Secure. Orchestrate. Innovate.

Powerful transaction processing, on your terms

KAL’s card-acquiring KTH host system drives ATMs, kiosks and POS networks of all sizes. It is a robust and future-ready alternative to conventional host systems, enabling new functionality and rapid changes to be developed with ease. KTH delivers cost reductions along with a superior transaction set. It also increases banks’ abilities to differentiate in the market and enhance the customer experience.


Robust by design

Engineered for resilience

KTH has exceptional availability and performance – rigorously tested, fault-tolerant software that delivers maximum uptime.

Engineered for scalability

With a micro-services software architecture, KTH scales easily by running in a virtualized environment with no limit to the number of servers that can be deployed.

Engineered for security

KTH supports all major security standards such as TLS for communications, TR34/31 for key management, EMV for cards, HSMs for PINs and PCI for overall security.

Innovative banking services

Support for new transaction types

Alongside supporting all traditional ATM transaction types, KTH can orchestrate and create new self-service transactions using any API, web service or bus interface the bank has on its IT infrastructure.

KTH supports new transaction types

Built for flexibility and control

Manage your development cycle

Pre-built components and configurable core code for accelerated software development. The KTH Design Studio is included as standard and is similar to KAL’s K3A development environment.

Customize without compromise

User-friendly and designed to facilitate banks’ own customizations. Updates to the core software from KAL are backwards compatible and do not break your customizations.

Optimize your time to market

KTH fits into an Agile or DevOps environment allowing banks to develop and deploy quickly, while keeping ATMs increasingly relevant and engaging for customers.

Boost operational efficiency

Reduce your IT expenditure

KTH runs in a low-cost hardware environment on virtual servers in the cloud or OnPrem – helping banks reduce total cost of ownership.
