National Savings Certificates allow electronic purchase at CBS post offices and limit certificate transfer to a single occasion. Purchases of National Savings Certificates may be made by electronic mode at post offices operating on a Core Banking Solution platform. Transfer entries must record the previous holder and show the new holder under the dated signature, designation and date stamp of the authorized Postmaster. Transfer is permitted only once between issue and discharge. Rule 23 is omitted. The amendments take effect on publication in the Official Gazette.
