What is a Memory Stick PRO Duo?

A compact flash memory card that can expand the memory of compatible electronic devices to store more games, data, photos and more. Common devices that use this memory are cameras, phones and some handheld game consoles.

Is this the same as other Memory Stick-brand cards, like Duo or Micro?

Due and Micro are in the same family of storage devices, but they use a different form factor and may not be compatible with Memory Stick PRO Duo devices.

I have Memory Stick Duo and Memory Stick Micro cards that won't fit in my new devices. Is there any way to continue to use them?

Walmart has you covered. We sell Memory Stick adapters that allow you to use those cards with Memory Stick PRO Duo devices.
