How to program a NTAG215 NFC Tag

Hi! Did you just acquire a NTAG215 NFC tag? Very cool. Maybe you scanned it and it brought you here. Here's how to edit the content on the tag to make it do what you want. 

Easy Steps

  • Download an NFC writing app on a smartphone like this one for Android or this one for iPhone. I assume you might have this app already if you're reading this tag. Done
  • Decide what type of data you want to save. If you picked up more than one of the NFC tags, you may have a variety of data saved to them like the ones below:
    • Plain text
    • URL/URI
    • Link to a search
    • Social networks
    • Video
    • File
    • Application
    • Mail
    • Contact
    • Phone number
    • SMS
    • Location
    • Address
    • Proximity search
    • Street View
    • Emergency info
    • Bitcoin address
    • Bluetooth connection
    • WiFi network settings
    • other custom fields
  • Make sure if you select the correct format to make it easier to scan, save the write data, and re-scan the tag.
  • Switch back to the read function and test your tag!

Next Method

The above method doesn't cover making everything, such as Amiibo tags. For that you'll need a more advanced method of writing.

There are plenty of other devices that can read and write NFC tags. The Proxmark is a powerful and versatile tool used for RFID and NFC research and security testing. It can also sniff or capture the communication between an RFID reader and a tag. This helps in understanding how the system communicates and in identifying potential vulnerabilities. Advanced users can program the Proxmark with their own firmware or scripts to perform specific tasks, making it highly versatile for various research and testing purposes. However, it's expensive and an online purchase away. You can download and easy app now, and that'll be just fine.

I think if you're really interested in the topic you should invest in the Proxmark. It's enriching to understand how it works instead of just using the apps. As mentioned above there are more advanced features too, which can't otherwise be achieved. Also, there are other hardware devices that are similar, this is just the hardware I prefer. 

Have fun!

2023 Resolutions

Welcome to my New Year's Resolutions! I feel a little vulnerable sharing my goals publicly and auditing if I failed or succeeded over the year.  My 2023 Resolutions 1) HACK THE PLANET! 2) Upload to WiGLE every month 3) Post to the blog at least once a month 4) Continue to follow and maintain my vision board. Don't judge me! I thought they were cheesy and weird, but it's been so effective. I made a blog post about it already, but just as a refresher my current board is below. A vision board is almost a resolution list in of itself. These are all the things I want to achieve in the near future.  5) Pass the HAM radio exam 6) Continue in content creation and make articles or a podcast Let's go over what my resolutions where last year: My 2022 Resolutions 1) Make it to 500,000 unique wifi networks I made it in November!

Remove data from Data Brokers

 If you have a little change from your tax return, I have a suggestion on where you should spend it this year. This is not sponsored, not an advertisement, and I do not benefit from these companies. I paid for these services out of pocket on my own. Okay. We all know how scary OSINT can be, being able to look up public information such as age and home address. We hand over this information readily when we use certain products and services. Some of this information is also kept at a criminal level, such as criminal record lookups.  That's not the only information we hand over, we are tracked and have our data collected every day through data brokers. They profit off of our identities selling it back to one another constantly.  There are services now that will automate the removal of your data from data brokers. I found Aura and Incogni when promoted online. Both of them had a referral code, but also a standard discount for an annual subscription instead of monthly. At the time of wr
