What patterns are used in barcodes?
Later, two-dimensional (2D) variants were developed, using rectangles, dots, hexagons and other patterns, called matrix codes or 2D barcodes, although they do not use bars as such. 2D barcodes can be read using purpose-built 2D optical scanners, which exist in a few different forms.
How and why barcodes are used in medicine identification?
Bar codes and bar-code readers are great tools for verifying information about a drug before it is dispensed or administered to a patient. In order to work most effectively, each individual dose must have a unique bar code on its packaging identifying the drug and the amount of the dose.

Do medicines have barcode?
The medication barcode ensures to avoid human error and administer accurate medication to a patient at the right time. All drugs present in the hospitals and pharmacies are labeled with unique barcodes generated by the BCMA system.
Does barcode scanning reduce medication errors?
The results of the analysis showed that the pooled effect size of studies was equal to OR=0.426 (95% CI: 0.273–0.653), It indicated that wristband bar-code medication scanning can reduce some MEs about to 57.4% in the hospital.
Why is a barcode important?
Across many industries, barcodes offer automatic product identification, extremely fast recognition and implementation of data. ( Barcodes save time.) Barcodes provide asset & security tracking, theft deterrence, peace of mind, and a demonstrable reduction in loss/liability. ( Barcodes reduce liability.)
Is QR code better than barcode?
A QR code can carry up to some hundred times the amount of information a conventional barcode is capable of. When comparing the display of both: a conventional barcode can take up to ten times the amount of printing space as a QR code carrying the same amount of information.
What is barcode and its types?
One-dimensional (or 1D) barcodes systematically represent data by varying the widths and spacings of parallel lines. These include some of the most traditional and well-recognized barcode types, such as the UPC and EAN codes. 1D barcodes are also commonly referred to as linear barcodes.
What information is contained in a barcode?
Barcode contains information about a product like; price & weight of the product, date of manufacturing and expiry, name of the manufacturer etc. Barcode is allocated by an international institution set up for this purpose. Every product has a unique barcode all over the world.
