HID Mobile Access
HID Mobile Access is a solution that allows users to use their mobile devices, such as smartphones or wearables, as credentials for secure access to doors, gates, networks, and services. It leverages Seos® credential technology to enhance convenience, efficiency, and security. Key features include:
- Convenience: Access facilities with simple gestures like “Tap” or “Twist & Go.”
- Efficiency: Administrators can manage credentials through an online portal, issuing and revoking them via the cloud.
- Security: Powered by a secure cloud platform, it ensures reliable and touchless functionality.
Additionally, HID Mobile Access integrates seamlessly with Apple Wallet, enabling users to unlock doors and access systems using their iPhone or Apple Watch.
Apple Enhanced Contactless Polling (ECP)
Is a proprietary extension developed by Apple for the ISO/IEC 14443 (A/B) standard, which is commonly used in NFC (Near Field Communication) technology. ECP enhances the interaction between Apple devices and contactless readers by:
- Improving Privacy and Security: It ensures that Apple devices only communicate with readers when necessary, reducing the risk of unauthorized access or data interception.
- Optimizing User Experience: ECP enables seamless and efficient interactions, such as automatically selecting the correct pass or credential stored in Apple Wallet without requiring manual input.
- Supporting Advanced Features: It allows for the use of non-standard NFC passes and resolves conflicts when multiple passes share similar identifiers.
This technology is widely used in applications like transit systems, access control, and digital passes in Apple Wallet.
