The Point of Sale system is the device used by station attendants to issue new PRESTO cards, load money onto a customer’s PRESTO card, query PRESTO cards, refund cards, card configurations and more. The project is to work on the next generation of the PRESTO POS system as it is due for an upgrade in both hardware and software. The goal is to allow an improved customer experience and extending the capabilities that are currently available.

User Research

We conducted user interviews to determine their motivation and pain points. Taking the information we gathered, we were able to put together personas that best represent real users. Creating user journeys and scenarios allowed us to empathize with the real users to determine what makes an improved product.

Presto Persona

User research allowed us to discovery useful information that helped determine the design of the product:

  • Majority of users interact with SPOS system using the touchscreen
  • 70 - 80 % of transactions are on Presto Cards
  • Most used payment methods are credit + debit
  • The most common transactions are loading money, single ride tickets, and underpayment management
  • Search results/suggestions for stations are not clear, due to the abbreviations system used
  • Attendants currently use a different computer for other feature

Presto User Scenario

Design Sprints

Our goal was to solve for user-focused challenges and identify opportunities for improvement. We did this by running a series of design sprints, which helped us to reach clearly defined goals and deliverables and gain key learnings, quickly.

The design sprints generally involved 3 out of a 5-day cycle. Each week were came up with designs for a specific set of features and we presented back wireframes and a quick prototype (built in Axure) to the stakeholders and end-users for feedback. Often times, it’s hard to get the budget and availability for frequent testing but we did manage to include testing sessions every two weeks which worked out quite well.

Visual Design

The PRESTO rollout is at full speed on the TTC with their recent rebranding. We needed to make sure the visual design of the POS system is consistent with the new brand image. Not only we were tasked with designing the UI for the POS system but to create the standards for all future digital products.
