To curb or reduce and illegal banking transaction in Nigerian banking system, Central Bank of Nigeria (CBN) in 2015 directed all account holders home and abroad to enrol for a bank verification number also known as BVN.
BVN is an 11 digit identification number that gives every Nigerian with a bank account a unique identity that can be verified across the banking industry in Nigeria. This means even if you have accounts with all banks in Nigeria, you only need one BVN and you can link it to all other accounts.
This article will explain all you need to know about BVN and biometric, different ways to link BVN to your GTBank account and how to retrieve your unique number if forgotten by USSD or short code using phone and number (MTN, ETISALAT AND AIRTEL) associated with your bank account.
Bank verification number is a centralized biometric identification system launched by CBN in collaboration with all Nigerian banks to curb theft. Before we continue to top things you need to know about BVN, I will like to digress a little and explain the working principle of biometric.
Working Principle of Biometric
Biometric devices uses a reader or scanning device to scanned human biological data/characteristics like fingerprint, voice, facial features etc.., a software that coverts the scanned information into digital form & compares match points and a database that stores the biometric data for comparison. This data are usually encrypted to prevent identity theft.
To convert the biometric data, the software identifies specific points of data as match points. The match points in the database are processed using an algorithm that translates that information into a numeric value. The data set value is then compare with the Biometric the end user has entered into the scanner and authentication is either approved/granted or denied.
The working principle of biometric remains the same, no matter what methodology is employed. That is, a record of human’s unique biological data that is captured and kept in database and when verification is required, a new record is captured and compared with the previous one in the database. If it matches, it confirms the identity. It is a more secure means of identification or authorization to password.
