Digital SLR: Digital camera accessories Digital camera memory card reader
A memory card reader, attached to your computer, is a better way of transferring photos from camera to computer than linking the two with a USB cable. It's quicker and saves camera battery life. Memory card readers are cheap, around £5 upwards.
Multi-card readers are also available. These can read many different types of card – useful if you have several cameras or electronic devices that use different types of memory cards. Most can read standard Secure Digital (SD) and high capacity (SDHC), Compact Flash (CF), Memory Stick (MS) and xD cards.
To see which camera brands and models are compatible with which types of memory card, see our digital camera and digital SLR reviews.
Use the interactive media card capacity calculator to see how many photos, MP3 files or videos you can fit on a memory card.
