1. Payfone
mobile payment solutions

2. Why this service was developed
Given today's security concerns and the ever
increasing popularity of credit cards, a rift
was forming: how could one safely make
payments that required reading credit card
numbers over the phone?

3. Businesses perfect for Payfone
● Restaurants with takeout/delivery services
○ Pizzerias
○ Chinese Food
○ Etc.
●
●
●
●
Television shopping networks
Magazine/newspaper listings
Other small/family businesses
Virtually any business which accepts credit
card payments over the phone

4. Security issues
When reading digits over the phone, especially
to pizzerias or Chinese food restaurants
without Point Of Sales systems, a human has
to:
● write the numbers down on the ticket
● enter the numbers into the credit card
terminal
● hand the ticket to the chef
● hand the ticket to the delivery driver

5. This leads to many obvious security
flaws
Thus, the Payfone app offers the following service:

15. Profitability
The Payfone app can be monetized in many
different manners:
● A flat merchant fee upon signing up if a
user wants to accept payments or become
listed in the search
● A per-purchase convenience charge of less
than 3% (acting as Merchant Services)
● Using a user's purchase history for targeted
advertisements

16. Google Wallet
This service can be easily integrated into
Google Wallet, as the card information already
exists and is encrypted. With this service,
Google Wallet will become more viable for
smaller businesses and businesses where
transactions cannot be made in person.
