Business cards are so 20th century. With modern smartphones and
constant data sync across virtually everything we do, there's almost no
reason for us to manually enter phone numbers anymore. You can share
your own contact info with another Android device by opening up your
contacts app, tapping on your own entry (if your phone's app doesn't use
one, create one), pressing your phone against the other and "beaming" it
While this method is hardly time-consuming, there are still occasions
where you don't want to stop someone and explain why they need to
press their phone against yours. In that case, you
pass off NFC tags pre-programmed with your
contact info and let them input it at their own
pace. On a very simple level, you can buy NFC
tags in bulk for cheap. If you want to get fancy
though, you can get business cards with NFC built
in. While this may seem redundant, it can be a
nice way to grab someone's attention, as well as
include a bit more info than you'd otherwise be able to print on
