Millions of people around the world use PayPal
for one simple reason: it’s simple.

$485,000
Payments processed by PayPal each minute.

Accept payments faster with integrations in
as little as 12 lines of code
By vaulting credit cards you allow users
to transact securely and easily
Through the v.zero SDK companies such as Uber, airbnb and Github are able
to accept PayPal and Credit Card seamlessly

V.Zero Ruby demo using Sinatra
This is a really basic example of the Braintree Dropin
JS Client Library in Sinatra to make a CreditCard or
PayPal payment

1969 ARPANET
A revolution begins
"We set up a telephone connection between us and
the guys at SRI ...", Leonard Kleinrock said in an
interview: "We typed the L and we asked on the
phone, "Do you see the L?" "Yes, we see the L," came
the response. We typed the O, and we asked, "Do you
see the O." "Yes, we see the O."Then we typed theG,
and the system crashed ...Yet a revolution had begun"

Mobile makes the internet portable
Augmented reality gives us a world we can see but cant touch

Virtual Reality makes the internet immersive
Fooling the brain is one thing but the body knows better

“Apps like Uber change the whole workflow
and it changes the way we think about these
things. You empower workers, and they can
have more flexibility.”
- Tim O’Reilly

IoT Apps
More Opportunities
Uber isn’t what most people would think of as an IoT
company — and that is the problem.
The alternative cab company represents the kind of
systematic change that interests him, a change that
doesn’t just focus on sticking a sensor in a gadget.

Candy Dispenser
Alberto Lopez (@AlbertusLM)
IoT project, using a common Candy dispenser
machine, a Spark core (www.spark.io) and Braintree
v.zero SDK
Github.com/albertuslm/CandyMachine

Brasilino
Jeff Prestes (@jeffprestes)
Using a Raspberry Pi the project uses a Java client to
receive commands via Socket from Mobile Remote
control andAndroid controller that will commands the
car and receive streaming from Car's camera.
The name means a mix between Brasilia (very popular
old brazilian car) andArduino.

IoT Receipt Printer
Steven Cooper (@developersteve)
Using an ArduinoYun to power a thermal receipt
printer that retrieves new orders from the Braintree
BraintreeTransaction SDK call, orders are stored in
the custom order variable which needs to be setup via
the sandbox and can be populated with JSON order
data at time of order.
Github.com/developersteve/IoTCart

IoT Receipt Printer
Enables merchants to automatically print when a new order is received on a website

The Website
• PHP Cron
• C++ Sketch
• Braintree Transaction Search
Project Overview
Receipt Printer
The Hardware
• HTML/JS
• Ruby / PHP
• Braintree Client Token
• Braintree Transaction

Step 1 -TheV.Zero
Powered by Ruby using Sinatra
31
Generate a token for the dropin UI
Add the token to the Javascript

Step 2 -TheTransaction
32
Ajax Submit the Payment_Method_Nonce
Transacting the Payment Method_Nonce

Custom Fields
33
Braintree Sandbox -> Settings -> Processing
Transaction stores the custom field if populated

Step 3 - Profit

LINUX SQLITE BRIDGE ARDUINO
Code on the Yun
• A PHP Cron checks
Braintree for new
transactions not already
listed in the bridge
referenced by the
transaction id, stores
transaction json in a file
using the transaction id as
the filename
• Stores transactions with
transaction id as the
primary key and a printed
indicator
• Checks the SQLITE
bridge to see if theres any
new transactions, if found
opens a matching
transaction id file prints
and marks as done
