How QR code will Make your Inventory Management System easy?

qr code for inventory management

Thinking of implementing an inventory control, it becomes difficult to decide and settle on a one-stop solution. Then, the QR code inventory management system is the solution you are searching for the control of your inventory.  

QR codes have become a well-known technology that is used worldwide to track inventories.

What is a QR code?

QR code is abbreviated for Quick Response code. It is a type of matrix or 2D barcode.  

Any barcode is a machine-readable optical label that contains all the information about the equipment to which it is attached.  

The QR code always contains data for locator, identifier, or tracker that points to a website or an application. The QR code includes vast information such as position marking, alignment marking, format information, and many more.  

A QR code consists of black squares arranged inside a square grid over a white background. This QR code can be read by imaging devices example camera. The code is processed using Reed-Solomon error correction until the image is properly translated. Then the required data is extracted from the horizontal and vertical patterns present on the image.

1st QR Code

The 1st QR was invented by an automotive Japanese Company Denso Wave in 1994.  

The main purpose of the designing of the QR code was the track of vehicles during the process of manufacturing. The QR code was designed to allow high-speed component scanning.  

Besides of commercial tracking application and convenience-oriented applications QR codes are also used to display text to the user, to add vCard, to open a URI, to connect to a wireless network, and to compose an email or text message.

Design of QR Code

Earlier, where 1D or linear barcode was designed to be mechanically scanned by a narrow beam of light now the QR codes are detected by the 2D digital image sensor and after gets digitally analyzed by a programmed processor.

Design of QR Code

The design of the QR code has three distinctive squares at the corners of the QR image. The processor locates these squares using the smaller square present near the fourth corner to normalize the size of the image, its orientation, and its view angle.  

Then the small dots present on the QR code image are converted to binary numbers and get it validated with an error-correcting algorithm.

Storage of QR Code

The QR code is meant to store the information about the locator, identifier, or tracker in the various forms of standardizing encoding modes such as:

  • Numeric (10 bits per 3 digits)
  • Alphanumeric (11 bits per 2 characters, can't store lowercase letters)
  • Binary (8 bits per character)
  • Kanji (13 bits per character)
Storage of QR Code

The data storage amount of the QR code symbol depends on the data type and error correction level. The information stored in QR codes includes positioning markings, alignment marking, time pattern, version barcode information, format information, keys for error and data correction, quiet zone, and more.

Maximum character storage capacity (40-L)

(Character refers to individual values of the input mode/datatype)

Encoding modes Max. characters Bits/Characters Possible characters, the default encoding Numeric only 7,089 3…“ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 Alphanumeric 4,296 5½ 0-9, A-Z (upper-case only), space, $, %, *, +, -, /, ., :. Binary/byte 2,953 8 ISO 8859-1 Kanji/kana 1,817 13 Shift JIS X 0208

Note: QR code has a minimum size also, it cannot be below 1cm * 1cm. The smaller QR code might not get read by the reader.

11 Advantages of QR Code Inventory Management System

From business cards to church bulletins QR codes are something that is popping everywhere. The QR code in itself has stored a huge amount of information that can be easily scanned and stored on a mobile phone.

QR code scanning process

QR code is an important tool for inventory management and manufacturing of inventories.

Some of the advantages of QR code inventory management system are as follows:

  1. QR code is used to track more than names and prices of products, this will include information as serial number, part number, lots and dates, and other data.
  2. The organization can move towards QR code when their barcode systems run out of capacity as the components which are used in QR code can exceed the limit of a maximum number of items as compared to a standard barcode.
  3. QR code inventory management is easier to handle and work with because the QR codes are typically easy to read through mobile phones and they don't require the bulky handheld scanners to read them.
  4. The QR code can be scanned from any direction with a wide-angle range of 360 degrees. This feature makes it easier for a device to read the QR code moreover reduces the chance of occurrence of issues with background interference.
  5. The QR code is made to store up to 100 times more information than a conventional horizontal barcode.
  6. Today most organizations are choosing QR codes standard barcodes as they can store URLs, geo coordinates, and texts.
  7. The QR codes are made to maintain the low-cost price as the organizations don't find any need to purchase scanners to record inventory transactions efficiently.
  8. The employees of warehouses and storage facilities nowadays prefer to use smartphones for scanning QR codes as they are more convenient and easy to use.
  9. There is no need for smartphones to be physically connected to the system or to be in close proximity to the system for inventory management operations in a warehouse.
  10. The QR codes have become a popular kind of barcode choice in supply chain operation as they can store more data information and lend themselves easily to scan via smartphone.
  11. QR codes can bridge different forms of marketing streams together. The organizations can save money by distributing QR code to their website or URL.

Note: The maximum storage capacities in QR codes occur for version 40 and error correction level L (low) which is denoted by 40-L.
