How would this work for being a mystery shopper, that the company says I need a credit card to get assignment's?

Sorry, but could you explain in detail what your query is so that we could assist you accordingly?

When I received a message on LinkedIn about being a mystery shopper, when I opened the message it also brought me to jotform. The company can't assign me to any assignments because I don't have a credit card only my bank card. Would this work as if I had a credit card? 

I presume your concern is related to a form that you have received via Linkedin. The form was created by someone using JotForm and hence your query to us.

The form should be containing some payment field which requires you to pay either via credit card or any other mode. Generally, the online payment processors accept debit card also as long as they bear the supported logo like Visa, MasterCard, American Express, etc.

Could you share the form with us so that we could check which payment processor is linked to the form?
