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 (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.
