David Bismark devised a practical solution for a safer and more secure electronic voting. I think this is worthy of consideration even in the Philippines. The ballot paper is not as complicated as the PCOS papers look and most importantly everyone can individually check online whether their counts were added or not without revealing the actual votes. No one can mess with your votes simply because the order of candidates differ from one ballot to another. It does not look expensive either. This is simply election magic! Here is his TEDTalk.
