## How do I set up an NFC tag to automatically send a WhatsApp message?

To set up an NFC tag that launches a WhatsApp message, you need a compatible phone (Android recommended), an NFC tag (like Taproo's Business WhatsApp Tap NFC Sticker), and a supported app. You cannot send a WhatsApp message completely automatically – a WhatsApp chat with the intended recipient and pre-filled message will open, but the user must tap Send due to WhatsApp’s security controls.

**Quick answer:**
- Use the [Business WhatsApp Tap NFC Sticker](/shop/whatsapp-nfc-sticker) from £6.99 for reliable WhatsApp use.
- Program your tag with a WhatsApp URL (e.g., `https://wa.me/447123456789?text=Your+Message`).
- Android phones allow writing NFC tags directly using the free NFC Tools app. iPhones can read but have limited automation.
- After tapping, the recipient’s WhatsApp opens with the message pre-filled—final Send must be tapped manually.

### Step-by-step setup: Android
1. Buy a suitable NFC tag—[Business WhatsApp Tap NFC Sticker](/shop/whatsapp-nfc-sticker), [NTAG213 Wet Inlay NFC Sticker](/shop/ntag213-wet-inlay-sticker), or [NFC Keychain](/shop/nfc-keychain-pla).
2. Install the NFC Tools app.
3. In WhatsApp, find your recipient’s phone number in international format (e.g., 447123456789).
4. Format your WhatsApp URL: 
   `https://wa.me/447123456789?text=Hello%20from%20Taproo`
5. In NFC Tools, select 'Write', choose 'Add a URL', and input your pre-filled WhatsApp link.
6. Tap ‘Write’, then hold your NFC tag to your phone to encode.

### iPhone considerations
- iPhones can use the Shortcuts app to automate opening WhatsApp but cannot pre-fill and send messages in one step.
- You can encode a WhatsApp chat URL, which will open the chat, but iOS imposes automation limits.

## FAQs

### Can an NFC tag send a WhatsApp message automatically without user interaction?
No. Security limits mean the tag can open WhatsApp with a pre-filled message, but you must tap Send on your phone. This applies to both Android and iOS.

### Does this work on iPhones as well as Android?
iPhones can open WhatsApp chats via NFC, but Apple does not let third-party apps pre-fill messages within WhatsApp, so functionality is more limited than on Android.

### Can I update the WhatsApp message on my NFC tag later?
If you use a Taproo dynamic tag/page, you can change the linked WhatsApp number or message at any time via your Taproo dashboard, rather than rewriting the tag physically.  Static tags (encoded directly with a URL) need to be re-written.

### What’s the format of the WhatsApp link I need?
Use `https://wa.me/<number>?text=<urlencoded message>`. Example: `https://wa.me/447123456789?text=Hello%20from%20Taproo`.

### Which Taproo NFC tags work best for this purpose?
The [Business WhatsApp Tap NFC Sticker](/shop/whatsapp-nfc-sticker) is optimised for WhatsApp and is easy to set up. General-use tags like the [NTAG213 Wet Inlay NFC Sticker](/shop/ntag213-wet-inlay-sticker) and [NFC Keychain](/shop/nfc-keychain-pla) also work for WhatsApp actions.
