Guides
Guides to Nigerian bank transaction data
A Nigerian bank statement is mostly free text. These guides tell you how to read it: who a transfer names, what each charge is, and which payments repeat.
Each example is invented, and no name, account or reference on these pages belongs to anybody. A test runs each example through the engine and fails if a page and the engine disagree.
