yes you can use it. Camera is compatible with SD/SDHC, MMC/MMC Plus/HC MMC Plus cards so any of these cards will be ok.
yes
SanDisk is a brand of memory card. The Canon A540 takes a certain type of card, see its instrucvtion book, probably it's a CompactFlash, but it may be a SecureDigital (SD). Take the camera to a pghoto retsailer and get the right card - many cameras are fussy about just which manifestation of card they can accept. SanDisk will almost certainly make a card to suit your camera.
The Canon PowerShot A630 has a maximum resolution of 8.0 megapixels. The higher the resolution of a picture, the more space is taken up on the memory card.
Steps to opening the Canon Powershot: 1. Read the manual, insert battery and memory card. Be sure both the battery and memory card are of a compatible type as found in the manual. 2. Search the Basic Guide to find where the power button is located. 3. Press the power button to open the Powershot.
Assuming you mean the Canon Powershot A810 - It uses SDHC memory cards.
If it is a SD or SDHC card, then yes you can as I believe Kodak and Canon use them. The card typically has it's name on the front of it.
It just takes a regular SD memory card, but if you buy it at compUSA the memory card usuall comes with it, and if you want bigger mg you can just show the people at the place that you buy the card the one from the box.
Well in my answer the best memory brand is sandisk
only SanDisk SDMMC cards will fit
Use a SanDisk card reader
The Sandisk memory card is a microSD card often used in cameras and phones to store data. It is currently offered in 64 GB, 32 GB, 16 GB, and 8 GB options.
The SanDisk 8 GB MicroSD card has more than enough memory for a PSP, which only needs about 2 GB.
The SanDisk ImageMates are very good, but will have roughly the same build quality as other memory card readers.
