Answer:
A biometric device is a security identification and authentication device. Such devices use automated methods of verifying or recognising the identity of a living person based on a physiological or behavioral characteristic. These characteristics include fingerprints, facial images, iris and voice recognition.
A Quick Response code, or QR code, is the next generation of barcodes. Those little jumbled squares were originally designed to track cars through the manufacturing process, but today, quick response codes can be found everywhere from assembly lines to warehouses and on everything from business cards to billboards.
