For sure people will surely use digital transactions for a long time because of this pandemic but still there are some who will prefer to use physical cash because they don't have any digital cash.

This pandemic surely affected many people globally and the WHO said already that there is a chance that the virus will stay even though there is a cure being created soon. Although people are leaning towards digital transactions right now, I don't think that it will be like that permanently. There will be a time where people will go back to the normal transactions where they are using physical cash but it will take time for that to happen.
