A barcode is an optical machine readable representation of data, which shows
certain data on certain products. There are different types of barcodes, some of them
have to be world wide unique and need license. We chose ‘‘code39’’ because first of
all, code39 doesnot need license, have the possibility to print for unlimited products,
supports full ASCII, number, letter and special character usage (capacity of 26
capital letters, 10 numbers, 7 special characters). And also it was the easiest to read
and was the best fit for the barcode generators for PHP. As the barcode generator,
we found one compatible with PHP. It is using PHP’s GD Graphics Library. We got
the script and modified it to be able to print serial barcodes. It prints barcodes in
increasing order (in multiple prints) on the screen, and sends to the printer. The
script is distributed under GNU License. And the hardware part of the system is out
of a label printer and a barcode scanner. Barcode scanner is a USB connected
model. It scans the barcode, writes to the field where the cursor is, and presses enter.
This function eases the usage.So the only extra hardware to be used by the staff will
be a barcode scanner after the system is implemented to the enterprise.
