Do you trust Amazon with your palm print?  Amazon rolled out its new palm scanning technology to several cities all over the country this year. It is now possible to pay for products in a store by simply passing your hand over a scanner. Is this an exciting innovation bringing unprecedented convenience or a potential security risk that could result in a loss of privacy?                                                                                                                                                                                                                                                                                                                                                                                                 Amazon One payment technology was recently rolled out at Whole Foods stores - in the southern California region, including LA, Malibu, Santa Monica, Irvine, Playa Vista, Sherman Oaks and more. Northern California has also seen Amazon Go stores already have a presence in the Bay Area, with four locations in San Francisco. The East Coast has seen one of the biggest rollouts of Amazon's contactless payment at ten Amazon Go locations, two of which also offer Starbucks pickup.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   All in all, Amazon's palm scanner is currently available at 156 business locations accross the U.S.. They describe this new system as a "fast, convenient, contactless identity service that uses your palm. The new palm scanner has been dubbed "Amazon One" by the retailing giant and is primarily branded around the selling point of convenience. Amazon's hardware captures the features of your palm, including your unique 'subcutaneous vein pattern and surface lines'. The result is your one-of-a-kind palm signature.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       Palm scanning technology is based on the fact that everyone has a completely unique palmprint. Security experts consider palm scanning to be one of the most secure forms of biometric authentification because, unlike your face, your handprint is not easily photographicable by criminals, making it more difficult to steal. The system requires you to place your trust in Amazon's Cloud Security. You cannot change your palmprint-once stolen, it is stolen for good.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           At the end of the day, Amazon's palm-scanning payment system may be a great new convenience, but users must carefully consider whether or not they trust Amazon with their private information.  As cybersecurity threats demonstrate ever-increasing abilities to hack the latest technology, it seems only a matter of time before our scanned palm prints end up in the hands of criminals. Until consumers are ready to place their faith and trust in Amazon's security, our guess is that payment cards won't be going away anytime soon.
