The first modern US instant payment system, operated by The Clearing House (owned by 22 of the largest US banks). RTP launched in 2017 and supports credit transfers up to $10M (raised from $1M in February 2025, which is why network value jumped sharply that year) with immediate finality — no chargebacks or returns. It also offers Request for Payment (RfP) messaging for bill pay and invoicing. While FedNow provides Fed-backed infrastructure, RTP has a head start with broader bank connectivity and higher transaction limits, and processes the majority of US instant payment volume today.
Sweden's dominant mobile payment app used by 8M+ people (in a country of 10.5M) for P2P transfers, in-store payments, and e-commerce. Swish transactions clear through the Bankgirot Immediate Payments (BIR) real-time clearing system. Founded by six major Swedish banks, Swish has been a key driver of Sweden's shift toward a nearly cashless society. Payments are initiated via phone number and settle instantly, with merchant payments supported via QR codes and Swish for Business.
