Overview

Interpay Nederland B.V. was a Dutch payment processor and payment-services organization that played a central role in the country's retail and banking payment infrastructure during the 1990s and early 2000s. It was created in 1994 through the combination of BeaNet, the Bankgirocentrale and Eurocard Nederland, bringing several previously separate payment activities under a single bank-owned organization. The company was owned by a consortium of Dutch banks, with ING Group reported as its largest shareholder at approximately 30 percent. The organization operated and supported several payment systems used widely in the Netherlands. These included PIN, the country's debit-card payment network; Chipknip, an electronic-purse product; Acceptgiro, a giro-based payment method used for invoices and bills; and Incasso, a direct-debit service. Interpay therefore served both consumers and businesses, with activities spanning transaction processing, payment acceptance, card infrastructure and related administrative services. Its subsidiaries included Paysquare, which facilitated credit-card acceptance, and InterEGI, which distributed prepaid Chipknip products. Interpay was also involved in the modernization of Dutch payments. In 1995 it began a pilot of Chipknip, reflecting the period's interest in replacing cash for small-value transactions with stored-value technology. The company was regarded as an important participant in the transition to the euro, with contemporary commentary identifying its systems and operational readiness as significant to a smooth changeover. In 2003, Interpay joined Banksys and SSB in establishing Sinsys, a credit-card processing venture intended to reduce costs through cooperation among payment organizations. The company faced regulatory and commercial pressure over its pricing. In 2004, the Netherlands Competition Authority fined Interpay €30 million after finding that tariffs charged to the hospitality sector were excessive, reportedly five to seven times higher than comparable levels. Interpay was also required to reduce those tariffs. The same year, it sold its Document Services division to Unisys, indicating a move away from some non-core document-processing activities and toward payment infrastructure. Interpay reported processing 3.3 billion financial transactions in 2005, illustrating the scale of its role in the Dutch payments ecosystem. In that year it also spun off Currence, an organization associated with managing Dutch payment products and schemes. Interpay's international integration culminated in September 2006, when it merged with Germany's Transaktionsinstitut für Zahlungsverkehrsdienstleistungen AG. The combined organization became Equens, a cross-border European payment processor. Interpay therefore no longer exists as an independent operating brand, but its former systems and organizational capabilities contributed to the development of the later European payments-processing group.

History

Interpay Nederland B.V. emerged in 1994 from the merger of BeaNet, the Bankgirocentrale and Eurocard Nederland. The combination consolidated important Dutch payment activities within a single organization owned by a consortium of domestic banks. ING Group was the largest shareholder, with an approximately 30 percent interest. This ownership structure reflected the strategic importance of payment infrastructure to the Dutch banking sector rather than a conventional consumer-brand model. The organization operated several of the Netherlands' principal payment systems. PIN supported debit-card payments, while Acceptgiro and Incasso handled invoice-based and direct-debit transactions. Chipknip represented an electronic-purse approach to low-value payments and was piloted by Interpay in 1995. Interpay's role extended beyond operating schemes: it also processed transactions, supported merchant acceptance and distributed payment products through subsidiaries. Paysquare handled credit-card acceptance, and InterEGI distributed prepaid Chipknip products. Interpay became an important operational actor during the Netherlands' transition to the euro. Contemporary reporting treated the reliability of the country's payment systems as one of the conditions for a smooth currency changeover. The company also pursued cooperation beyond the Netherlands. In September 2003, it created Sinsys with Banksys and SSB to provide credit-card services and seek economies in processing. Annemarie Jorritsma became an Interpay commissioner in 2003. The company encountered significant criticism over pricing in the hospitality sector. In 2004, the Netherlands Competition Authority imposed a €30 million fine after concluding that Interpay's tariffs were excessive, reportedly five to seven times higher than appropriate comparable charges. Interpay was required to reduce the tariffs. That year it also sold its Document Services division to Unisys, separating a document-oriented activity from its principal payment businesses. Interpay continued to operate at substantial scale. It processed 3.3 billion financial transactions in 2005 and spun off Currence, which was associated with Dutch payment products and schemes. Management also changed during the final phase of the company's history: director Willem Stolwijk left in 2006 and was replaced by Ben Haasdijk. The final structural change came in September 2006, when Interpay merged with the German Transaktionsinstitut für Zahlungsverkehrsdienstleistungen AG. The resulting company was named Equens. This merger converted Interpay's primarily Dutch institutional base into part of a broader European payment-processing organization. Interpay consequently became a defunct brand, while its payment systems, processing expertise and organizational assets fed into the development of Equens and the wider European payments market.
