Tech 2 32mb Card

Hi everyone. Ive got a Tech 2 scanner with software up and to 2002 on a 10mb pcmcia tech 2 card. Now i want to update the scanner and was told i need a new 32mb pcmcia card. Will any 32mb pcmcia card work or does it have to be a Tech 2 Card. Are they not all the same as long as the pins are the same number and card fits. I see some for 28 bucks and some for Tech 2 ae 500 what is the difference. If someone could expalain the difference and can i use a generic card . Thanks in advance.:)
