How does a barcode reader read barcode?
A barcode reader (or barcode scanner) is an electronic device for reading printed barcodes. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating optical impulses into electrical ones. Additionally, nearly all barcode readers contain decoder circuitry analyzing the barcode's image data provided by the sensor and sending the barcode's content to the scanner's output port.
Can you use neo reader to read bar code in mobile?
In general yes. The issue is that some mobile phones don't have a good enough camera, and therefore won't be able to focus on the bar-code. Try using it with mobiles that have auto focus.

The purpose of a barcode is to encode information in a machine-readable format, allowing for efficient tracking and management of products. It enables quick data entry and retrieval, streamlining processes such as inventory management, point-of-sale transactions, and shipping. Barcodes help reduce human error and improve accuracy in data handling, ultimately enhancing operational efficiency across various industries.
What kind of bar code do retail and grocery stores use?
The most common bar coding symbolinguism is UPC, EAN, code 128, and code 39. Most widely used among grocers is UPC because it is more easily adaptable to register terminals and pricing programs.

A bar code is a product descriptor code created to be read by a computerised scanner or EPOS machine ( a till). It consists of 11 numbers in groups of "0"s, the black strips and "1"s are the white strips. Tis is the format computers use - BINARY. A
The first number describes the type of product. Most products begin with a "0"; exceptions are variable weight products such as meat, cheese and vegetables (2), health-care products (3), bulk-discounted goods (4), and coupons (5).
The number 1 is never used as the scanner (a laser) could mistake it for a black bar - a 0
The next five numbers are the product's manufacturer. These are registered internationally to make the manufacture code unique. The next five numbers after that describe the product itself, including its color, weight, size, and other distinguishing characteristics. The code does not include the price of the item or any taxes to be added. When the identifying code is read, the information is sent to the store's computer database, this is frequesntly called the back office system, which checks it against a price list and returns the price to the cash register.
The last number is a check digit, which tells the scanner if there is an error in the other numbers. The preceding numbers, when added, multiplied, and subtracted in a certain way will equal this number. If they do not, a mistake exists somewhere.
Complicted at first but once you look at the codes on your food you will soon understand.
You will also see a in many codes now that they have become 14 charectors. This is because a 3 digit code as been added to the existing product information . GS1 Prefixes do not provide identification of country of origin for a given product. They simply provide number capacity to different countries for assignment from that location to companies who apply. Those companies in turn may manufacture products anywhere in the world.
lines on a bar code are almost like encrypted files, they can only be read or detected through a special device. This allows a computer (cash register) to acknowledge an item and decodes the price.
Where do people use bar codes?
Many places, but very often in stores and warehouses that have a large number of different products to keep track of, like a grocery or department store.
The motivation is to save time and money, it is quicker and less error prone to scan in a bar code than to type in the name of a product, or even to select one type of cereal from a list of a dozen others.
