2. 1. A QR code has two dimensions that can support
different kinds of data.
2. Numeric data, alphanumeric characters, and Kanji are
the three main data types.
3. The components of the QR code include indicators
and data code.
3. What is a QR code?
Quick Response code
A QR code is a type of two-dimensional matrix barcode, invented in
1994, by Japanese company Denso Wave for labelling automobile
parts.Quick response (QR) codes are square-shaped matrices of dark or
light pixels used to encode and quickly retrieve data using computer
devices.
4. Some of the most common types of QR Codes include:
• URL QR Code. • Image gallery QR Code.
• PDF QR Code. • Google Maps QR Code.
A QR code consists of black squares arranged in a square grid on a white background, including
some fiducial markers, which can be read by an imaging device, such as a camera, and processed
using Reed–Solomon error correction until the image can be appropriately interpreted.
Reed–Solomon codes are a group of error-correcting codes
5. In Medical science
Now , we got an idea of implementing these QR code in medical
science
• Demonstration of tablets , and other prescription for regular
medication can be done using generating codes
• Whenever wherever and by whoever can utilise these prescription
via QR code
6. In Airports
• In the tickets of cancellation of a person , some other would
be benefited.
• The unknown tickets of cancellation can be easily shown to
person of requirement.
7. 1. Any person with a smartphone can get access to information
stored in code.
2. In India, not every person is familiar with the use of a QR-Code
on billboard or pamphlets.
If this implements ,
• Many people in India would get benefitted
• Mainly mediation time gets easier
• There will maximum no wastage of tickets in planes
8. • They are safe
• They are quick
• They hold more data
• They direct customers straight
away
• They increase engagement
