How do I get the TNB Jar?
Once you have spent a minimum of RM50 at TNB each month using Scan and Pay via the Boost app or the Boost Bank Debit Card, the TNB Jar will automatically appear on your Special Jars page when you log in to your Boost Bank account through the Boost app or the Boost Bank app. Simply deposit any amount into the Jar to begin earning the promotional daily interest.
