Claudia - Inyo Team
Payment technology writer at Inyo Global
Claudia writes about payment technology, cross-border money movement, and fintech infrastructure for the Inyo Global team. Her work covers the full money-movement stack — from card-network mechanics like AFTs and OCTs to compliance regimes (PCI DSS 4.0, Visa AFT mandate, KYB), authorization-rate optimization, payment tokenization, and the orchestration patterns that power modern payment platforms.
Her articles are written for fintech operators, money transfer businesses, and engineering teams building payment products — people who need depth, not marketing fluff. Where claims involve specific network rules, regulatory deadlines, or industry data, she sources them from primary documentation (Visa, Mastercard, the PCI Security Standards Council, NACHA) wherever possible.
