Problem
The original NFC keychain unlocked music but gave fans little reason to collect it or artists a distinctive release format.
Approach
I originated the Artist Key and signed-card mechanic, connecting collectible identity to NFC activation, artist worlds, and creator commerce.
Outcome & caveat
Built the cards, activation flow, commerce platform, packaging, and campaign. Funding ended before validation at scale; the market outcome remains unresolved.

Explorations
Give fans something worth collecting
Early NFC chains and access tags worked, but felt like hardware. Signed Artist Keys made the artist, edition, and access clear before the first tap.
Decision 01
From keychain to Artist Key
I chose a familiar collectible format. Artist imagery, signatures, numbered editions, and color series made each Key recognizable and personal.
Decision 02
One tap to claim ownership
I designed activation to recognize the Key, reveal the artist, and confirm ownership in the fan’s vault. One gesture connected the physical card to its digital collection.
Decision 03
A card that opens an artist’s world
Fans could access releases, exclusive media, and future drops. I connected that access to creator storefronts and purchase-to-unlock commerce.
Product system
Own. Tap. Explore. Return.
01
Own
A signed, numbered Artist Key communicates identity before the phone enters the story.
02
Activate
An NFC tap identifies the object and brings the artist relationship into the app.
03
Access
The fan enters an artist world with releases, media, drops, and owned collectibles.
04
Participate
Storefronts and purchase-to-unlock mechanics extend ownership into creator commerce.

Activation, collections, discovery, and commerce in one product.
Outcome
Built for testing. Unproven at scale.
The company ran out of runway before market validation. The work reached physical prototypes, working activation logic, complete product flows, and launch assets.
- 01Produced physical card prototypes and tested NFC tap zones, material, scale, and editioning.
- 02Designed the activation, onboarding, vault, artist profile, release, and discovery flows.
- 03Defined creator storefronts and purchase-to-unlock mechanics around the Artist Key.
- 04Carried the product thesis into the web platform, brand system, and launch campaign.
