Barcode font will not scan!

I am using your barcode fonts and they will not produce a scannable barcode. When I apply the font to my data, it looks like a barcode but does not scan. My barcodes are not reading! Help!!!

Unlike fonts such as Times New Roman, Arial, and Courier New, barcode fonts require an extra step to ensure that the created barcode is scannable/usable.

In order to create a scannable barcode, data must pass through something called a font encoder or font tool. The font tool will produce an output that may be in the form of start/stop characters, guard bars (for UPC and EAN), check digit, and encoded data. Start/Stop characters let the barcode scanner know when to begin and end a barcode scan. Check Digits ensure that the barcode is being properly created. Encoded data is data in the form that only barcode fonts can understand.

Imagine that you need to bake a cake for your cousin's birthday party.

You aka Barcode Creator

Think of the data as the cake mix, the font encoder or font tool as the spoon, bowl and oven, and the barcode font as the icing for the cake.

The Tool or Font Encoder

The cake mix (or data) must be mixed and baked (or passed through the tool or font encoder) using the tools and oven.

Once the cake has baked, it is similar to the encoded data. The last step to making a great cake is applying the icing (or barcode font).

Encoded Data

Scannable Barcode

This is basically how barcode fonts are used. The data is passed to an encoder tool, the data is encoded, and the barcode font is applied.

What is the purpose of a Font Encoder

Example: image

IDAutomation provides many FREE TOOLS that will allow you to encode data in several applications and environments including Excel, Crystal Reports, Access, FileMaker, Visual Studio, and Java.

If you are encoding your data with a font tool/font encoder and the barcode still does not scan, check the Top 5 Reasons a Barcode Font will not scan .

NOTE:

In order to create a valid Code 39 barcode, a font tool/encoder is not necessary as the asterisks (parentheses, exclamation points) can be placed at both ends of the data. For example:

*12345678*


2D Barcode Fonts include Encoders:
