Market Context 2026 — Mobile Wallet Adoption in the U.S.
Mobile wallet payments now represent over half of in-person digital transactions in major U.S. metros.

- Tokenized transactions are the default security layer.
- Mobile wallets increasingly replace physical card usage.
What Are Apple Pay, Google Pay & Samsung Pay?

- Biometric protection built-in
- Near-instant payment experience
Cons
- Requires NFC-supported terminals
- Device battery dependency
- Some regional merchant gaps remain
