Black Money Issue and Religion

In the present drive of cashless economy; some sections of the Muslim community have shown apprehensions to open bank accounts and use credit & debit cards on religious grounds. However, this argument is not valid and we refuse to buy this. It was observed that in most of the queues of exchanging of old notes at banks; there were so many Muslims. When Muslims had no issue in using banking for exchanging of notes; why they shall have reservations of using plastic money at the behest of religion.
