# Paradigmas de integración

## Semiintegrado <a href="#semi-integrated" id="semi-integrated"></a>

El dispositivo de pago contiene una aplicación de pago completa que se integra con un sistema ECR/POS externo y gestiona todas las interacciones con el host. El SDK de pagos está integrado en el sistema ECR/POS.

```
actor "Cashier"

component "BYOD\n" as byod <<device>> {
  rectangle "POS"
  rectangle "PSDK" as PSDK <<highlight>> {
    rectangle "Payment App\nProtocol Adapter" as ProtocolAdapter <<highlight>>
  }

component "POI\n" as POI <<device>> {

{% @plantuml/diagram content="    @startuml

actor "Cashier"

component "BYOD\n" as byod <<device>> {

  ProtocolAdapter <<-r->> PaymentApp

actor "Customer"

PaymentApp <<-d->> Host

@enduml" %}
```

## Integrado delgado <a href="#slim-integrated" id="slim-integrated"></a>

En el modelo integrado delgado, compatible solo con el terminal Android, la aplicación de pago ya no se comunica directamente con el host, sino que envía un evento de transacción para la autorización/finalización del host a la aplicación POS, que gestiona las interacciones con el host.

{% @plantuml/diagram content="        @startuml
scale 300 width
scale 300 height

```
    component "Retailer ECR System\n" as ECR <<device>> #Ivory {
      rectangle "POS" #LightYellow {
        rectangle "Cross-Platform PSDK" #LightSkyBlue {
          rectangle "Payment Adapter" as PA
        }
      }
    }

    cloud "Payment Host" as HOST #ivory
    PA <<-d->> HOST

    component "Engage Payment Device\n" as Engage <<device>> 

    Engage -[hidden]> ECR
    hide Engage

    component "Android Payment Device\n" as Android <<device>> #Ivory {
      rectangle "POS Application" as POSAPP {
        rectangle "PSDK" as PSDKAND #LightSkyBlue
      }
      rectangle "Android Payment\nApplication" as AndroidAPP
