This is just one reason why we need to resist, however we can, the banks' desire to do away with cash.
The banks tried to do away with cheques a couple of years back, and due to action by lobby groups and NGOs, the government stopped the banks from doing away with them.
There are many on low incomes who do not have a bank account, for many different reasons, and without cash they would find life much more difficult.
Closing branches, is easy if there are no cheques, this is no cash, and people are forced to bank online. The other nasty alternative is that all cash is electronic, people never check the online bank account and the banks can then do what they like. Doing things like changing interest rates downwards on savings accounts, and slipping in additional bank charges. Things they have done in the past. The savings made never seem to find their way back to the customer.
