I can’t claim to be hip to the latest in wedding technology, however I like the idea behind these ultra-personalized fingerprint wedding bands by Etsy seller fabuluster. Besides being a cute way to stay connected to your significant other and yada yada, they are also a great way to identify a would be romantic impostor. Just measure up their fingerprint to the record you keep on you, and you will never be fooled by an amorous doppelgänger again! Well, unless they have figured out how to clone fingerprints, but in that case we are probably doomed anyway. [Thanks Matt!]
