I designed DineTap’s POS experience across terminals, tablets, and mobile payment devices to help hospitality staff find items, manage orders, and complete payments under pressure. The work covered restaurant workflows and a focused LITE POS experience used at the 2023 Singapore F1 Grand Prix.
Role
Product Designer (UI/UX)
Collaboration
CEO, Product Manager, and Developer.
Timeline
Three-month sprint
Platform
POS terminals, tablets, and mobile payment terminals.
The design supported the operational goals of faster service, accurate order entry, and easier staff onboarding across hospitality environments. Event deployment demonstrates usage context; it does not by itself establish measured improvements in speed or error rates.
A focused high-volume POS
The original reports deployment of the LITE interface at the 2023 Singapore F1 Grand Prix, providing a concrete operational context for the design.
Clearer order-entry interactions
Categorised menus and oversized touch targets gave staff a more structured way to find and select items.
Support for everyday restaurant complexity
Nested modifiers, visual split-bill interactions, and order-status cues addressed tasks beyond basic item selection.
A single POS ecosystem had to support different service pressures
DineTap needed to serve dine-in restaurants, quick-service environments, and high-volume event stalls. Staff had to locate items, manage custom orders, split bills, and take payments while keeping service moving. Crowded interfaces and long interaction sequences could make those tasks harder during a rush. The design challenge was to keep common actions easy to find while retaining the capabilities required for more complex restaurant work.
I analysed how staff interacted with POS interfaces on the floor. The original account identifies screen scanning, menu organisation, and readability as important contributors to service friction.
That established a direction of glanceability under pressure: structure the screen so staff can recognise the next action quickly in a busy environment.
The original describes this analysis but does not specify an observation sample, timing study, or formal usability-test method.
Organise menus around findability rather than item count
Stakeholders wanted a simple interface while also asking for all menu items to appear on one screen. I advocated for categorisation because displaying more options can increase the effort needed to locate the right item. The resulting modular grid used larger touch targets and a more structured menu presentation.
Prioritise frequently ordered items in the LITE experience
For high-volume food-stall service, I strengthened the hierarchy around fast-moving items, placing them higher in the interface and lowering the prominence of less frequent options. This tailored the design to a narrower service context. The original reports that the LITE POS was deployed at the 2023 Singapore F1 Grand Prix.
Keep modifiers and split bills manageable
I nested menu modifiers so customisation did not overcrowd the main ordering view. I also designed a visual, drag-and-drop-style split-bill interaction to make allocation more tangible. These flows addressed common restaurant exceptions while preserving a focused primary screen.
The POS design combined categorised item grids, oversized touch targets, nested modifiers, visual split-bill interactions, a consolidated payment view, and clear order-status presentation.
A focused LITE variant prioritised high-frequency items for event food stalls, while the wider ecosystem covered terminals, tablets, and mobile payment devices.
I worked with the CEO, Product Manager, and Developer during a three-month sprint. The original identifies the 2023 Singapore F1 Grand Prix as a deployment context.
The documented inputs include analysis of staff interactions and stakeholder discussions about interface density.
The original reports event deployment and improvements in checkout, training, errors, and sales. It does not provide timed task results, error counts, a training comparison, or a method for attributing sales to the interface.
The following learning statements are proposed reflections for your review.
Fewer taps are useful only when actions are easy to find
A dense interface can shorten a sequence while increasing search effort. Menu organisation and recognition need to be considered alongside tap count.
Service context should shape the information hierarchy
A food stall at a major event has different priorities from a dine-in restaurant. A focused variant can give the most relevant actions greater prominence.
Exception flows are part of everyday service
Modifiers and split bills deserve deliberate design because they occur within the same pressured environment as routine order entry.
Let's work together
Good products rarely need more complexity.
They usually need someone willing to understand the problem deeply enough to remove it.
If you’re building something ambitious and need a senior designer who can move between product thinking, interaction, craft and delivery, I’d love to talk.
