SnowShoe

SnowShoe designs and builds small 3D-printed plastic stamps with unique patterns imprinted on them for interaction with touch sensors on smartphones and tablets. The patterns mimic human fingertip contacts in a specific configuration and can trigger specific interactions within apps when placed on a device screen, functioning as physical-digital bridge tokens for IoT applications. The company's technology operates as RFID-like tags that use capacitive touch screen sensing rather than radio frequency, enabling secure authentication, loyalty program integration, gaming interactions, and payment verification through simple physical-to-digital touch interactions. SnowShoe's stamps provide a tangible interface layer for mobile applications, enabling brands to create physical touchpoints that seamlessly connect to digital experiences. Founded in 2010 and headquartered in San Francisco, the company has raised approximately $7.7M in seed funding. SnowShoe differentiates itself through its zero-electronics, zero-battery approach to digital authentication, using precisely manufactured physical patterns that interact with existing capacitive touch screens to create verifiable digital-to-physical connections for IoT infrastructure applications.
