| Term | Definition |
|---|---|
| Class code | An invite-only access code distributed inside the physical yearbook. Required to create an account and view any profile on the class network. One code per class, not per person. |
| Class network | The private web app (e.g. classof26.network) that opens when an NFC tag is tapped. Contains directory, profiles, guestbook, time capsule, superlatives, senior wills, timeline, and playlist. |
| Digital profile | Each graduate's personal page on the class network. Displays their portrait, quote, next chapter, anthem song, guestbook, and time capsule. Accessible only to authenticated class members. |
| Draw Your Face | The onboarding mechanic — instead of uploading a photo, graduates draw a self-portrait on a canvas. The drawing becomes their avatar in both the physical yearbook and the digital profile. |
| Guestbook | A message board on each profile where classmates can leave notes. Messages are visible to all authenticated members. |
| NFC (Near Field Communication) | A short-range wireless technology (1–3 cm) that allows a phone to read data from a small tag when held nearby. Built into every modern smartphone. No app, Bluetooth, or Wi-Fi required. |
| NFC tap icon | A printed symbol (3 curved lines resembling a wave) placed next to each scannable portrait. Tells the reader "hold your phone here." |
| NTAG215 | The NFC chip used for most yearbook tags. 540 bytes of memory, 25mm (or 20mm) diameter, rewritable, ~10 year data retention. The industry standard for NFC stickers. |
| NTAG216 | Larger NFC chip (888 bytes, 30mm) used for the inside back cover time capsule tag. Same read range and compatibility as NTAG215. |
| Onboarding | The one-time process where Eventbuoy sets up the class network, designs print templates, programs NFC tags, and provides the placement guide. Included in the $300 fee. |
| Perfect binding | A binding method where pages are glued to the spine (like a paperback book). The NFC tag sits between two glued pages. Tags must be kept 15mm+ from the spine to avoid glue interference. |
| Saddle-stitch | A binding method where pages are stapled through the fold. NFC tags work fine; still keep 15mm+ from spine. |
| Senior Wills | A yearbook page where graduating seniors "bequeath" things to underclassmen — e.g. a parking spot, a teacher's trust, a hallway shortcut. |
| Sweet spot | The pricing range (100–500 tags) that offers the best balance of per-unit cost and practical yearbook scale. Tags in this range cost $0.97–$1.38 each. |
| Time capsule | A feature where classmates write messages to a graduate's future self. Messages are sealed until a specified reunion year (e.g. 2036). Cannot be read by anyone until that date. |
