# TapAI with Authentication

{% hint style="warning" %}
Ixkio recommend using TapAI with authentication NFC tags only to protect usage. 
{% endhint %}

TapAI can be used with standard NFC tags and even QR Codes. However, ixkio strongly recommend using TapAI with authentication (NTAG424) NFC tags only. 

The TapAI feature uses credits which you pay for. The cost of this is very low and we are working on driving the pricing cheaper - but it still costs you money. 

When you use authentication NFC tags, you can configure your ixkio project so that the user must have scanned the NFC tag to access TapAI. 

If you use standard NFC tags or QR codes, then the static link could be shared anywhere on social media. Anyone with the link can then use TapAI. You could have thousands of people asking questions on your product - without access to it.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ixkio.com/modules/tapai/tapai-with-authentication.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
