Network Tokens
Tokenized card credentials issued by Visa, Mastercard, and Amex that replace the real PAN at the merchant. They auto-update when the card is reissued, lifting authorization rates by 2-7 percentage points on subscription renewals.
Network Tokens
A network token is a card credential issued by the card network (Visa Token Service, Mastercard MDES, Amex Token Service) that stands in for the underlying primary account number (PAN). When a card is reissued — expired, lost, replaced — the network silently updates the token to point at the new PAN, so the merchant's stored credential keeps working without the customer re-entering details. The result: authorization rates on recurring charges typically rise 2-7 percentage points, and "card declined: expired" events drop sharply.
VULK relies on network tokens through Stripe, which provisions them automatically for eligible cards saved at trial signup. Combined with the PSD2 mandate captured under 3D Secure, network tokens are the second half of why VULK's subscription renewals settle reliably — the mandate makes the issuer accept the off-session charge, the network token guarantees the credential is still valid.
Adaptive Pricing
Stripe's feature that automatically presents prices in the customer's local currency at checkout, based on geo-detected location. VULK uses Adaptive Pricing on top of a EUR / USD geo-routed base price.
Riverpod (Flutter)
A reactive state-management library for Flutter — a modern replacement for Provider — built around compile-safe Providers, async value handling, and code generation. VULK's Flutter generator uses Riverpod 2 by default.
