We all use our iPads to watch movies, play games, and even take pictures. iPad 2 does not accept SD or other types of cards. You can’t connect your USB flash drives to your device either. These 5 card readers and adapters allow you to get even more out of your tablet:
iPad Camera Connection Kit: if you plan to connect your camera to your iPad or move your pictures from it to your tablet, this kit can help.
CF Card Reader Compact Flash Card Adapter: lets you connect your compact flash card to your iPad. It is very compact and quite portable.
5 in 1 Camera Connection Kit for iPad: similar to the first item but can also handle MicroSD cards and MiniUSB connections.
Protech 4in1 USB Camera Connection Kit: another compact card adapter for iPad that can handle SD(HC), M2, TF (T-Flash) memory cards.
Square Credit Card Reader: not your classic card reader by any means. This add-on lets you read credit cards on your iPhone or iPad. Useful tool for businesses.
The above add-ons are compact and make it possible to read all kinds of cards (memory or credit card) on your iPad. They don’t cost a whole lot which is always nice to see.
