However, touchless access control completely redefines this process by eliminating the need for any direct physical contact between the user and the access point.

Key Components of Mobile-Based Touchless Access Control Systems

Mobile-based touchless access control systems leverage the capabilities of smartphones to grant or deny access to secured areas. These systems offer a seamless and convenient way for individuals to interact with access points while maintaining a high level of security. Here are the key components that make up mobile-based touchless access control systems:

Mobile Devices as Credentials

The cornerstone of mobile-based access control is the use of smartphones as access credentials. Users can register their mobile devices, and these devices become their virtual keys. The smartphone serves as a secure token for authentication, replacing traditional access cards or physical keys.

Mobile Apps

To facilitate mobile-based access control, organizations typically provide users with dedicated mobile apps. These apps are installed on users’ smartphones and act as the interface for interacting with access points. Users can use the app to request access, receive digital keys, and manage their access permissions.

Proximity Sensors

Proximity sensors are installed at access points, such as doors, turnstiles, or gates. These sensors detect the presence of authorized mobile devices as users approach. Proximity sensors use technologies like Bluetooth Low Energy (BLE), NFC (Near Field Communication), or Wi-Fi to establish a connection with the mobile device.

Authentication Protocols

Mobile-based access control systems employ robust authentication protocols to verify the identity of users. Authentication may involve one or more of the following methods:

Biometrics: Many smartphones are equipped with biometric sensors, such as fingerprint readers, facial recognition cameras, or iris scanners. Users can authenticate themselves by simply using these biometric features.

PIN or Passcode: Users may be required to enter a PIN or passcode on their smartphones as an additional layer of security.

Multi-Factor Authentication (MFA): Combining multiple authentication methods, such as biometrics and PINs, enhances security by requiring users to provide multiple forms of verification.

Secure Communication Protocols

To ensure the security of data transmission between mobile devices and access points, mobile-based systems use secure communication protocols like HTTPS or TLS. These protocols encrypt data, protecting it from interception or tampering.

Cloud-Based Management

Cloud-based management platforms are often employed to centralize the administration of mobile-based access control systems. This allows administrators to remotely manage user access, update permissions, and monitor access events in real-time.

Access Control Dashboard

Administrators use access control dashboards provided by the system to manage and monitor the access control system. From the dashboard, they can configure access policies, view access logs, and make real-time decisions regarding access requests.

Integration with Existing Infrastructure

Mobile-based access control systems can integrate seamlessly with existing security infrastructure. This includes connecting with security cameras, alarms, and other security devices to enhance overall security and surveillance capabilities.

User Enrollment and Onboarding

User onboarding involves registering users’ mobile devices with the access control system.

User training ensures that individuals understand how to use the system effectively.

How Mobile-Based Access Works

Mobile-based access control systems leverage smartphones as virtual keys, offering a contactless and secure method for granting or denying access to secured areas. Here’s a step-by-step explanation of how mobile-based access works:

User Registration and Enrollment

Mobile App Installation: Users start by installing a dedicated mobile app provided by the access control system provider. This app serves as the interface for interacting with the access points.

User Account Creation: Users create accounts within the app, providing their personal information and creating login credentials. During this process, they may also need to verify their identity using email or other methods.

Mobile Device Pairing: To link their mobile device with the access control system, users often pair their smartphones with access points or the cloud-based management system. This is typically done through Bluetooth, Wi-Fi, or other wireless communication protocols.

Requesting Access

Access Request: When users approach an access point, they use the mobile app to request access to a secured area. This can be done by selecting the relevant access point within the app or by simply being in proximity to the access point, which triggers the request automatically.

Authentication: To proceed, the user must authenticate themselves. This authentication can take several forms, including:

Biometrics: Users may need to use their smartphone’s biometric features (e.g., fingerprint, facial recognition) to verify their identity.

PIN or Passcode: Some systems require users to enter a PIN or passcode within the app as an additional layer of security.

Multi-Factor Authentication (MFA): For added security, users may need to combine biometrics with a PIN or other authentication methods.

Access Verification

Communication with Access Point: Once the user’s identity is confirmed, the smartphone communicates with the access point. This communication can be established through various wireless technologies:

Bluetooth Low Energy (BLE): Bluetooth is commonly used for communication between smartphones and access points, providing a secure and energy-efficient connection.

Near Field Communication (NFC): NFC allows for short-range communication, typically requiring the user to tap their phone near the access point.

Wi-Fi: In some cases, Wi-Fi may be used for communication, especially for remote access control.

Access Decision: The access point receives the user’s request and verifies it against the permissions stored in the system’s database. If the user has the necessary access rights and authentication is successful, the access point grants entry.

Entry and Access Logging

Access Granted: Upon successful verification, the access point unlocks, allowing the user to enter the secured area. This process is fast and seamless, enhancing user convenience.

Real-Time Logging: The system records the access event in real-time, capturing data such as the user’s identity, timestamp, and location. These access logs are invaluable for security monitoring and auditing purposes.

Remote Management and Monitoring

Administrator Control: Access control administrators can manage the system remotely through a cloud-based management platform. From this platform, they can grant or revoke access permissions, update user profiles, and monitor access events in real-time.

Alerts and Notifications: The system can be configured to send alerts and notifications to administrators in case of unusual access events or security breaches, enabling swift responses to potential threats.

Secure Communication and Data Protection

Encryption: To ensure the security of data transmission between the smartphone and the access point, secure encryption protocols such as HTTPS or TLS are used. These protocols protect data from interception or tampering.

User Data Protection: User data, including biometric information, is securely stored and protected within the mobile app and the system’s database. Stringent security measures are in place to prevent unauthorized access to this sensitive information.
