What is the ruling on working as an intermediary between companies, stores, and customers, where teams are formed to sell loyalty cards and a special application for the company, knowing that one of the companies being promoted sells alcohol?

Intermediating in thecribing of discount cards is impermissible due to the element of gharar (definition) (uncertainty/deception) and consuming wealth unlawfully. Therefore, it is not permissible to issue them, deal with them, or work for a company whose role involves attracting customers for such cards.
