My suggestion is a variation of Kevin's. Adhesive strip on SD card
(exposed 1/8 th inch). This would require removing XO back to remove
strip /card.<br>
<br>
Second variation: jam lock/unlock tab. There is a slot in the card
holder metal can. Inserting a small plastic piece (tape in place) will
block the tab so SD card can not be removed..<br>

Adam, we tried silicon over the slot applied from the inside, not glue. :-) Cards fail, and removing them once the case is off, without causing damage, was also a 'use case'.

What ended up being a more reliable method to prevent theft, was not using micro-SD's in adapters, but only full size cards. Then, one educates the students that the cards have great value in the machines, and because of their size and 'formatting', virtually zero use outside of them. Manually monitoring the machines state also works when they are used mainly in classroom settings and are 'assigned' to specific students. Very few of our user base have the ability to quickly take a case apart, or know how to repartition cards that use unix file systems. Since there are also few devices in the environment which can take a native full size card, the trouble to steal them, is usually more than it's worth.
