What's the best product for this?

1. Neighbor kid does a chore for you.
2. You want to pay them in USDC. 
3. They only have an Apple Watch.

To pay your neighbor kid in USDC using their Apple Watch, I’d recommend using a platform like Zengo Wallet. It supports sending USDC directly to a wallet that can be set up on their iPhone (paired with the Apple Watch) and integrates with Apple Pay for seamless transactions. Here’s how it could work:  
They download Zengo on their iPhone and create a wallet.  

You send USDC to their wallet address (they can share it via QR code or text).  

They can store the USDC or convert it to fiat later via Zengo’s sell option.
It’s secure, user-friendly, and perfect for someone new to crypto. Have they used a crypto wallet before, or is this their first time?
