Ramesh Naidu, a 35-year-old businessman from Hyderabad, opened a current account with Indian Overseas Bank in August 2025. He receives regular payments from clients, often amounting to ₹1,00,000 per week. Tired of visiting the branch to check balances and make transfers, he decided to activate the Indian Overseas Bank net banking. 

Using his 15-digit account number, mobile number, and debit card, he completed the self-registration process online in 15 minutes. After OTP verification, his login ID was created successfully. However, since fund transfer was disabled initially, he later enabled it through the “Edit Profile” tab and set a ₹2,00,000 daily limit.
