Authentication Methods

Authentication methods are used to securely verify users during locker access. They ensure that only authorized users can perform device pickup and drop-off actions and that all activities are traceable.

Each authentication method is linked to a user and recorded as part of the request workflow.

QR Code Authentication

QR code authentication is used during device pickup and drop-off requests.

Concept

• A unique QR code is generated for each request.
• QR codes are time-bound and request-specific.
• Prevents unauthorized or repeated access.

Workflow

NFC Card Authentication

NFC authentication allows users to access lockers using a registered NFC card.

Concept

• Each NFC card is uniquely mapped to a user.
• Authentication happens through physical proximity.
• No request QR code is required for identification.

Workflow

Authentication Usage in Requests

Authentication methods are used in combination with requests to:

• Validate user identity
• Control locker access
• Ensure traceability of device movement

Each completed action is linked to both the request and the authentication method used.
