Computers allow banks to provide ATM services, online banking, speedier transactions and accurate tracking and verification of funds. They also make banking institutions more secure through enhanced security and surveillance setups.
Prior to computers, all bank accounting was done by hand. This meant that it would sometimes take several days for transactions to post to accounts, making it more difficult for customers to keep accurate track of their finances. Now, technology plays a significant role in the constant upgrade and addition of services available to help customers make the most of what their banks have to offer. Mobile banking services are also facilitated by computers.
