Case study — proposal in progress
Proposal submitted — partnership decision in progress

A point of sale that speaks your customer's payment language.

Millions of travellers arrive in Canada every month without Canadian currency — and pay for it, literally, in conversion fees. I researched, designed, and pitched a point-of-sale concept that lets Canadian merchants accept the mobile, QR, and crypto payments travellers already use at home. It was proposed to Moneris, one of Canada's largest payment processors, and I'm actively looking for the right partner to bring it to market.

The problem
More than 1 million travellers arrive in Canada without Canadian currencies — most face high conversion fees and, for the large share arriving from China, language barriers at banks.

Research

I ran interviews and desk research to find out where the friction actually lived — and it wasn't just the exchange rate.

Market data: cash payment share declining, mobile payment share rising over recent years; demand for mobile and crypto payment skews toward adults 22 to 44.
User persona

Research pointed to a recurring profile — someone financially independent, mobile-first, and frustrated by exactly the kind of friction banks were creating.

User persona: Mia Nikki, 24, single, UI/UX designer in Toronto. Prefers mobile pay and crypto, is frustrated by extra money-exchange fees and payment cards not being accepted, and wants freedom to spend anywhere without going to a bank.
The gap

Banks that do offer multilingual service rarely advertise it — it's not on their websites or storefronts, so most travellers never find out it exists.

Most stores don't support the payment systems travellers already use, which pushes people back toward banks and exchanges — the exact friction they were trying to avoid.

And short-term visitors won't open a Canadian bank account just to get a better rate for a few days.

The gap: multilingual bank services are undiscoverable, most stores don't support popular payment systems, and travellers won't open a bank account for a short stay.
The solution

Enable a better money-exchange experience — at the point of sale itself.

Whether the friction is a language barrier or a payment method a store simply doesn't accept, the fix is the same: build the most popular payment system for a traveller's country of origin directly into the store's point of sale.

Two solution paths considered: (1) a real-time conversion agreement with a bank, paired with China's most popular payment provider, since most travellers arrive from China; or (2) a real-time conversion agreement with the central bank, paired with a globally popular payment provider.
Mapping the system

From task flows to information hierarchy to a full end-to-end user flow — before any pixel got designed.

Information hierarchy after card sorting: main functions, sub-functions, and individual actions mapped and prioritized by how often users needed them.

Usability testing

Two rounds of testing, validating assumptions against how people actually reacted to the interface.

"I need financial spending freedom no matter which country I visit. I don't want money exchange, banks to charge extra fees."

— Mark Solomon, usability test participant
Usability testing notes: user details, use cases, goals, highlights including 'international payment accept in store POS' and 'Alipay accept', and background on why exchange fees frustrate travellers.
Usability results: accepting mobile and international payment and inventory alerts rated as favourite features; suggestions included 24/7 support and low data usage; store owners near tourist spots reported losing customers over unsupported payment methods.
Final UI

Four core screens, shaped directly by what testing surfaced.

Product menu screen with category filters and item grid.

Product menu

Category filters up top, a scannable item grid below — built so an employee can ring something up in a couple of taps, not a search.

Checkout screen showing price, HST, tip, subtotal, and a clear step indicator from Added to Done.

Checkout & payment

A step indicator (Added → Tipped → Checkout → Done) keeps both employee and customer oriented — and this is where mobile, QR, and crypto payment options live.

Business dashboard showing transactions, top items by sales, payment type breakdown, and customer stats.

Dashboard

The owner's view — transactions, top items, payment-type breakdown, and stock alerts, so nobody runs out without warning.

Transaction history screen with refund options, transaction IDs, and timestamps.

History

Every transaction, searchable, with refunds handled right from the list — no separate tool needed.

Where this stands

Proposed. Not yet decided. Still moving.

This was proposed to Moneris as a full end-to-end concept — research, UX, UI, and a business case for implementation. That decision is still in progress. In the meantime, I'm actively looking for the right partner to help bring it to market — a payment processor, a POS company, or a merchant network that feels this friction too.
