A cashless society has its drawbacks
While I do agree with Peter Kammerer that cashless payments are more convenient (especially when change is involved), he does not mention the positive aspects of cash and the drawbacks of a cashless society ('Dying notes', March 6).
The biggest advantage of cash is the anonymity you have when buying items.
I can go to a bookshop or grocery store and purchase items with cash and they do not know who I am.
People who sign up for Octopus Rewards or money-back cards usually do not realise that they are receiving these rewards in exchange for their personal information.
Also, the buying habits of these people will be tracked for marketing use.
With cash, I do not have to worry about my personal information being used in such a way and possibly abused.
