I finally was able to find a good for of those old (ancient!) SD cards I have flying around. The ministry of education in Bavaria requires that I send exam questions to them before use, by mail (the one without an e-). I can burn the questions to a CD, or put them onto a USB stick, but I presume I can also use my old SD cards. Yay for reuse!
