Hi,
I have seen this kind of situations where information is not fully stored in the systems, having said that, my approach is to double check data integrity in the system while scanning. I am experienced on low and high level programming, from programming hardware to web sites. I have experience on C/C++, PHP, JavaScript, MySQL and ZPL, which is a native language to program Zebra printers and create custom labels.
Please be open to contact me for furthermore questions on my experience.
Best regards.
