Which evolved variant of the QR code is designed with an encrypted data segment for high-security access control?
Answer
Secure QR Code (SQRC)
For environments demanding heightened security and privacy, such as high-security access control, Denso Wave developed the Secure QR Code (SQRC). This variant incorporates an encrypted segment of data that can only be accessed and read by using a dedicated, authorized scanner. This mechanism ensures that sensitive information, such as an employee's photograph which can be cross-referenced offline against a live camera feed, remains protected from unauthorized scanning or replication inherent in the basic, openly known ISO-standardized version.
