Losing your wallet can be devastating, because it doesn't just mean lost money, but rather several cards that will take many hours to replace. Plus, if it results in identity theft you could be paying for that one little error for several years. According to personal finance magazine SmartMoney, you can improve your chances of getting your lost wallet returned by simply including a photo:
According to a 2009 study by psychologists in Edinburgh, Scotland, a lost wallet is far more likely to be returned if it has a picture or two inside. The return rates were highest (88 percent) for wallets that included a baby photo. (Just about one in two wallets with a pic of a puppy were returned.) Those without kids, though, need not worry. Says Richard Wiseman, the author of the Edinburgh study: Get a photo of the "cutest baby you can find" and make sure it's prominently displayed.
So if you want to improve your chances of getting your wallet back and you don't have kids or a puppy, now's a good time to do a quick google image search and hook up your printer.
