I just located the user's manual for the ID Mate online and it states that it uses a CompactFlash card that is specifically formatted for the ID Mate, so the answer is that it uses the same kind of card (Type I CompactFlash) as the Book Port. However, you apparently can't format new cards for the ID Mate in a card reader that's attached to your computer. Most card readers attach by way of a USB cable to one of the USB ports on your computer, although there are a few somewhat more expensive versions that will actually install into the front panel of a computer just like a floppy or CD drive. ----- Original Message ----- From: "Robert Clark" <rclark0276@xxxxxxxxxxx> To: <bookport@xxxxxxxxxxxxx> Sent: Friday, March 02, 2007 12:52 PM Subject: [bookport] Re: Labeling and Storing Flash Cards for the Bookport While talking about flash cards for the BookPort, let me ask this. Currently I dont have anything that uses flash cards but am waiting for not only the BookPort but an ID Mate. Does anyone know what kind of card the ID Mate uses as well as the BookPort? I will need extra cards for both and want to be sure I order the right ones. Also, I want to install a card reader into my PC. Preferably interanl. Any recommendations? Thanks. And I bookmarked the site that was shared here, looks nice.
