BITS ‘N’ PIECES
Narrated by Abu Musa Al-Ash’ari (R.A)
Allah’s Apostle (S.A.W) said, “The example of a believer who recites the Quran, is that of a citron which smells good and tastes good; And the example of a believer who does not recite the Quran, is that of a date which has no smell but tastes sweet; and the example of a hypocrite who recites the Quran, is that of an aromatic plant which smells good but tastes bitter; and the example of a hypocrite who does not recite the Quran, is that of a colocynth plant which has no smell and is bitter in taste.”
Sahih Bukhari, Volume 7, Book 65, Number 338
Barcodes and scanners streamline transactions and simplify goods tracking across industries.
Barcodes are machine-readable representations of data that consist of a series of black and white lines or patterns. They are widely used for tracking and identifying products in retail, inventory management, and logistics. A barcode encodes information such as a product's price, manufacturer, and unique identification number, allowing for quick and efficient processing in various industries.
There are two main types of barcodes. One-dimensional (1D) barcodes are the traditional barcodes found on most consumer products. They consist of parallel lines of varying thickness that store data, with common examples including Universal Product Code (UPC) and Code 128. Two-dimensional (2D) barcodes, on the other hand, store more information and can include text, website links, and images. These use squares, dots, or hexagons instead of just lines, and examples include QR codes and Data Matrix codes.
Barcode scanners are devices designed to read and interpret barcode data. They use different technologies to capture and decode the information, which is then transmitted to a computer or point-of-sale system. When a barcode scanner is directed at a barcode, it emits a light source, usually a laser, LED, or infrared light. This light is reflected back to the scanner, with the black bars absorbing light and the white spaces reflecting it. A sensor inside the scanner detects the reflected light and converts it into an electrical signal. The scanner measures the intensity and pattern of the reflected light to differentiate between the bars and spaces. The electrical signal is then processed by a decoder, which translates the barcode pattern into alphanumeric characters. This information is sent to a connected device, such as a computer or cash register, where it is displayed or stored.
There are several types of barcode scanners, each designed for specific uses. Laser scanners use a laser beam to read the barcode by scanning across it in a straight line and are commonly found in retail stores. Charge-Coupled Device (CCD) scanners use LED lights and small sensors to capture the barcode image. Imaging scanners function like digital cameras, capturing a full image of the barcode before processing it. Handheld and wireless scanners are also widely used in warehouses and logistics for mobile scanning.
Barcodes and barcode scanners have revolutionized inventory management and retail operations by improving efficiency and reducing errors. Their ability to quickly process information has made them essential tools in modern businesses, streamlining transactions and simplifying the tracking of goods across different industries.
