Fatal mistake: Built a hardware solution (a consolidated payment card) at the exact moment the market was moving to mobile payments — Apple Pay launched three days after Coin's first major press coverage in November 2014, instantly making the physical card format feel dated.
Evaluating only Coin’s profile at its peak — without knowing the outcome — the model ranked Unit economics as the #1 likely cause. Documented cause: Market timing.

Documented cause
Coin launched in November 2013 with a concept that felt genuinely clever: a single credit-card-sized device with a small display and Bluetooth that could store up to eight payment cards. Users would load their cards via a smartphone app and a card reader, then use the Coin card at any magnetic stripe terminal, toggling between cards with a button press. It seemed like an elegant solution to wallet bloat.
Coin raised roughly $50 million and generated substantial media enthusiasm. But the timing was catastrophic. In November 2014, Apple announced Apple Pay — a contactless payment system using the iPhone 6 and Apple Watch that required no physical card at all. Google Wallet had existed since 2011 and was gaining momentum. The industry was moving to NFC contactless payments, making magnetic stripe hardware — the technology Coin was built on — a path toward obsolescence.
Coin 2.0 shipped in mid-2016, 18 months late, with both NFC and EMV chip features added in response to market shifts. But the product suffered reliability problems, and banks began blocking Coin-initiated transactions due to security concerns about the consolidated card model. In May 2016, Fitbit acquired Coin for an undisclosed sum — widely reported as an acqui-hire to bring Coin's payment and NFC technology into Fitbit's wearables platform. The Coin product was discontinued in early 2017. Users received no refund; existing Coin devices were allowed to continue functioning until the company sunset its servers.
Lesson
“Hardware startups must model the world their product will ship into, not the world it was designed in — platform shifts can obsolete an entire product category before a single unit ships.”

FAQ
What was Coin?
Coin was a Bluetooth-connected credit card that stored up to eight payment cards on a single device. Users loaded their cards via a smartphone app and toggled between them with a button on the card, using it at any magnetic stripe payment terminal.
Why did Apple Pay kill Coin?
Apple Pay launched in October 2014 as a contactless payment system requiring no physical card. It made the entire premise of a consolidated physical card irrelevant — the solution Coin offered (fewer cards in your wallet) became moot when your phone could replace all cards entirely.
Who acquired Coin?
Fitbit acquired Coin in May 2016 in what was widely reported as an acqui-hire — buying Coin primarily for its engineering talent and NFC payment technology to integrate into Fitbit's wearable devices. The Coin product itself was discontinued in early 2017.
Did Coin ever ship a working product?
Yes — Coin 1.0 shipped in mid-2015 and Coin 2.0 with NFC/EMV chip capability shipped in mid-2016. Both versions worked, though with reliability issues. The product was real; the market timing was not.
