Do you know the difference between barcode labels and QR code labels?

Clothing barcode labels and QR code labels are two different encoding methods, and they are significantly different in many aspects. Here’s a detailed comparison of the two:

Definition and structure – barcode labels

Barcode labels:

Bar codes are one of the earliest automatic identification technologies that represent information by combining parallel lines of varying widths and spacing.

Bars and spaces primarily form a barcode, where bars represent the areas with lower reflectivity and spaces represent the areas with higher reflectivity.

One-dimensional barcodes can only represent information in a horizontal position and can usually only store limited data, such as about 20 letters or numbers.

QR code:

It is a matrix two-dimensional code symbol developed by the Japanese company Denso in 1994.

QR codes contain information both horizontally and vertically, and can store a large amount of data, such as numbers, letters, Chinese characters, photos, fingerprints, etc.

The QR code is square in shape, only in black and white, and has smaller square patterns (image-finding graphics) printed on three of the four corners to help the decoding software locate it.

Information Capacity

Barcode:

The information capacity is limited and can usually only store less information.

For example, the UPC code (the standard for supermarket retail industry) consists of 12 digits, including the country code, manufacturer number, product number and a check digit.

QR code:

The information capacity is large and can store up to thousands of characters or more information.

For example, QR code can encode up to 2509 numbers or 1520 alphanumeric characters.

Reading method – barcode labels

Barcode:

A special barcode reading device (such as a barcode scanner) is required for scanning.

The scanner needs to be aligned straight when scanning, and the scanning speed is relatively slow.

QR code:

Can be scanned using a mobile phone or other device with a camera.

No linear alignment is required when scanning, it can be scanned from any angle, and the reading speed is fast.

Application scenario

Barcode:

Mainly used for commodity settlement in retail industries such as supermarkets and shopping malls.

Also used in inventory management, logistics tracking and other scenarios.

QR code:

Widely used in product tracking, mobile financial payment, personal business cards, ticket management and other fields.

It can also be used to store website links, contact information, etc., so that users can quickly obtain relevant information.

Fault tolerance mechanism – barcode labels

Barcode: Usually there is no fault tolerance mechanism. Once the barcode is partially damaged, the information may not be read correctly.

QR code: It has a strong fault tolerance mechanism. Even if the barcode is partially damaged, the original information can be restored through the error correction algorithm.

When comparing the commonness of barcode labels (Barcode) and QR code labels (Quick Response Code), it is necessary to consider their respective application scenarios, technical characteristics and market demand.

Commonness

Commonness of barcodes

1. Retail industry: Barcodes are widely used in the retail industry, especially in the settlement of goods in supermarkets, shopping malls and other places. They are used to quickly identify and record product information and improve checkout efficiency.

2. Inventory management: Merchants also commonly use barcodes in inventory management to track the quantity, location, and status of goods while ensuring the accuracy of inventory data.

3. Logistics tracking: The logistics industry uses barcodes to track the transportation of packages and goods, ensuring their accurate and timely delivery to the final destination.

Common Use of QR Codes

1. Mobile Payment: QR codes are widely used in the field of mobile payment. Users can complete payment operations by scanning QR codes, which is convenient and fast.

2. Product Tracking: QR codes can be used for product tracking and anti-counterfeiting. Consumers can learn about product details, production date, origin, etc. by scanning QR codes.

3. Information Storage and Sharing: QR codes can store a large amount of information, such as website links, contact information, etc., which is convenient for users to quickly obtain and share information. In addition, QR codes can also be used in personal business cards, ticket management and other scenarios.

4. Marketing: Merchants can use QR codes for promotional activities, such as scanning codes for raffles, scanning codes for coupons, etc., to attract consumers’ attention and promote sales.

Comprehensive comparison

1. Application scenarios: Retailers, warehouse managers, and logistics providers primarily use barcodes to track products and inventory, while QR codes serve diverse functions in mobile payments, product tracing, information storage, and marketing.

2. Technical characteristics: Barcodes hold limited information and require scanners to align with them in a straight line. In contrast, QR codes offer large data capacity, support scanning from any angle, and provide faster reading speeds.

3. Market demand: With the popularization of smart phones and mobile Internet, the market demand for QR codes continues to increase, especially in mobile payment and information sharing. Although barcodes still maintain an important position in some fields, their application scenarios are relatively limited.

Obviously, although barcodes still maintain an important position in some fields, QR codes have become one of the more commonly used encoding methods due to their large information capacity, fast reading speed and wide application scenarios. Especially in mobile payment and information sharing, the application of QR codes has penetrated into people’s daily lives.
