# Kiosk Flow

Customers interacting with the kiosk navigate through a sequence of pages known as the "**kiosk's flow**".\
\
The process starts by determining if the customer wants to check into a pre-scheduled appointment or join the queue for walk-in services.

The following diagram depicts the flow steps:

## The Prerequisites Flow

Depending on the selected service's Prerequisite configuration, the kiosk may ask the customer for a phone number, email, or customer ID.

### Require Customer ID

For walk-in services that require a customer ID, the kiosk will prompt the customer for identification.

Depending on the "Customers" table self-authentication configuration, the portal will ask for key and validation fields or a customer ID and OTP.

{% hint style="warning" %}
Implementing One-Time Password (OTP) authentication in kiosk systems can lead to longer transaction times as users wait to receive and enter their OTP. This could increase wait times and potential queues at the kiosk, impacting the overall user experience.
{% endhint %}

To learn how to configure customer self-authentication, see:

{% endcontent-ref %}

## **Data Collection**

If the selected service's category configures one or more **required** fields, the kiosk will ask the customer to provide values for these fields.
