Castles Technology Brand Guidelines: A 1993 Taiwan Terminal Maker That Bought Spire Payments

Terminals, cash registers and leasing.

Castles Technology — in Chinese, 虹堡科技 — was incorporated in Taiwan on 20 April 1993, according to the company’s financial statements as quoted by the Taiwanese market site nStock in 2026. Those statements describe its business as financial products for consumers, electronic payment terminals, electronic cash registers and peripherals, sold and leased. The company dates itself to 1993 as well, in its exhibitor profile for Nikkei’s RetailTech Japan show, and in its listing in Visa’s partner directory.

The company is based in Xindian, a district of New Taipei City that lies just south of Taipei, according to its investor pages; the market data site Stock Analysis also gives New Taipei City. The Visa directory text describes its headquarters simply as Taipei.

Castles came to the stock market in two steps. Its shares were approved for trading on the emerging-stock board of the Taipei Exchange on 14 November 2011, and in October 2016 it passed the listing review of the Taiwan Stock Exchange, with its shares listed there in December 2016, according to the same financial-statement note. It trades under stock code 5258, as Stock Analysis also records.

The company’s website names Kevin Hsin as chairman. It describes Castles as a top-four terminal maker worldwide, says it has sold more than 4.2 million units and serves more than 150 countries, and lists 718 employees; the Visa directory text calls it one of the top five. Those are the company’s own figures and rankings. The same Visa text lists the sectors Castles sells into as vending, finance, retail, hospitality and transport.

Android terminals, vending and Spire Payments.

Castles’ website groups its payment devices as countertop machines, portable handhelds, mini POS units, multilane PIN pads for supermarket checkouts, unattended readers and integrated POS. Many current models run Android, with a smaller group of Linux terminals such as the V1C countertop machine.

The Android range carries short codes. The S1F4 series covers handheld terminals, including the S1F4 PRO and the S1F4 MAX; the S1MINI2 sits in the mini POS group; the S2T is a tablet POS that the company pitches at boutiques and fine-dining restaurants; and the S1U2 family covers readers built into vending machines, parking and ticketing. In a 2025 exhibitor note for London’s Retail Technology Show, Castles said it was showing Android 13 terminals including the S1Mini2, the S1F4 PRO and an S1U2 model for vending and electric-vehicle charging.

Software sits alongside the hardware. The company’s cloud platform, CasHUB, manages terminal fleets, and Castles also offers SoftPOS, which lets a phone or tablet accept cards. In its RetailTech Japan profile the company describes a shift from hardware maker to what it calls “Terminal as a Service,” combining devices, software and cloud services, and says it has regional offices in Europe, the Middle East and Africa, North America, Latin America and the Asia-Pacific region.

Japan is one of its markets. The same profile says Castles has a high share among Japanese department stores, retailers and restaurant chains, working with local payment networks; that is the company’s description. At RetailTech Japan, its profile says, it was introducing the S1E4 PRO, a lightweight Android terminal for food service, retail and department stores.

Payment terminals are made to be handled, and their makers tend to show them in use: a countertop unit beside a till, a PIN pad turned towards the shopper, a portable terminal carried to a restaurant table, an unattended reader fitted to a vending machine or a fuel pump. Product pictures move between that wider scene and the close-up — a card or a phone held over the contactless symbol, a receipt coming out of the printer, a total on the screen. Some pages open a device up into an exploded diagram of casing, screen, keypad and board.

Much of what these companies sell cannot be photographed at all. Their websites set hardware beside software, device management and payment services. Ingenico’s current site groups its devices by use — portable, countertop, PIN pad, mobile, self-service — before it names a range, and Verifone’s places its Victa devices alongside software, payment processing and controllers for fuel stations.

The trade meets at fairs, and launches are timed to them. Verifone presented its new identity in November 2014 in the same week as Money20/20 in Las Vegas and the CARTES show in Paris, according to the consultancy that designed it, and Ingenico showed new terminals at EuroCIS, the retail-technology fair in Düsseldorf, in February 2025, the German trade title IT Finanzmagazin reported.

Ingenico and Verifone have each changed owners more than once and kept their names. This guide sets out what can be checked about each maker — who founded it, who owns it, which ranges it sells and how its identity has changed — and keeps the companies’ own claims apart from what independent sources report.

A Taiwanese owner for a British terminal name.

The largest step into Europe came in 2020. On 2 October 2020 Payments Industry Intelligence reported that Castles had completed the acquisition of the business and assets of Spire Payments, a European card-terminal company based in the United Kingdom. Jean-Philippe Niedergang, then Castles’ group chief commercial officer, said the deal gave Castles “a major platform” to expand its reach in Europe, the Middle East and Africa, and the company said it would keep investing in Spire’s products and keep its local customer relationships.

The deal put a British terminal name alongside the Castles range. Spire Payments’ own history is the subject of a separate guide.

The company also sets out environmental aims. Its sustainability page, introduced by Kevin Hsin, says that in 2024 Castles gained EcoVadis recognition, completed a carbon inventory verified to ISO 14064, and cut plastic in the packaging of selected products by 99 per cent; it also names a net-zero goal for 2050, and says its approach follows frameworks including the UN Global Compact, the GRI Standards and the Responsible Business Alliance code of conduct. Those are the company’s statements, set out in its own ESG reports.

The name needs care. Castles Technology, with an s, is the Taiwanese terminal maker; Castle Technology, a British computer company named after Framlingham Castle, is unrelated. Its model names, like the S1F4 or the V1C, are short codes rather than words.

Where the terminals are made is not set out in the sources used here.

For a design guide, Castles shows how a terminal maker from Taiwan built a wide device range under short codes and then added a European name by acquisition. Compare Spire Payments, the British terminal business it bought, and PAX Technology, a terminal maker from Shenzhen. For this guide we use a harbour navy, a sea teal and stone with a sans, an unofficial interpretation; no product or logo is reproduced.
