Categorization of QR Codes for Collecting Data

QR codes can serve several functions. Due to their wide variety of uses, QR codes can be divided into four main categories. 

Each of these variants of a QR code is an “input mode” that contributes to the determination of data storage options. These systems may be referred to as numbers, alphabets, binary digits, or Japanese kanji characters. Any QR code’s associated version information conveys this mode.

Numeric Code

Numeric codes are made up of decimal digits combining numbers from 0 to 9. Numeric code remains the most effective storage mode. It has almost 7,089 characters available in its chamber. 

Alpha-Numeric Mode

This is a decimal digital number case combining 0 to 9. The alpha-Numeric mode also combines uppercase letters from A to Z using symbols such as $, %, *, +, -, ., / and spaces as well. It combines almost 4296 characters in store.

Byte Mode

This is for characters from ISO-8859-1 types of characters. It uses 2953 characters that can be stored.

Kanji Mode 

This is a double-byte character from the Shift JIS set of characters previously used to encode Japanese characters. In addition to being out of date, this device only has space for roughly 1817 characters. The second Kanji Mode, extended channel interpretation, allows you to use the UTF-8 character set for kanji.

The Functionality of QR Codes

The majority of smartphones in today’s time can scan a QR code using their cameras without taking the help of an app. Scannable QR codes follow the following user journey:

  • They are redirected to a web page containing a series of questions. 
  • They answer the questions one by one and tap done.

The information gathered through these QR codes, or contactless forms, are stored in a highly secure cloud. With the permission grant, any user can access this cloud from any part of the world. 

Contactless forms remain the greatest mean in post-COVID times for digital transformation projects.

What is the Conducive Environment for Using QR Code for Data Collection?

There is only one classical criterion based on which a QR code can be used— the unavailability of pen and paper. The QR code is the most efficient to be used in an environment that demands a contactless transaction of data movement. Data can still be collected classically through the following channels.
