This looks somewhat heavier/bulkier than mine and I designed a latch/lever to grab and securely hold the card using the notch that is provided on one side. I'm pretty sure this is the intended purpose of the notch.
I'm also pretty sure that most ordinary microSD cards are reasonably waterproof. On the outside, they're solid molded plastic with contacts exposed. I've used different brands in the shower over long periods of time and gone swimming with them without any problem. I just wouldn't recommend powering them up wet --- might short the contacts.
