Instead of using a credit card or smartphone to pay for your goods,Amazon wants you to use your
hands.In a blog post,Dilip Kumar,vice president of Amazon Physical Retail introduced the company's
palm recognition(掌纹识别)technology,.known as Amazon One..The technology,first rolling out in
Amazon's home market of Seattle,will use people's palms to identify(them and combine that
with details of the palm,such as lines and ridges(突起),to build“"palm signature”.
In addition to the trial in the company's stores in Seattle,starting today,Kumar added that Amazon
One will come to other Amazon stores and will be used for more than just paying with your palm."We
believe Amazon One has broad applicability beyond our retail stores,so we also plan to offer the service
to third parties like retailers(),stadiums,and office buildings so that more people can benefit from
this ease and convenience in more places."Kumar added.
Though Amazon has introduced other ways to pay for goods at its physical stores,including the use
of cameras and an app linked to your Amazon account.Kumar explained palm recognition offers another
level of privacy.
"We selected palm recognition for a few important reasons."Kumar wrote,"One reason was that
palm recognition is considered more private than other biometric(生物统计的)identifiers because you
can't determine a person's identity by looking at a picture of their palm.It also requires users to make an
intentional gesture by holding their palm over the device to use.This puts customers in control of when
and where they use the service.What's more,it's contactless,which we think customers will appreciate
especially in current times."
"To use Amazon One,people don't need an Amazon account,but simply phone number and a credit
card.For those concerned about privacy,"Kumar wrote,"users can delete their biometric data if they
decide they no longer want to use it."
