Folks, this is one of the coolest things I’ve ever seen. I highly recommend “The MicroNickel,” a hollow US Nickel from Dereu & Sons Mfg. Co. at spy-coins.com.
There are other coins too, but I like the feel of the nickel and it is only $30. For an additional $5 to $10 more you can get a 2GB micro SD card to fit inside the nickel. If you need more space, there are also 32GB cards (same physical size) for about $50 at the time I’m writing this. By the time some of you read this, there may be much larger micro SD card capacities. I wouldn’t mind a 32 TB micro SD card. That would be super cool. But even 2 GB is a lot. (2GB holds about 360 songs @ 192kbps, or about 560 songs @ 128kbps. )
I also recommend using TrueCrypt to encrypt whatever you store if you want to keep it private. Encryption is good for storing your taxes, legal documents and medical records in your nickel vault. Then put your secret nickel in a big jar with hundreds of ordinary nickels. When it is time, use the weight difference or some other trick to find your hidden data.
I’ve added a new “Recommended Products” category on the top left menu tonight with a permanent link to spy-coins.com. Buy a few for friends, and tell them Xeno sent you!
