Barcode Technology - Interleaved 2of5 Barcode                      Hide the description

Interleaved 2 of 5 (also known as Code 25 Interleaved) is a continuous two-width barcode symbology encoding digits. It is used commercially on 135 film, for ITF-14 barcodes, and on cartons of some products, while the products inside are labeled with UPC or EAN.

Interleaved 2 of 5 is a special type of Code 25 that is also a numeric code able to display digits from 0 to 9. The code is also known as Code 2 of 5 Interleaved. It has no built in check digit. The advantage of Code 25 Interleaved is that the code uses self-checking and it is very compact so it does not need much space like the simple Code 25. Code 25 Interleaved is only valid if there is a even number of digits. To display an odd number of digits you have to add a zero to the beginning (123 becomes 0123) or you may use your own check digit..

Valid characters: 0123456789

Interleaved 2of5 is one of the many barcode formats currently in use.

A Barcode is a method of representing data in a visual, machine-readable form.

The barcode formats has two categories:

One-dimensional (1D) --- Barcodes represented data by varying the widths and spacings of parallel lines.

Two-dimensional (2D) --- Using rectangles, dots, hexagons and other geometric patterns to represented data.

Check digit:

No built in check digit.

Human Readable:

Most barcodes display their corresponding values below them, which makes it possible to human read and manually  enter the barcode values into the equivalent system when the barcode label is worn out and cannot be read by the barcode scanner.

The Advantages of using barcodes:

The bar code design and printing cost are low. Generally speaking, no matter how they are used or where they are posted, the cost is not high. They can be customized economically, in a variety of finishes and materials.

The barcode system is very versatile, it can be used for any necessary data collection. This may include pricing or inventory information or management information service system. In addition, because barcodes can be affixed to almost any surface, they can be used not only to track the product itself, but also to track the production process, shipments and equipments.

When barcodes are used in management information systems, they can promote better decision-making. Because data is obtained quickly and accurately, you can quickly obtain a full range of information for the entire company or organization, so it is possible to make more informed decisions. Better decisions can ultimately save time and money.

Barcodes are cheap and user-friendly, providing an indispensable tool for tracking data from pricing to inventory. The end result of a comprehensive bar code system is reduced overhead.

FAQ About Interleaved 2of5 Barcode

What is the historical origin of the Interleaved 2of5 barcode?

The Interleaved 2of5 barcode is a continuous two-width barcode symbol capable of encoding an even number of digits. Its predecessor, the standard or industrial 2of5 barcode, could only encode information in the width of the bar, not in intervals.

The Interleaved 2of5 barcode was invented by Intermec in the United States in 1972. It was widely used in the fields of warehousing and heavy industry in the early days, and was later also used in the field of transportation and packaging.

In 1987, Japan introduced the cross 25 barcode and standardized it for the identification and management of storage and transportation units. The EAN specification uses the interleaved 25 barcode as the standard barcode for storage and transportation units.

Is this encoding still used?

This encoding method is still used, but is not very common.

It is mainly used for 135 film, ITF-14 barcode, and some transport packaging cartons or wooden boxes, while the products inside the box use UPC or EAN barcodes.

What industries are Interleaved 2of5 barcodes mainly used in?

Interleaved 2of5 barcodes are mainly used in logistics, warehousing, transportation, medical and other industries.

Structural features of Interleaved 2of5 barcode

The Interleaved 2of5 barcode is a barcode symbology that can only encode numbers. It was developed on the basis of the standard 2of5 barcode to increase data capacity.

It consists of 5 barcode lines (3 black lines and 2 white lines). The barcode lines are only divided into thickness (thick is 1, thin is 0).

There are only 2 wide bars out of every 5 bars, and the width of the bars and intervals represent information.

Each barcode consists of two interleaved numbers, and each number is represented by 5 barcode lines.

It is necessary to add a start character and a terminator, as well as a check digit.

The number of digits in each barcode must be an even number, and "0" is added in front of the even digits.

In addition, Interleaved 2of5 barcodes often use protective frames to prevent misreading of data caused by incomplete scanning.

What is the difference between Interleaved 2of5 barcode and Code 128 barcode?

The Interleaved 2of5 barcode can only encode numbers, while the Code 128 barcode can encode 128 characters such as numbers, letters, and symbols.

The data length of the Interleaved 2of5 barcode must be an even number of digits, while the data length of the Code 128 barcode is not limited.

The coding rules of the Interleaved 2of5 barcode are to represent information based on the width of the bars and intervals, while the coding rules of the Code 128 barcode are to represent information based on three subsets A, B, and C.

What is the difference between Interleaved 2of5 barcode and EAN-13 barcode?

The Interleaved 2of5 barcode can encode information of any length, while the encoding length of the EAN-13 barcode is a fixed 13 bits.

The Interleaved 2of5 barcode is a universal barcode suitable for a variety of industries, while the EAN-13 barcode is a commodity barcode mainly used for the identification and management of goods.

What are the advantages and disadvantages of Interleaved 2of5 barcodes?

Advantage:

The data capacity is large, the encoding is simple, and information of any length can be encoded, as long as it is an even number of bits.

Suitable for logistics, warehousing, transportation, medical and other industries.

The Interleaved 2of5 barcode is a higher density barcode. Since both bars and spaces represent information and there is no barcode character interval, it is a continuous barcode. Because it can represent different numbers of numeric characters, it is a non-fixed length barcode.

Shortcoming:

Only numbers can be encoded, letters and symbols cannot be encoded.

Start and end characters need to be added.

Susceptible to contamination and damage.

Interleaved 2of5 barcodes are prone to misreading due to information loss. When the scanning path does not pass through two blank areas, it is easy to regard the bars and spaces of a barcode symbol as start characters or terminators, causing information loss or decoding errors. Therefore, Interleaved 2of5 barcodes are often used to identify fixed-length characters. At this time, the decoder or computer only receives fixed-length information. Short data information can be added with a "0" character at the beginning to achieve a fixed length.
