The Challenge
Alcatel Global needed to decide whether it was worthwhile to invest in developing a mobile payment solution (Alcatel Pay) to compete with Apple Pay, Samsung Pay, and Android Pay in the mid-range smartphone segment.
Key issues:
Is there real demand in the Brazilian market?
What are the main barriers to adoption?
How to balance convenience and security?
What would differentiate Alcatel Pay from its premium competitors?
What is the technical and commercial feasibility?
Time to complete the design: 2 months
Business Context
Scenario 2017:
80% of card payment terminals in Brazil are already equipped with NFC (Caixa Econômica).
Apple Pay and Samsung Pay dominated the premium segment (R$ 3,000+).
No mobile payment solution available for mid-range smartphones (R$ 800-1,500).
Alcatel underwent a rebranding in 2016 focusing on Millennials.
A 12-18 month window of opportunity before Chinese competitors.
Opportunity:
60% of smartphone sales in Brazil were mid-range.
Millennials open to fintech (Nubank's growth as evidence)
Infrastructure is in place, but solutions are inaccessible to most.
Potential for significant competitive differentiation.
Why hire local R&D:
Expertise in the Brazilian local market
Risk reduction before multi-million dollar global investment.
Agility and cost-effectiveness vs. mobilizing a global team.
Validation with real users before development.
Project Objective
To map the complete mobile payments ecosystem in Brazil and validate the Alcatel Pay concept through:
Researching technologies: NFC, tokenization, security, APIs
Market analysis: Flags, banks, infrastructure, competitors
Brazilian context: Behavior, payment culture, barriers
Concept validation: Prototypes and testing with real users.
Business Goal
For Alcatel Global:
Cost reduction in R&D using the Informatics Law in the Manaus Free Trade Zone
Risk reduction of failure
Clear prioritization of critical features versus nice-to-have features
Framework applicable to other emerging markets
For the local R&D institute:
Demonstrate expertise in mapping complex ecosystems.
Proven ROI
Positioning ourselves as a strategic partner for innovation.
Becoming a preferred supplier for future projects.

CSD Matrix
Organizing knowledge into three categories:
Certainties:
Card registration, tokenization, payment authorization.
Assumptions:
Need for internet access, biometrics, transaction history.
Doubts:
Which cards are accepted, security measures, maximum value.
Hypotheses about Users
Target audience: Upper-middle and upper-middle classes (25-40 years old) who are frequent credit/debit card users.
Classes C/D with low affinity for cutting-edge technology.
App trust is a key factor (product generates anxiety)
Hypotheses about Barriers to Adoption
Cashier training: "I need to teach the employee, it takes time and irritates the queue"
Fear of embarrassment: "What if it doesn't work? I'll be embarrassed."
Battery: "What if my cell phone dies?"
Businesses: Not all accept NFC.
Backup needed: I still need to carry physical cards.
Research
We needed to understand more about PIX and users' needs regarding strong authentication for signatures. To do this, we defined some research methods:
Semi-structured interviews
Audience: Samsung Pay users
Format: Semi-structured interviews of 20 minutes.
Outline: 13 questions about setup, use, experiences, and needs.
Interview script
General Information
TARGET AUDIENCE
Users of smartphone-based card payment systems (primarily Samsung Pay).
OBJECTIVE/METHOD
Understanding what motivated the person to use Samsung Pay, how the setup process went (expectations and frustrations, areas for improvement), and how the payment was made. The collected data will be noted and, if possible, recorded in audio.
INITIAL CONTEXT/APPROACH
Opening script:
"Hi [Name], how are you? My name is [Name], I work at the R&D Institute in Manaus, and we are conducting research on new forms of payment using smartphones. We would like to understand what people's experiences have been like."
We will collect the data solely for research purposes, and no information will be disclosed to the public in any way, including your personal information.
It should take a maximum of 20 minutes, depending on the chat.
Any questions? Can we begin?

Signature with PIX, with the security of the Central Bank.

The Interface
Our main challenge was creating a reliable signature flow: during testing, some users found it strange to receive a document to sign and then make a PIX payment.
Furthermore, we needed to present information in a simple and concise way, since usability tests showed that most people didn't read lengthy texts. Even so, it was crucial to clearly state the essential points for authentication to function correctly.
Usability Testing
To assess the risk of acceptance and usability, we built prototypes for testing. We conducted 21 tests with people from within the company and some clients. After each test, we conducted interviews. This research was carried out by me and the Content Designer.
In this stage of the project, I developed the research plan. With the help of the Product Manager, we recruited users and ran the tests, which I moderated while the Content Designer took notes.
Challenges
Several interviews were conducted with people from other areas of the company who were not involved in product development; however, we would have liked to have tested with more users and non-users of the system.
We needed to simulate a scenario as close to reality as possible, as we needed to assess acceptance and understanding.
The Pix payment step required two people to simulate sending the Pix key in real time during the test.
We couldn't mislead users with too much context.
Analysis
We created a spreadsheet with each screen the user would go through, and noted positive and negative points, observations about their interaction, and tried to identify their emotions during the journey.

Lessons learned from the research
We believe that with the resources we had, we were able to achieve a fluid and simple experience for a first version.
During the testing period, we modified the prototype several times to evaluate what worked best in the interface, maintaining a cycle of evaluation and adjustments. We stopped iterating when the results started to repeat themselves.
Verbal explanations should be sufficient for quick understanding, but care must be taken not to generate further questions or display lengthy texts, as this could reduce the reading rate.
The completion of the process became faster and easier for users to understand with each iteration.
The mobile version should prioritize the use of Pix copy and paste, while the desktop version should prioritize QR Code usage.
It was essential to provide the user with context about why a payment via Pix would be requested.
We would need to generate documentation to inform the sender of the document of the importance of notifying the recipient in advance that a symbolic payment would be requested for signature.
Understanding the payment process during the process could generate doubts and insecurity, even if the transaction itself were easy to complete.

Lessons learned by the team
We achieved the company's goal of gaining visibility in the national media and consolidating the brand as innovative, but we believe we did not meet all user objectives. After further evaluation, we understood that customers needed stronger authentication for certain operations, but PIX was not legally accepted, making a Digital Certificate signature the necessary option, which we were not addressing at that time.
Usability testing was essential to ensure a high success rate in the process.
We learned to test quickly, evaluate the results, make adjustments, and test again.
Design was a powerful tool for the successful use of the solution.
Content design was fundamental in providing greater user security.
We would need to offer alternatives if the user did not want to or could not use Pix.
We would need to improve the sender's experience with the document to prevent risks associated with the use of PIX authentication.
