If you have already enlisted the Std Charted Bank A/C holder, then you can try through NEFT or RTGS mode of payment. NEFT takes 3-5 hours, on a working day. If you effect a transaction on a holiday, then it will get credited on the next working day. For RTGS, the minimum amount would be in lakhs. for smaller amount, try NEFT. Inter-bank transaction are routed through RBI, so instant credit is not possible, but takes a few hours. If transaction is within the same bank, then it will get credited instantly.
