Apollo family releases
The Payter Apollo family of devices is operated by a collection of several smaller applications/components and an operating system (OS), packaged together as a "Build." Not every application or component is changed from one build to the next.
Payter bundles the app containers together, so every app update includes all containers. You can update the apps without updating the platform. In the following table, Size is the full download for each component. An update downloads only the parts that have changed, so it uses much less data.
| Name | Function | Size | |
|---|---|---|---|
| Apollo UI | The application that controls the Apollo user interface. | 5–10 MB | |
| NEXO-FAST | The Payment Application, Secure Payment Processor, and Key & Encryption handling. | 5–10 MB | |
| Host Adapter | Interface with the specific Gateway, Host or Acquirer interface. Includes the Engine, and the specific application for each Gateway. | 80–90 MB | |
| Configuration | The underlying configuration options that control or enable the various other applications. | ||
| SCAP | Specific selected Application interface. Variants include: | 5–10 MB | |
| Scap-psp | Payter Session Protocol (PSP): Local Integration interface | ||
| Scap-autoscan | Autoscan interface | ||
| Scap-mdb | Multi-Drop Bus interface | ||
| Scap-cci | Coffee Credit Interface | ||
| The Cloud Payment Service (CPS) does not have a SCAP, as it is in the cloud. | |||
| Apollo Platform | A Linux Operating system, also known as the Platform or Firmware. | 140–150 MB | |
Apollo family devices have 256 MB of DDR3-800 RAM, plus 8 GB eMMC storage
Release note format
Release notes contain information about each build package and explain the enhancements and issues resolved for each component in the new version.
In January 2026 we amended our Build notation from yyddd to yymmm where mmm is a three-letter month notation. For
example, 26Jan is the build released in January 2026.
Prior to September 2024, we used yyyymmdd notation as well.
