Heres what privacy-savvy consumers should understand about NFC notices and RFID tags

In your home: Set phone on vibrate, connect to speakers, automate common phone tasks such as calling Mom (or as I call my own, Nanay, which is Tagalog for mama).

Marketing: Embed a link in the NFC tag to take users to your site, landing page, download link, and more. NFC tags can be made use of much like QR codes are used for marketing campaigns.

Simply like with e-mail, DMs, SMS, and QR codes, if you get an unanticipated link from an unknown source, do not click or tap it..

A couple of weeks earlier, I had a #TreatYoSelf minute and bought myself a sweet wallet. Over the course of weekend, I discovered that I was getting NFC notices and could not figure out what was triggering them.
Turns out, it was a marketing link from the wallet producer. After some research study, I discovered that, in 2016, the business started using RFID tags in an effort to confirm the authenticity of their items and battle fakes.
Then I realized that theres no other way to switch off the NFC reader on iPhones. That means anytime my phone is near my wallet, I get a notification from the wallet brand name to visit their website.
Its not possible to have a notice pop up every time my phone is near my wallet. I did a deep dive into NFC notices, RFID tags, and what to do about them.
