4. The first-ever image scanner to be compatible with a computer developed in 1957. It was a drum scanner that uses photomultiplier tubes instead of the charge-coupled device.

5. A flatbed scanner is also called a reflective scanner. It is due to its working by shining white light scanned-object, analysing the intensity and colour of light reflected from the object.

6. Nowadays, Iris Scanners are very essential for high-security spaces as the risk of manipulating them is very minute, compared to other security devices.

7. It is believed that it is better to scan the negative (film) rather than the actual picture. The negative film provides a better colour resolution to work rather than a print.
