It is pointed out in the passage that a person carrying a mobile wallet does not need to ----.
When you walk into a store and submit your shopping
list, a map directs you to the chocolate ice cream you
crave. When you get to the front of the line, you just
bump your phone on the reader and also get a discount
via an e-coupon you have downloaded. You can scan
pictures of the spaghetti and salad you want for dinner
from the supermarket as you wait for the train and pick
up the bag on your way home. 2013 was the year the
increasing popularity of the mobile wallet – a smart
phone that also acts as a credit card, cheque book and
a useful tool that helps shoppers collect product
information – radically altered shopping habits. It has
been the biggest thing in retail since the credit card got
us talking about a cashless economy. The driving force
is communication: cash cannot communicate, but
phones can. Your alarm clock, radio, camera and even
your laptop have already been displaced by your phone.
“Everything eventually migrates to the cell phone. Since
it moves, people tend to do a lot more of it,” says Scott
Ellison, an analyst in the mobile industry. It has now
become apparent that our wallet has also moved into
the cell phone.
