This digital camera supports an SD|SDHC|SDXC memory card, which is typical of many similar spec digital cameras that are a comparable age to it. SD cards are by far the most common type of memory card. They are compatible with the majority of digital cameras.
It may also be worth also looking at one of the other cameras that support an SD|SDHC|SDXC memory currently available including the Coolpix S6500, or the Coolpix L120 ($299.50) both from Nikon or the Canon PowerShot SX600 HS ($199.00) which has better reviews.
