Welcome to the Pamantasan Ng Cabuyao (PNC) Secure Document on-line authentication service, where secure documents could be validated by scanning their 2D symbols (or manually entering the SEK values of the symbols) and when necessary by clicking the above email address, requesting with the PNC secretariat's office further details or a digital image of this secure document.
Barcode scanning the 2D symbol on the document automatically places the symbol's SEK value into the validation field. If the SEK is valid, an appropriate VALID message will display.
Using an Internet connected smart phone or tablet may require one or two more steps to validate the 2D
Otherwise, the validate button will return either an "SEK not entered" or "Invalid" message.   In the absence of a 2D barcode scanner, manually key in the human readable 21 character SEK exposed by an inexpensive, portable UV or blacklight source, then press the Validate button.
