One Nigerian fintech, Flex, is tackling digital fraud by replacing account numbers with paytags—unique identifiers that let users send and receive money without revealing personal banking details. Founder Chika Okere said the idea came after he shared his account number with a parking attendant and later discovered the attendant knew his middle name, which he does not use publicly. This experience highlighted how easily personal information linked to account numbers can be misused. In Nigeria's current payment system, sharing an account number often exposes a person's full name, bank, and behavioural patterns, creating opportunities for fraudsters to gather fragments of data over time. According to Okere, fraud typically begins not with a single large breach but through the gradual collection of small pieces of information like phone numbers, account details, or leaked BVNs. Flex's paytag system aims to create a barrier between identity and transactions by allowing payments through pseudonyms. While similar systems exist globally and have been attempted in Nigeria before, Flex is building this within one of the world's most fraud-prone financial environments. The company emphasized that its goal is not to replace the banking system but to mask sensitive information during transactions. For example, a user could send money from an OPay wallet to a Zenith Bank account without either party seeing the other's account number. The system operates as a closed loop, handling settlements in the background while keeping personal details hidden. Flex also disclosed it deliberately slowed its growth to finalise licensing partnerships related to microfinance banking, mobile money operations, and payment service solutions.
Flex positions paytags as a privacy shield, yet it relies on the same account-linked infrastructure it claims exposes users. If a paytag can be traced back to a name and bank through existing systems, the core vulnerability remains unchanged. The company's decision to slow growth for licensing deals suggests regulatory compliance is a bigger bottleneck than technological innovation. For Nigerian users, this means fraud prevention may depend less on new features and more on how tightly those features are insulated from legacy data leaks.
