One of the great features of the Kindle Fire is that it's fully-integrated with Amazon.com's one-click payment system. Buying e-books, streaming movies, magazine or newspaper subscriptions, apps, or anything else on Amazon is just a convenient one-click process. That's nice, until your kids get their hands on it and goes on shopping spree in the appstore.

Here are two things I did with my Kindle Fire before handing it to my kids:

1. DELETED PAYMENT METHOD ON THE AMAZON'S WEBSITE
I deleted my payment method on the website. Don't bother looking for it in the Kindle Fire; you won't find options for it. On Amazon.com, you can turn off the one-click feature for everything except apps, which makes this whole set of options pointless because your kids can still buy apps. As of now, the only way to protect yourself from unintended purchases is to just delete your payment info on the website.

Now, if you want to buy anything with your Kindle Fire, you'll have to re-enter your payment info and re-enable one-click online. It's not ideal, but there's currently no parental controls on the device. Here's an opening for a developer to create an app for it.

2. TURN OFF WIFI WHEN IT'S NOT IN USE
The next thing I did and continue to do is turn off wifi whenever I'm not using it. Wifi emits radiation, and although the wireless carriers tell us the amount is harmless, a recent study showed that kids' brains are more affected by it. Just to be safe, I turn it off when it's not being used. This has the added benefit of saving battery too.
