When i insert sd card it say not supported card

Question edited for clarity.

This is always because people buy modern SD Cards that are far too bit for older cameras. The maximum size for an SD Card is 2GB. Also you must format the card inside the camera.

Look in Settings/Storage/SD Card and see if you have a Mount option when you insert the card. Make sure the card has gone all the way into the slot and has clicked into place. Make sure the size of the SD card you are inserting is supported by your tablet. (Check the specs in the full manual) If the SD card is larger than what is supported, it may not register with the operating system. Try formatting the SD card on a PC with a card reader and then inserting it into your tablet. (Use FAT32 format).Try another formatted SD card and see if it is recognized by the tablet.

Remove the SD card, reboot insert the card. Is your Card reader enabled in Device Manager? Have you done any updates? install the Card Reader driver. Toshiba Support : http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/home.jsp

You don't give any brand name or model number of some "microscope" Most microscopes have no SD card slot, so yours must have a camera inside it and a memory recording unit for taking shots.. Contact the maker, whoever that is, for customer support that you already paid for.
That is all that can be suggested from so few details.

it could be that your phone does not support high capacity sd cards (SDHC). Check the users manual to see what types of cards it supports and if SDHC is listed.

hey you cannot transfer contact in sd card, unlike the picture images etc. but phone contacts you cannot,

Memory card support : SD/MMC up to 2 Gigabyte and SDHC up to 8 Gigabyte

Pls. use the supported SD card.

That depends on the camera. If the camera supports Sandisk Micro, then the SD card will fit into a slot. The slot is often located near to the battery.

You will just have to push card in and camera will automatically read card.

If camera does not read the card, ensure that the camera model can support SanDisk Micro, and that it will also support card size. Older cameras do not support big memory card (eg.4Gb)

A lot of palm haldhelds only support SD cards up to 1gb. The 2gb and up ones are not supported. So check your manual and figure out waht the maximum size of sd card is in your palm, or try a smaller size SD card.
