I have opened my account in sbi because of its highly secure technology. account information never gets leaked to other person. also they have so many branches in india. they take less interest on home loans, vehicle loans etc compared to other banks. the staff of sbi is very polite and give information properly when asked. sbi has also opened internet banking, so every one can access their account seating at your home and you can also do online shopping by its net banking facility. it is the most reliable bank.
