How to Put Your Instagram Link on an NFC Tag

An NFC tag can hold a link to your Instagram, TikTok, website, booking page or anything else with a web address. Once it is written, people just hold their phone near the tag and your link pops up. This guide shows you exactly how to set one up on iPhone and Android using the free NFC Tools app.

What you need

  • An NFC tag. A sticker, card or keychain. Common chips like the NTAG213 work well for a single link.
  • A phone that can write NFC. iPhone 7 or newer on iOS 13 or later, or an Android phone with NFC.
  • The NFC Tools app. It is free and made by wakdev. It is available on the App Store and Google Play.
  • Your link. Copy it before you start so you can paste it in.

A quick note on apps: the people who tap your tag do not need any app, there is no app needed to open the link. Only you need an app, and only to write or change the link. NFC Tools does that on both iPhone and Android.

Step 1: Get your link ready

For Instagram, your link looks like this: https://instagram.com/yourusername. Swap in your actual username. You can also copy it from the share option on your Instagram profile. Most other platforms have a similar share or copy link button.

Check the length. An NTAG213 chip holds 144 bytes, which fits a link of roughly 130 characters. Most profile links are much shorter than that. If yours is long, run it through a link shortener first.

Step 2: Write the link on iPhone

  • Open NFC Tools and tap Write.
  • Tap Add a record.
  • Choose URL / URI. Do not choose Text.
  • Paste your link and tap OK.
  • Tap Write. When the "Ready to Scan" sheet appears, hold the top of your iPhone against the tag.
  • Keep it still until you see a check mark or a success message.

Step 3: Write the link on Android

  • Make sure NFC is on. Open Settings and search for "NFC". The menu name differs by brand.
  • Open NFC Tools and go to the Write tab.
  • Tap Add a record, then URL / URI.
  • Paste your link and tap OK.
  • Tap Write and hold the back of your phone against the tag.
  • Wait for the success message.

The NFC antenna is in a different spot on every Android phone. If nothing happens, slowly move the tag around the back of the phone until it connects.

Step 4: Test it

Lock your phone, wake the screen, and tap the tag. A notification or banner with your link should appear. Tap it and make sure it opens the right page. Then try it on a friend's phone, ideally one of each type.

The mistake that breaks most tags

The record must be only the link, starting with https://. If there is any text in front of it, such as "My Instagram: https://...", the phone will not open it as a link. The same happens if you pick a Text record instead of a URL record.

Also check that https:// appears only once. If the app already shows https:// as a prefix, do not type it again. Before writing, look at the record in the list and make sure it reads as one clean web address.

Do not lock the tag

NFC Tools has an option to lock a tag. Locking is permanent. Once a tag is locked, you can never change the link on it again. Unless you are completely sure the link will never change, skip this option. Most chips are rated for a huge number of rewrites (the NTAG213 is rated around 100,000), so there is no reason to lock it to protect the chip.

Troubleshooting

The phone does not react at all

  • Wake the screen first. Phones do not read tags with the screen off.
  • On iPhone, hold the tag near the top edge of the phone, not the middle.
  • On Android, make sure NFC is turned on and try different spots on the back.
  • Get closer. NFC range is only a couple of centimeters.

It works without a case but not with one

Thick, metal or magnetic cases, including cases with built-in magnets or card holders, can block NFC. Try tapping with the case off to confirm, then decide whether to switch cases or tap a different spot.

It reads, but the link does not open

This is almost always the record format. Open NFC Tools, use Read to see what is on the tag, and rewrite it as a single URL record with nothing in front of https://.

Older iPhones

iPhone 7, 8 and X can read tags, but not in the background. Open Control Center and use the NFC Tag Reader, then tap the tag.

What about contact cards and Wi-Fi?

NFC Tools can also write contact details or Wi-Fi login info. Joining Wi-Fi straight from a tag works on Android. On iPhone it does not work the same way, so the more reliable move is to point the tag to a web page that shows your contact info or Wi-Fi details. One web link also works the same on every phone.

Changing your link later

New handle? New website? Just repeat Step 2 or Step 3 with the new link. Writing a new record replaces the old one. No reprinting, no new tag.

Setting up a Spinek

If you are using a Spinek NFC keychain, the steps above are exactly how it works. The chip sits under the four navy signal arcs on the body, so that is the spot to hold against your phone. Every unit is tested and paired before it ships, and you can rewrite it as often as you like with no account and no subscription. There is also a short setup guide on the Spinek pairing page if you want the steps in one place.
