# iOS framework

The iOS framework integration steps help you to integrate payment acceptance into your iOS app.

{% stepper %}
{% step %}
Integrating the iOS framework connects your app to the VP3300 mobile card reader using Apple’s Bluetooth implementation in the IDTech framework.
{% endstep %}

{% step %}
The framework sends messages to your iOS app that guide customers during their interaction with the card reader in a transaction.
{% endstep %}

{% step %}
The iOS framework secures the card data after a successful read and sends it to the Xplor Pay server.
{% endstep %}

{% step %}
The iOS framework packages the secured card data as an encrypted JSON Web Token (JWT) and sends it to your app through a callback function. 
{% endstep %}

{% step %}
You can send the encrypted JSON Web Token (JWT) to the mobile gateway to process the payment.
{% endstep %}
{% endstepper %}

{% hint style="info" %}
The iOS framework uses the [IDTech iOS framework](https://idtechproducts.atlassian.net/wiki/spaces/KB/pages/71754539/Integrating+Applications+for+Multiple+ID+TECH+SDKs#iOS-SDK) to read card data on the VP3300 mobile card reader. You can continue to use other [IDTech frameworks](https://idtechproducts.atlassian.net/wiki/spaces/KB/pages/71703365/iOS+Development+-+Home) if your requirements don’t meet with the recommended workflow.
{% endhint %}
