessary for their responsibilities.

Role-Based Access Control (RBAC) can further simplify credential management by assigning permissions according to job function rather than configuring every door individually for every employee.

A laboratory might use a structure similar to the following:

Zone	Example Areas	Possible Credential Approach	Relative Security
General Access	Lobby, hallways, break rooms	Proximity or smart credential	Standard
Controlled Access	Lab suites, shared equipment rooms	Smart credential	Elevated
Restricted Access	Chemical storage, sensitive research areas	Encrypted smart credential; MFA where appropriate	High
Highly Restricted	Server rooms, vaults, specialized containment areas	Strong authentication + detailed access monitoring	Maximum
Visitor / Temporary	Approved meeting or work areas	Time-limited credential	Monitored

The appropriate authentication method should be determined by the facility’s risk assessment, regulatory requirements, safety policies, and access control infrastructure.

Containment classifications such as BSL-2 or BSL-3 should not, by themselves, be interpreted as prescribing one particular card technology. Facilities should determine access requirements based on applicable biosafety guidance, institutional policy, risk assessment, and regulatory obligations.

Physical Security Technologies That Complement Access Credentials

Credentials are only one part of a laboratory access control system.

NIST guidance for physical access control emphasizes the importance of combining credentials with the hardware, software, monitoring, and procedures required to control entry effectively.

Depending on the facility, complementary technologies may include:

The strongest laboratory security programs combine appropriate technology with documented policies and employee training.

Managing Visitor and Contractor Access

Visitors, vendors, service technicians, and contractors often need temporary access to laboratory facilities.

Temporary access should generally follow the same principle of least privilege used for employees: provide access only to the locations required and only for the period required.

A laboratory visitor-management process may include:

Temporary credentials should not automatically inherit the access privileges of permanent employee credentials.

Access control platforms that support expiration dates or time-limited permissions can simplify this process because temporary credentials can automatically become invalid after the approved access period.

Laboratory Access Control and Regulatory Compliance

Laboratory security requirements vary significantly depending on the work being performed, the materials involved, the organization, and applicable laws and regulations.

Access control can be one component of a broader compliance and security program.

Frameworks and requirements that may affect laboratory physical security include:

Framework	Potentially Applicable Environment	Access-Control Considerations
HIPAA	Clinical and healthcare environments	Physical safeguards for areas containing systems or information subject to HIPAA requirements
CLIA	Clinical laboratories	Facility and operational controls appropriate to laboratory activities
NIST SP 800-53	Federal information systems and organizations using the framework	Physical access authorization, monitoring, identity management, and related controls
GLP / GMP / GCP	Pharmaceutical, research, manufacturing and clinical environments	Documented procedures, controlled access, and auditability where applicable
Biosafety Guidance	Biological research laboratories	Access restrictions appropriate to containment level, materials, risk assessment, and institutional policy

Depending on the laboratory and applicable requirements, electronic access records can help demonstrate that entry to controlled areas is appropriately restricted and documented.

Facilities should determine specific compliance requirements with their security, safety, legal, regulatory, and compliance professionals rather than assuming that a particular credential technology alone satisfies a regulatory framework.

Choosing Credentials for an Existing Laboratory Access Control System

One of the most common credential-purchasing mistakes is selecting a card based solely on appearance, frequency, or manufacturer.

Two cards that look identical may use completely different technologies or formats.

Before ordering replacement or additional credentials for an existing laboratory access control system, identify as much of the following information as possible:

This information helps determine whether a credential will work with the facility’s existing readers and access control platform.

It is particularly important when purchasing credentials for established systems using HID-compatible proximity formats, iCLASS, Seos, MIFARE, MIFARE DESFire, or multi-technology readers.

For facilities planning an upgrade, documenting both the current credential technology and the intended future technology can also help determine whether a multi-technology credential makes sense during the transition.

Frequently Asked Questions About Laboratory Access Control

What is the most important technology for securing a laboratory?

Electronic access control is an important foundation because it allows organizations to determine who can enter controlled areas and manage those permissions centrally. However, effective laboratory security typically combines access control with appropriate door hardware, monitoring, alarms, visitor management, physical security procedures, and employee training.

What is the difference between a proximity card and a smart card?

Traditional proximity cards typically operate at 125kHz and transmit credential identification data to a compatible reader. They remain common in existing commercial access control systems.

Contactless smart cards typically operate at 13.56MHz and may support additional capabilities such as encrypted communication, authentication, protected memory, and multiple applications. Security capabilities vary significantly among smart card technologies, so the specific platform matters.

Is 13.56MHz automatically more secure than 125kHz?

Not necessarily.

Frequency alone does not determine credential security. Different 13.56MHz technologies use different authentication and encryption methods. When evaluating security, consider the specific credential platform, reader configuration, encryption capabilities, key management, and overall access control architecture.

How do you implement zone-based access control in a laboratory?

Begin by identifying areas according to operational need and risk. Determine which employee roles require access to each area and assign permissions accordingly. An access control platform can then manage these permissions by individual credential or role.

Permissions should be reviewed periodically and updated promptly when responsibilities change.

How quickly can an employee credential be deactivated?

In a properly configured electronic access control system, an administrator can generally disable a credential through the management platform without physically recovering or replacing door locks.

Actual update timing depends on the access control architecture, controller connectivity, and system configuration.

What credentials work with both legacy 125kHz readers and newer 13.56MHz readers?

A compatible multi-technology credential may support both technologies within one card. The exact credential required depends on the existing 125kHz system and the 13.56MHz technology supported by the newer readers.

Always verify compatibility before ordering.

Can laboratory access control help with regulatory compliance?

Yes, when properly implemented as part of the facility’s overall compliance program. Electronic access control can help restrict entry to sensitive areas and provide access records where documentation is required or useful.

The specific controls required depend on the laboratory and applicable regulatory framework.

How should visitor access be managed in a secure laboratory?

Visitors should generally receive only the access required for their visit and only for the authorized period. Depending on the facility, this may involve host approval, identity verification, time-limited credentials, escort requirements, restricted access zones, and documented entry and exit.

Build a More Secure Laboratory Access Control System

Securing a laboratory starts with understanding the facility, identifying areas of differing risk, and selecting access control technologies appropriate for those environments.

For some facilities, existing 125kHz proximity credentials may continue to provide an effective solution for general employee access. Others may be moving toward modern smart credential technologies such as HID Seos or MIFARE DESFire. Facilities with both legacy and modern readers may benefit from multi-technology credentials during a phased migration.

The important point is that access credentials must be selected for the system in which they will be used.

ID Enhancements supplies access control credentials for security professionals, integrators, businesses, institutions, and organizations using a wide range of reader technologies and access control platforms.
