ChallengeCreate four independent interfaces for patients across ages and abilities.
Core decisionPrioritize clarity, fallback paths, and continuity across touchpoints.
EvidenceA launched product, highest rating, and public comments about speed and ease of use.
Context and challenge
Grupo Sabin was creating a paperless unit without traditional queues, where technology would mediate the on-site journey. The challenge was not simply digitizing steps: patients of different ages and abilities needed to use every interface independently, often while physically and emotionally vulnerable.
As the project’s sole Product Designer, I interpreted the predefined requirements, researched references, structured the flows, and prototyped the check-in kiosk, queue display, collection-room screen, and feedback form.




Design decisions
QR scanning is the kiosk’s primary path, while manual order entry provides a fallback when the camera or code fails. Addressing patients by name confirms successful identification and makes the interaction feel less generic.
The four interfaces were designed as one connected experience. Components, language, and feedback patterns repeat across devices, while each surface responds to its context.
Outcome and retrospective
Following launch, the Digital Unit received the highest Google rating. Public reviews are qualitative signals rather than proof that design caused the outcome, but comments mentioning speed, convenience, QR Code use, and ease of service connect directly to the experience we designed.
