PagSeguro NFC
Brazil's first peer-to-peer mobile payment solution, using NFC technology (near-field radio communication, where connection occurs only in short range such as on device's touch, tap, or extreme approximation).
Client:
Nokia do Brasil & UOL
Concept:
Mauricio Sá Ribeiro & Milton Onodera
UX Design & Information Architecture:
Mauricio Sá Ribeiro
Visual & Motion Design:
Milton Onodera
Development & Testing:
Nokia Institute of Technology (Manaus, AM / Recife, PE)
Platforms:
MeeGo & Symbian
In 2011, Nokia needed to establish their position as technological reference in NFC, present in most of their mid- to top-end devices, and started a program in partnership with its R&D institute in Brazil (Nokia Institute of Technology - INDT) to develop NFC solutions.
After the concept phase, focus was driven into an NFC payment solution in cooperation with local partners. Since there was no secure NFC element in the current devices, working with UOL's PagSeguro (a Brazilian PayPal alternative) was important as a technically viable alternative.
Value Proposal:
Develop a solution that allows mobile payment in a quick and simple fashion, following the premises: "easy, safe, and trustworthy".
Use Case:
Make payments in public places using only the cell phone, with a single tap (for cross-device NFC communication).

Client application
Ready to pay, an animation explains the main interaction for payment

Point of sale
The application for businesses is ready for price input, followed by an animation to explain how to proceed

Concept Selection
Having done research on the technology and usage, coupled with benchmarking, it was understood that mobile payment is desired. However, there is a common worry about its safety.

Concept Definition
During the conceptual phase, it is essential to have constant awareness of the technical feasibility, communicating with developers and aligning with business rules.
This phase consisted of the definition of scenarios, the main use case and alternative use cases, as well as feature maps, workflows and connection behavior diagrams.



Screenflow
Information architecture and complete user experience details for each application: Client and POS (point of sale)




Challenges ameliorated by usability tests and project iterations
Understanding the tap behavior, NFC feedback, the use of 2 platforms (MeeGo and Symbian), error handling and synchronization.
"Guerrilla" usability tests were done to validate and improve interface components.

Results
Very positive media feedback:
Globo News, Gizmodo, Nokia Conversations, ...
Great user response:
"Worked flawlessly"
"Quicker than all available payment methods"
"It felt like being part of the future"
The objectives were reached, and the ROI exceeded.
By November `12, it was present in 17 restaurants in São Paulo, Brazil (Spoleto, Fran's Cafe, Yoi, ...).
The program was delivered prior to expectations, with the client's maximum satisfaction score:
"[PagSeguro NFC] is probably the highest quality project I've seen at the Institute."
