Biometric and RFID Access Control Systems: What You Need to Know

The Canadians are taking stronger steps to secure their businesses and residences. More and more people are using VizdomTech's biometric and RFID access control systems, which provide fast, reliable access control to keep unwelcome guests out. 

But do you fully understand what these systems do, how they do it, and what their pros and cons are? This is what we are for. We will guide you to understand what you need to know before you make a decision on a security system for your spaces.

Overview of Biometric Access Control Systems

Security solutions called biometric access control systems use a person's biological characteristics to control entry. To initiate with this access control system, your biometric data has been registered first. This data turns into a digital template and is stored securely. 

When entering the system, both records are compared to previous scans. You are granted access after validating a match. If not, entry is denied. 

Common types of biometric identifiers

More frequent variants of biometric systems emphasize the specific human traits that biometric systems are built to identify and provide secure access to a system without the use of keys and cards.

• Fingerprint Recognition: The type uses fingerprint patterns to scan and compare the print with saved data to allow or block access.

• Facial Recognition: It scans facial features such as the eyes, the nose, and the jaw shape. Cameras match the face with stored images.

• Iris and Retina Scanning: The type reads the unique patterns inside the eye. These methods provide strong accuracy for restricted areas.

• Voice Recognition: Analyzes voice tone and speech patterns, and access is only granted after matching recorded voice data.

Each biometric method has a different balance of comfort, speed, and security based on the environment.

Advantages of Biometric Access Control

Biometric access control systems link entry to a real person, which raises trust, control, and safety in daily operations.

• No Cards or Passwords: You do not need to carry cards or keep in mind what passwords are. Your identity is always with them.

• Reliable Identity Verification: Fingerprints and facial recognition are unique to each individual. It mitigates the problem of stolen entry tools and unauthorized sharing.

• Quick Access: Entry is granted in mere seconds, which is ideal for busy workplaces and areas with a lot of people.

• Detailed Access Logs: The system keeps track of who accessed the entry point and at what time. This assists supervisors and managers with activity and presence verifications.

All of these elements help create a protective environment and ease the restrictions for employees, guests, and security personnel.

Drawbacks of Biometric Access Systems

Along with its benefits, biometric systems bring a number of practical problems during their installation, daily operations, and their acceptability by the users.

• Concern for Privacy: There can be concern about how biometric information will be used or with whom the information will be shared.

• High Initial Investments: The system comes with a high price tag for smaller companies, including the necessary hardware, software, and system integration.

• Scan Sensitivity: Screen glitches, poor environmental light, and noise may create false negatives or a timed-out screen.

• Discomfort of Users: Some may not have any idea of how to cope with this tool.

All such problems may be mitigated with the proper setup, transparent communication, and good planning.

Overview of RFID Access Control Systems

A type of access management system called Radio Frequency Identification (RFID) automatically recognizes and monitors objects using electromagnetic waves. 

The majority of RFID frameworks consist of a microchip and an antenna (referred to as a tag), an antenna paired with a reader, and a control server that performs the access management function.

When an RFID tag is presented to a reader, the system retrieves the tag’s data and compares it with its stored data. If a match is successful, access is granted to the user.

Components of an RFID system

An RFID system relies on three main components that work together to provide secure and organized access control systems:

• RFID Tags / Cards: Your tag or card stores unique information about you. It acts as your personal digital key to access the areas you are authorized for.

• Readers: Readers detect and read the data stored on your tag. They send your information to the control system for verification.

• Control Panels and Software: The control server looks at your tag and matches it with stored records to see if you are allowed to enter.

With these parts working together, you get fast, safe, and reliable access to your workplace or any restricted area.

Types of RFID Access Control Systems

There are different types of RFID systems, and their variations affect the level of security, speed, and distance of access.

• Low-Frequency (LF) Systems: LF systems are ideal in terms of distance and are suitable for small offices or enclosures with basic security needs.

• High-Frequency (HF) Systems: HF systems offer quicker reading capability and stronger security. They are useful in office, school, or mid-traffic situations.

• Ultra-High-Frequency (UHF) Systems: UHF systems are suitable for larger distances as they read at further distances. They are appropriate for parking, large warehouses, or high-density situations.

• Passive vs. Active RFID tags: Active tags have a battery, which also enables further reading distance. Passive tags are smaller and less expensive, and depend on the tag-on-reader emission.

Choose wisely so you can properly control your access and retain the necessary level of security.

Advantages of RFID Access Control Systems

The advantages you can access using RFID systems include:

• Contactless Access: You can scan your tag without having contact with anything. This speeds up entry and reduces damage to doors or locks.

• Easy Management: Tags can be instantly issued, blocked, or removed. Your access control systems remain flexible and are fully in your control.

• Fast Entry: Your tag is read in seconds without interrupting the flow of your team, and the system keeps moving.

• Clear Records: You get access to all entries. This improves your management and auditing to know who, when, and what they accessed.

RFID gives you security and control while making daily access quick and simple.

Limitations and Security Risks of RFID Systems

The usefulness of RFID technology comes with certain risks: 

• Card Loss or Theft: If a tag is lost, another person could use it, which is why irretrievable cards should be blocked immediately.

• Risk of Cloning: RFID tags can be duplicated, which is why tags that are more sophisticated, encrypted, and harder to copy should be used for more secure areas.

• Limited Identity Verification: The system only checks the tag, not you personally. So, this means another person could use your tag if you do not keep it secure.

• Signal Interference: Metal surfaces, walls, or electronic devices can prevent your tag from being read correctly.

Knowing these risks is part of safe access control systems and access management systems.

Applications of Biometric and RFID Access Control

The use of systems with biometrics and RFID is almost ubiquitous in all sectors and industries.

• Corporate Offices:  In office environments, these systems control employee access, block unauthorized access, and record attendance and movement.

• Educational Institutions: Schools and colleges use them to track attendance of both students and teachers. In addition, to control the access given to students, teachers, and other staff. 

• Healthcare Facilities: In hospitals, systems like these are used to restrict access to patient data, operating rooms, and medication storage areas.

• Government and Military: High-security areas use biometrics and RFID to protect sensitive data, equipment, and personnel. You can control entry and track movements easily.

• Residential Buildings: In apartments and gated communities, these systems manage resident access, replace lost keys, and keep buildings safe.

These systems provide flexible and reliable access control.

Legal, Ethical, and Privacy Considerations

When using RFID and biometric systems, several ethical considerations must be put in place, such as:

• Data Protection Law: In order to avoid a data breach, you must comply with the laws of your jurisdiction relating to personal data.

• User Consent: To respect privacy and transparency, you must notify the users and obtain consent prior to collecting a person's biometric data.

• Secure Storage of Biometric Data: Data needs to be safely protected from unauthorized access, alteration, data breaches, or leaks that could harm the individuals involved.

• Ethical Use of Surveillance Technologies: Unnecessary monitoring must be avoided, and access to control must be granted where needed.

Taking these legal, ethical, and privacy concerns into account helps you use biometric and RFID systems responsibly.
