KYC tiers are account levels set by the identification and due diligence information a customer provides. The tier a customer holds determines the transaction limits on their account and card, from N30,000 a day at Tier 1 up to N2,000,000 on POS and web at Tier 3.
Know Your Customer information is collected on account opening forms together with permitted identification documents, at least during the onboarding stage.
Card and transaction limits by tier are published in the card limits record.
