Once activated, every time you spend on your Hugosave Card, Hugosave rounds up your purchase to the nearest dollar (which is deducted from your Hugosave Save Account) after the merchant has settled the transaction. The roundups then places the excess into your Roundups ledger.
Each week the accumulated Roundups are swept into your Hugosave vaults (Every Wednesday by the end of the day) and automatically invested into physical gold.
