Virtual NIN or vNIN is a 16 alphanumeric String that is to be used for security purposes instead of NIN, The string has a 72 hours lifespan
vNIN is a tokenised string that will not be useful after 72 hours after it has been created, thus limiting the risk of exposing the party involved to a long time risk
From now onward, you need not to give any body your NIN, rather you generate vNIN for them to verify, thus you are more secure
