Core Banking Systems & Computerised Accounting
(The Technology That Makes Modern Banking Possible — 24×7×365!)
From manual ledgers to Finacle, TCS BaNCS, and Flexcube — banking has gone FULLY digital. Core Banking Solutions (CBS) connect every branch to one central database. You deposit in Mumbai, withdraw in Delhi, check balance in Chennai — all in real-time. This chapter covers computerised accounting, CBS architecture, 6 components, advantages, disadvantages, CRM, omni-channel, and neo-banking.
Banky’s Final Chapter — The Tech That Powers Everything! 💻🏆
Every transaction Banky has processed — deposits, withdrawals, loans, DDs — goes through the CBS. It’s the BRAIN of the bank. Without it, there’s no internet banking, no ATM, no NEFT, no UPI. This final chapter brings everything together — how technology transformed banking from pen-and-paper to 24×7×365 digital service.
The Full Chapter — Technology Meets Banking
💻 Part 1 — Computerised Accounting: Basics
What is it? Using computers to perform accounting functions: capture transactions, prepare financial statements, generate reports. Computer = hardware (physical) + software (instructions/programs).
5 Features: (1) Speed — 1,000 invoices processed in minutes. (2) Accuracy — no human calculation errors; trial balance ready in seconds. (3) Various Reports — area-wise sales, age-wise analysis, all from same data. (4) Economy — cheaper than human labour in the long run. (5) Reliability — consistent output, no mood swings!
5 Disadvantages: (1) Special programs + programmers needed (costly initially). (2) Qualified staff required for operations. (3) Costly peripherals and stationery. (4) Regular BACKUP required (data loss risk). (5) Computer VIRUSES can destroy data.
NOT a disadvantage: “Secrecy of customers’ transactions is lost” — this is WRONG! Computerised systems actually IMPROVE security and secrecy. Exam trap!
Types of computers: Digital (used in accounting), Analogue (scientific), Hybrid (combination). Mostly DIGITAL computers used.
Popular accounting software: Tally ERP9, CBS (Finacle, TCS BaNCS, Flexcube), SAP, Oracle, QuickBooks.
🏦 Part 2 — Core Banking Solutions (CBS)
What is CBS? A centralised system where ALL branches are connected to ONE central database (data centre/hub). Every transaction at any branch is recorded in real-time at the central server. This enables “anywhere, anytime, 24×7×365” banking.
Architecture: Powerful server at central data centre (HUB) → each branch has a branch server → each user has a terminal → terminals connect to branch server → branch servers connect to central hub via dedicated lines.
Old system (decentralised): Each branch had its own server, database, applications. Problems: high cost, no coordination, difficult updates, no real-time inter-branch transactions. New system (centralised): One data centre, unified IP network (data + voice + video on same network), real-time updates, lower costs, better control.
6 CBS Components: (1) Financial Institution Infrastructure, (2) Product Build, (3) Customer Management & Overview, (4) Account Administration, (5) Payments, (6) Management Information.
9 Banking operations now on CBS: Deposits, Lending, Remittances (RTGS/NEFT/IMPS), Clearing (CTS), Standing Instructions, ATMs, Centralised Banking (“any branch” banking), E-Banking (internet/mobile), Safe Deposits.
🌐 Part 3 — CRM, Omni-Channel & Neo-Banking
CRM (Customer Relationship Management): Technology + strategy to know your customer better. How many customers left? What services do they use? Who are the profitable customers? CRM helps banks retain customers and cross-sell products (insurance, RBI bonds, credit cards). Key question: “How well do you know your customer?”
Omni-Channel Banking: SAME services across ALL channels — website, mobile app, branch, call centre, WhatsApp, Facebook, Instagram. Data synchronised in REAL-TIME. Start onboarding on one channel, finish on another. No repeating information!
Neo-Banking: Bank with NO physical branches — entirely online! Simple account opening, lower costs, user-friendly interface. Appealing to tech-savvy customers who manage money through phones/tablets.
Information Security: Change password at least ONCE A MONTH. Never share password. Don’t allow anyone to use your computer. Regular backup essential.
