We’ve spent the last seven years building NFC apps for iPhone and Android. Along the way we’ve answered the same questions over and over in App Store reviews, support emails, and forum threads - about tag types, writing NFC from an iPhone, the difference between NFC and RFID, why your condo door won’t open, why your contact card sometimes won’t save. So we’re starting a blog to put the answers somewhere stable, searchable, and free.
What you’ll find here
Practical guides - step-by-step posts on writing NFC tags, decoding QR codes, scanning documents, and getting the most out of NFC.cool Tools and Business Card.
Honest comparisons - head-to-head looks at digital business card apps, NFC tag formats, and adjacent tools. No sponsorships, no affiliate framing.
Industry deep dives - how doctors, real-estate agents, consultants, and conference organizers are actually using digital business cards in the wild.
Technical insights - NFC standards, NDEF records, the EU Digital Product Passport, App Clips, Live Activities, and whatever else lands on our desk.
Why we’re doing this
Since 2019, NFC.cool apps have been used by millions of people across iOS and Android. Every one of those installs has taught us something about how NFC actually performs in the wild - which tags last, which interactions stick, which features matter, which ones are gimmicks. The blog is where that learning gets written down.
