MagicNFC, the One-Tap NFC Tag Programmer

Field notes

The page describes a three-step flow: select a payload, enter its destination, and hold the phone near a tag. It focuses on standard NDEF Type 2 hardware, including NTAG213 with 144 bytes of user memory and NTAG215 with 504 bytes. A capacity validator is shown checking whether a payload will fit before writing, while saved templates are described as a way to reuse configurations across multiple tags.
