With this kind news the poor no go still breath, e no suppose be necessary if you dey fill up bank form, such space should be marked as "Not necessary" cos almost 80% of Nigerian are not using mobile phone, those wey get phone sef no even get social media handle, only WhatsApp and Facebook. To me this is waste of time and inappropriate to use know your customers, a simple NIN code is enough because that suppose contain all information the bank need, that's all.
