Aureus - NFC Reader & Encoder

Aureus turns your phone into a professional NFC encoding studio. WRITE ANYTHING Encode website links, Wi-Fi credentials, contact cards, plain text, phone numbers, emails, and app links to any NFC tag with a single tap. Every write is verified with an automatic read-back, so you know it worked before you walk away. BATCH AND REUSE Building more than one tag? Save a Profile or Template once and reuse it across an entire batch — ideal for product packaging, event badges, retail displays, or business card tags. Batch jobs track progress so nothing gets missed. LOCK IT DOWN When a tag is ready for the real world, permanently lock it read-only, or protect it with a password, directly from the app. These are clearly labeled, deliberate actions — Aureus always confirms before doing anything irreversible to a physical tag. SECURE PROVISIONING For anti-counterfeit and access-control use cases, Aureus supports DESFire EV2 and NTAG 424 DNA secure provisioning, with real cryptographic key management handled on-device. PLANS THAT FIT Start free. Upgrade to Pro or Business for higher batch limits, secure provisioning, and priority support — or go Lifetime for a one-time payment, no subscription. All billing is handled securely through Google Play. Your tag content stays on your device — Aureus is built local-first, and never reads or stores what you write to a tag.
