The technical glitch that affected DBS and POSB on Monday shows how much most of us have become reliant on banking services.
Since technology can never be 100% failsafe, it makes sense that we are able to access more than one bank for our banking needs.
Personally, I also hold a UOB atm card as I find it so much more convenient. While the reach is not as extensive as POSB atms, they can be found in most central areas like MRT stations and shopping centers. And most of the time, the queue (if they is any) is shorter.
Of course, if you are going to have multiple bank savings accounts, make sure your average balance does not fall below the stipulate amount in order not to incur any necessary fees.
