What is your laser visa number?
Your laser visa number is actually called a bar-coded number, it is read by laser. Bar codes are easy to identify, normally the numbers or numbers and characters will be below the bar code
Is a barcode scanner a input or output?
A bar code scanner is an input device. While it does contain a laser, the laser is used to read the data, not to communicate anything to the user. The bar code scanner reads the UPC codes into the cash register or point of sale system.

What does bar code scanner mean?
What a bar code reader is requires an understanding of the amount of information contained in the Bar code itself. Simply the amount of information is huge. All a reader will do is use a LASER beam to collect or read the bar code and transfer the information into a computer.
What is bar coding?
bar code, Universal Product Code (code consisting of a series of vertical bars of variable width that are scanned by a laser; printed on consumer product packages to identify the item for a computer that provides the price and registers inventory information)

Is it safe to use a bar code scanner?
Yes. A bar code scanner uses laser light. The light is of too low a power to burn skin, does not use frequencies that can penetrate skin. The only danger presented is to the eye if you stare into the light.
How are bar codes read?
Bar codes are read by a bar code reader. A low-powered laser in a bar code scanner emits a beam that crosses the bar code, generating a series of light and dark reflected flashes. These are read by the sensitive laser detector in the scanner and decoded to produce the numerical values shown on the label. These are compared to the codes in the store's computer to identify the item, look up the price, and add it to the register bill. Modern self-service check-outs have lasers that scan in two perpendicular directions, to read barcodes in any position relative to the scanner.
Where can one download a scanner bar code reader for the iPhone 5?
One can download a scanner bar code reader from the iPhone 5 from the Apple app store. There are many applications that can achieve this, some of them are: Scan Life, Scan - QR, Red Laser.
Bar code system- why must the number code be changed to binary for the laser readr to work?
Binary is the most primitive form of numeric notation and is by far the easiest to implement at the machine level.
How does a bar code laser scanner work?
A bar code laser scanner works by shining a bright light (laser light) at the barcode and measuring the reflected beam. In order to scan the entire barcode very quickly, the light is bounced off a spinning disk to cover the entire barcode in one pass.
