# Zen Card

### What is Zen Card? <a href="#what-is-zen-card" id="what-is-zen-card"></a>

**Zen Card** is an innovative NFC-enabled product developed by **Ninety Eight**, designed to bridge your digital identity and your Web3 assets - all in one sleek physical card.

It serves **two main purposes**, depending on how you choose to use it:

1. **E-Card (Digital Business Card)**
   * Create your personal profile (name, username, contact info, and social links).
   * Share your identity instantly - anyone can tap their NFC-enabled phone to your Zen Card and view your profile in a browser.
2. **Hybrid Wallet**
   * Store and manage your crypto assets securely.
   * Combines the **ease of a hot wallet** with the **security of a cold wallet**, ensuring your assets stay protected while remaining accessible.

### Why is Zen Card's Hybrid Wallet Secure? <a href="#why-is-zen-card-secure" id="why-is-zen-card-secure"></a>

Zen Card uses a unique **Split-Key Encryption** design:

* One part of your private key is stored on the **Zen Card**.
* The other part stays securely inside your **smartphone**.

Both parts must be combined to sign a transaction and are automatically destroyed afterward. Even if one device is lost or compromised, your funds remain safe.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.coin98.com/products/physical-cards/zen-card.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
