Memory Layout

The TigerTag memory structure follows the layout of NTAG213-compatible RFID tags. Each memory page consists of 4 bytes. The layout below defines how data is distributed across pages 4 to 39, with key identifiers, material information, print parameters, metadata, and a digital signature. This memory format ensures cross-compatibility with slicing software, printer firmware, and cloud services reading encoded spool metadata.
