Castles Technology

What it does

Castles Technology earns from selling hardware rather than from payment volume. Its 2024 Annual Report, the statutory annual report filed on Taiwan's Market Observation Post System, says the company independently designs and develops the electronic fund transaction terminal (POS) as its major product, and the business ratio table in that report puts electronic fund transaction terminals at NTD 6,299,113 thousand, or 80.49 percent, of NTD 7,825,651 thousand of 2024 revenue, with electronic cash registers and peripherals, personal financial application products and a residual others line making up the remainder. The paying customers are mostly not merchants: the report describes downstream customers as primarily regional system integrators or distributors, which then connect the products for financial institutions, end merchants and retailers, alongside the company's own overseas subsidiaries. A second and much smaller stream is software, since the same report says that on top of remote software update and maintenance services Castles offers a software subscription service on its Castles Terminal Management System so that banks can build their own terminal app ecosystem.
