Baba the story confuse me. You mean say scammers or hackers fit access POS though receipts? If this one na true na him bi say them go don hack almost all the PoS for Naija. Receipt na wetin almost all POS operators dey issue to almost all customers.
This thing wey you dey talk na true because I don see people dey drop withdraw slip anyhow but I never hear say one dey say them hack person account through this slip,I think op is trying to iron Something maybe him no know how to present am to us, because if you say this one na new tricks of scamming I go still doubt you because me never hear about such scamming strategy before.
and had it mean say this information na true by now in for don go viral because no be today pos work start. But e fit be say na true you dey talk sha, as you don pass the information like this we gats dey careful so that we no go fall for this kind of Scam.
