Reading Visa payWave Credit Card Details via NFC on Android

Tags:

Is it possible to read the credit card details (name, number, expiry) of a Visa payWave card via NFC on a Samsung Galaxy Nexus? What about other NFC-enabled credit cards?

If it's not possible, is there some way to retrieve a unique ID from the card?

Also, any references or example code would be a great help.
