Could NFC scanning be added alongside QR codes, we currently use QR codes for security patrols and other inspections and NFC offers a significant improvement in efficiency, reliability, and security. The current QR system requires staff to scan QR codes at specific locations or on equipment to verify their presence, using a 32-digit hexadecimal identifier for security. However, this approach has several limitations. QR codes can be challenging to scan in low-light conditions, such as during night patrols, and they are prone to damage from environmental factors like dirt, moisture, or wear and tear. Additionally, the visible nature of QR codes exposes them to potential duplication or tampering, and the scanning process requires precise alignment, which can be time-consuming.
By replacing QR codes with NFC chips, these challenges can be addressed effectively. NFC chips allow staff to log their presence by simply tapping a device near the chip, eliminating the need for visibility or alignment. This makes the system ideal for low-light environments, as NFC functionality works seamlessly in darkness. NFC chips are also more durable, being encased in protective materials that resist damage from environmental factors, thereby reducing maintenance and replacement costs over time. Furthermore, the security of the system could be further enhanced by transitioning from a 32-digit hexadecimal identifier to 128-bit or 256-bit encryption, making it significantly harder to duplicate or tamper with the chips. Unlike QR codes, encrypted NFC chips do not display their data visibly, and the logic for displaying context-specific questions can be hidden within the software backend, further improving security and operational confidentiality.
While we currently start our inspection patrols by tapping a QR code to launch a template, some of our inspection contain 30 - 40 check points each with a QR code and our biggest employee frustration is scanning the Codes.
