What if you could hear your money? Our project, Piggy Pay, is a collaboration between Interaction Design and Advanced Product Design, inspired by the sound of coins in a piggy bank. We explored how modern digital transactions often feel intangible—just numbers on a screen
By designing a playful, tactile, and sound-enhanced experience, we aim to make saving and spending more intuitive, engaging, and fun. Piggy Pay brings money to life through sound, movement, and interaction—helping young adults develop smarter financial habits in a delightful way
