Gating entrances with Stripe and NFC passes

Joshua Nussbaum's recent article introduces a modern approach to access control by integrating Stripe payments with NFC-enabled digital passes. Instead of traditional physical keys or cards, users receive digital passes compatible with Apple Wallet and Google Wallet, allowing seamless entry through NFC readers.

The system comprises two main components: a public-facing website for Stripe Checkout and pass issuance, and a private access control system running on a Raspberry Pi. This setup verifies membership status via the Stripe Subscription API and unlocks doors accordingly. Hardware requirements include a Raspberry Pi Zero 2W, VTAP100 NFC reader, an electronic door strike, and a 3.3V relay.

For developers, the article provides a comprehensive guide, including a wiring diagram and step-by-step instructions, to implement this solution effectively. By leveraging existing digital wallets and NFC technology, this approach offers a streamlined, contactless access experience.
