Is working for an information security services company that specializes in securing insurance card data (Visa, MasterCard) for banks permissible or forbidden, and is it permissible to help one's father with the expenses of Hajj from this money?

It is permissible to benefit from the wages of work or from a father's assistance for Hajj or other matters, as long as the work is not predominantly used for unlawful purposes. However, working for an interest-based bank or an institution whose transactions are mostly unlawful is not permissible.
