MobileGuard: Your Portable Access Control Solution

MobileGuard, also known as Mob8, is a powerful application designed to transform your Android smartphone into a portable QR-code and Mifare card reader. Whether you're managing access control systems in large facilities or organizing events, this app offers a versatile solution for real-time monitoring and verification of access credentials. MobileGuard works seamlessly with GuardPoint 10-compatible access control systems (ACS), enabling you to validate access cards and QR codes while on the move.

One of the standout features of MobileGuard is its ability to perform impromptu spot checks. By scanning a user's badge or card, the app retrieves essential details such as the user's photo, location, and validation status. This capability is particularly useful for conducting random audits or updating users' locations in real time, a process known as "Mobile Check-in." During emergencies like evacuations, MobileGuard ensures that everyone is accounted for by confirming individual locations, a crucial function for fire mustering procedures.

Offline Operation for Enhanced Flexibility

MobileGuard excels in situations where network connectivity is limited or unavailable. Using a pre-downloaded database snapshot, the app can still function effectively in offline mode. This makes it ideal for environments like coach trips, festivals, or remote locations where internet access may be spotty or nonexistent.

Versatile Card Technologies

MobileGuard supports a wide range of card technologies, making it suitable for various applications. These include:

• 13.56MHz RFID/Proximity cards: Compatible with external or NFC-enabled mobile readers.
• Mifare Desfire: Allows companies to set up unique read keys and security profiles.
• 125kHz Proximity cards: Requires an external reader for compatibility.
• 32-bit QR-Code Tickets/Temporary Passes: Ideal for event management and one-time access.

It's worth noting that the strength of an Android device's NFC field can vary depending on the model and case. For high-volume environments, an external USB-C reader is highly recommended to ensure reliable performance.

Security and Privacy

As access control systems often handle sensitive personal information, MobileGuard prioritizes data protection through several robust mechanisms. The app's settings are secured with an additional biometric prompt when available, adding an extra layer of security. In production environments, it's recommended to establish a secure two-factor authenticated connection to the ACS using mTLSv1.2 or mTLSv1.3. MobileGuard also supports cryptographic keys from the device's internal keystore, ensuring that both the device and password serve as authentication factors.

Unlike traditional door readers, MobileGuard does not physically open doors or execute access transactions. Instead, it updates the cardholder's area field, timestamps the custom field, and optionally logs entries in the audit log. This approach aligns with its role as a mobile validation tool rather than a direct access control mechanism.

Additional Features

MobileGuard offers several practical features to enhance usability:

• Random Spot Check: Enables unbiased selection of cardholders for audits.
• Manual Relay Firing: Allows operators to manually open doors in cases of forgotten cards or emergencies.

In summary, MobileGuard is more than just an app—it’s a comprehensive tool for modernizing access control processes. Its portability, versatility, and robust security measures make it an indispensable asset for businesses, event organizers, and facilities looking to streamline operations and ensure safety. Whether you're managing daily access or responding to emergencies, MobileGuard puts the power of control in your hands.
