This feature is available with the Green Dot Visa® Debit Card and Pay As You Go Visa® Debit Card. The Money Vault is a FREE feature that allows you to set aside cash for a rainy day or a specific goal. Use it to stash cash for safe keeping, emergencies, or future purchases. Money in your Vault cannot be spent on purchases or cash withdrawals. You can move funds in and out of your Vault as often as you like, subject to security limits. There are no additional fees to use the Vault, but money in your Vault does not earn interest.
