According to an Email from Google:
Your Wallet Card will only work until June 30
Hello (user)
Thanks for ordering a Wallet Card.
After careful consideration, we’ve decided that we’ll no longer support the Wallet Card as of June 30. Moving forward, we want to focus on making it easier than ever to send and receive money with the Google Wallet app.
Here’s what this means for you:
You can still activate your card, but you’ll only be able to make purchases with it until June 30.
You won’t be able to add money to your Wallet Balance from a debit card or bank account after May 1, but money you receive from others will still be added to your balance.
If you have money in your Wallet Balance after May 1, you can keep it there, send it to others, or cash out anytime for free.
As we wind down support for the Wallet Card, we’re excited to continue enhancing Google Wallet to give you the best possible experience when paying friends and family. We’re hard at work on new features, so keep an eye out for those in the coming months.

This will leave a certain number of people scrambling for a better solution.
The Google Wallet card, (basically a standard Debit Master Card) was very convenient for funding kids at College, or sending money to family/friends. Money in the wallet could be spent with the debit card.
Apparently the Wallet will continue to work, but transferring money out of wallet to anything but the Google Play store will become impossible. There are vague promises in the FAQ about future enhancements, but nothing concrete.
Another Google service killed by its own popularity.
