Advantages
The advantages and limitations of numly barcode are same as that of any code 39 barcode symbology.
· Fast encoding and decoding because the data being encoded is only of the numeric type.
· No special scanning hardware is required and the barcode can be decoded using any simple scanner.
· Simple encoding and decoding algorithm makes it easier for a layman to understand and no extensive user training is required in this regard.
Limitations
· Low density barcode. As it can be seen from the image that in order to store large amount of data, the length of barcode has to be increased.
· Numeric only encoding. The barcode is not able to encode alphabets and special characters within its 19 digits.
· Extremely poor fault tolerance capability and damaged and distorted barcode cannot be decoded.
Usage
Primary user of numly barcode is the electronic and internet industry. It is used on software, websites, blogs, DVDs, books, PDFs and similar items in order to uniquely identify them.
