You can now pay anyone using Square Cash right from your Apple Watch
Context & Ripple Effects
In 2015, Square put person-to-person payments on the wrist: Square Cash now runs natively on the Apple Watch, letting users pay anyone without pulling out their phone. It's an early move in what became a decade-long Square-on-Apple pattern — Jack Dorsey later brought Square's virtual cards into Apple Pay, and by 2022 Square had adopted Apple's Tap to Pay on iPhone for sellers.
First-order effects
- Cash app users with an Apple Watch can now send payments at a glance, removing the phone from the transaction entirely.
- Square gains distribution on Apple's fastest-growing wearable surface before rivals like PayPal and Venmo — whose competition drove the earlier Cash Drawer balance feature — establish themselves there.
Second-order effects
- The watch integration pulls Square deeper into Apple's payments orbit, paving the way for the Apple Pay compatibility Dorsey announced the following year.
- Peer-to-peer rivalry shifts from feature checklists to device surfaces, forcing Venmo and PayPal to chase the same wrist real estate or cede the quick-pay moment.
Third-order effects
- If the pattern holds, payment apps stop being single-app products and become services that follow every screen a user owns — the same logic that later carried Square to Terminal hardware and seller-side Tap to Pay.
- Platform owners like Apple gain leverage over which wallets reach their devices, making hardware access a competitive gate for consumer fintech.
The trend: Consumer payments are spreading across every device surface a user carries or wears, with Square repeatedly meeting Apple's new hardware wherever it appears.
