Why is my SD card not working with my TSC TTP-346M Barcode Reader?

If your TSC Barcode Reader indicates that the SD card is unable to use, it could be due to a damaged SD card. Try using a supported capacity SD card. Also, make sure the SD card is inserted correctly by reinserting it. The supported SD card specifications are 128MB, 256MB, 512MB, 1GB, and 4GB SDHC CLASS 6.
