Though I'm no longer with YEHEY! nor PAYplus+, I still feel obliged to respond to this.
The service was shut down by Bancnet due to some uncertainties with THEIR security. They had PAYplus+, a proprietary system of YEHEY! improved on some security features however the said uncertainties or loopholes were never addressed internally by Bancnet due to the fact that we have a rushed and a very vague e-commerce law in the country. As for Megalink, I don't have an idea now, but they were just cautious as well. Sayang talaga yung technology, and we WERE the first to develop and launch an online debit system pa naman.
Right now i dont know what's going on with YEHEY!/PAYplus+, but one thing is for sure... this is/was a legitimate WORLD-CLASS system.
if you have questions email them nalang
