Hi,
I've a plan of how this can be implemented, and unless you've a specific scheme in mind, I'll prefer to use PHP to generate a PNG of the pictorial barcode. Same script can also implement decode functionality for an uploaded PNG file.
I have MSc in computer science, over 15 years of experience, and I'm a published author of books on Data Structures & Algorithms, Programming in C++, and Java Programming. I routinely help graduate/post-gradate students, and even doctoral candidates with various tools & utilities required in their academic pursuits of top grades, coded in C/C++/Java/Python/PHP.
I believe in first time right delivery, and this commitment is reflected in my 5-star rating and 100% completion rate.
Looking forward to working with you on this project, and establishing a basis for ongoing professional engagement.
Thanks,
Gaurav
