It is possible to tell the module the product attribute code, which will hold actual EAN/UPC code.

In Magento store the EAN/UPC attribute should be Global Text type attribute.


Since Single product can have multiple EAN/UPC codes, then they are stored in a single text field.

Codes are separated by comma (,) and all whitespace between them is stripped.


This way when performing a search against single EAN/UPC code, then we can easily use MySQL FIND_IN_SET function to get results.
