There have been a few recent changes to Google Wallet. First is that Google Prepaid Cards are now gone. This is a card that you can load money into from a debit or credit card. You can think of it as a way to control your spending or for security in the event that your phone was compromised. Thieves would only be able to steal the small amount you loaded onto your Google Card.
The second change is the ability to add any credit or debit card to your google account. Before this, it was only able to accept a Citi card. This makes for a more convenient way to use the cards you most frequently use.
