Overview
K PLUS is Thailand's #1 mobile banking platform, operated by Kasikornbank (KBank) [1, 2, th-cro]. 2025 forecast: 23.9 million users + 30% Thai market share — up from 16M baseline reported in 2018 Asian Banker coverage.
Distinctive K PLUS dominance: more than 1 in 3 online transactions in Thailand take place on K PLUS [3]. 2025 international expansion: bank seeks expansion in China + Vietnam + Indonesia; K+ Go Inter feature enables scan-and-pay across 47 countries — Thai-tourists-abroad gateway.
