Many of your personal electronics have expandable memory options. One of the most convenient ways to boost the memory of your devices is to use an SD card. SD memory cards and micro SD cards are a form of compact flash memory that can easily be inserted into cell phones, digital cameras and more. Here are some common uses for SD cards for your own electronics.
Cell phones: Smartphones, music phones and PDA cell phones all store a lot of data. Typically, cell phones will have easily accessible SD card slots for expanding the memory. Read your phone's user manual to see which types of SD cards it can use.
Digital cameras: All those high-resolution photos take up a lot of storage space. A 10 megapixel DSLR camera, shooting raw images, can store over 300 photos on a 1-gigabyte SD card. You can fit more photos onto a single card by compressing the photos to a lower quality. Each camera uses cards with different speeds. The faster the card can write the photo data, the faster you can take photos in rapid succession.
Laptops: Many laptops have SD slots or SD card readers that allow you to transfer large amounts of data between devices. You can pull SD cards from your camera and cell phone and transfer the photos, music and contact data to your laptop, and vice versa. If your laptop doesn't have a built-in SD card reader, you can connect an external reader through a USB port.
Printers: You can print photos and other documents directly from SD cards if your printer has a memory card slot. You printer may only recognize a limited number of document and photo file types, so be sure to use compatible file types.
GPS navigation: Upload maps, firmware updates and other data to your GPS navigator with SD cards. Your GPS will also be able to store more map data with a memory card expansion.
