It took some time but finally there are even more options to pay for your transit fare, at least for MRT Line 3 for now. Here is the graphic from the announcement by the DOTr:

Hopefully, these methods will be available to all rail lines including the PNR. Hopefully, too, these options will be available in buses and perhaps at least on modern jitneys. This will make it easier to pay public transport fares for the regular transit users.
