True. Bar Reader scans a set of vertical bars of different width for specific data.
What about bar reader:
- A Bar Reader is indeed an optical scanner which can ’s acknowledged bars, interpret the data contained inside the bar, and transmit the information to a computer.
- It converts optical impulses in and out of electrical signals using a source of light, a lens, as well as a light sensor, much like a flatbed scanner.
- In addition, nearly all bar readers feature decrypter circuitry that really can analyse that bar image data created by the sensor and transfer the bar's information towards the scanner's output port.
