ID Attendance Scanner — Attendance at the speed of a scan.

Update ID Attendance Scanner

Two paths. Most teachers only need Path 1.

Download updateJump to Path 2

Primary button = easy updater (Mac + Windows). Do this: Reload. Don’t: Remove.

Path 1 — Normal update (preferred)

License usually stays. You should not need to paste your key again.

  1. Download the easy updater (button above) — not a full versioned zip.
  2. Optional: open UPDATE.html in the unzipped folder for picture-simple steps.
  3. Double-click CLICK HERE TO UPDATE.
    Mac: 00-CLICK HERE TO UPDATE (Mac).command
    Windows: 00-CLICK HERE TO UPDATE (PC).bat
  4. A folder picker always opens. Pick the folder under chrome://extensions → Details → Loaded from. Wrong folder = refused.
  5. Click Reload once on chrome://extensions.
  6. Done.

Do this: Reload.
Don’t: Remove.

Mac blocked the updater? (Sequoia / macOS 15+)

Newer Macs often show only Move to Trash and Done — there is no Open button. Right-click → Open can fail the same way. Do not trash the file.

  1. Click Done (not Move to Trash).
  2. Open System Settings → Privacy & Security.
  3. Scroll down to the security messages. Click Open Anyway for 00-CLICK HERE TO UPDATE (Mac).command (or 00-FIX MAC PERMISSIONS FIRST.command).
  4. Confirm Open when asked, then run the updater again.

Optional: in the unzipped folder, double-click 00-FIX-MAC-PERMISSIONS.command first (clears quarantine on that folder). Sometimes works after you use Open Anyway once.

Fallback — paste in Terminal (Applications → Utilities → Terminal). Change Downloads to Desktop if that is where you unzipped:

xattr -cr ~/Downloads/id-attendance-scanner-easy-updater && open ~/Downloads/id-attendance-scanner-easy-updater/00-CLICK\ HERE\ TO\ UPDATE\ \(Mac\).command

Path 2 — License breaks / “already used” / full reinstall

  1. Open Settings → Your license.
  2. Copy your license key (write it down or paste into Notes).
  3. Click Release this computer → confirm.
  4. Then do Path 1. Or if you already removed the extension: install the new folder once.
  5. Open Settings → paste key → Activate license.
  6. Done. John does not need to reset seats.

Don’t

  • Don’t click Remove (unless Path 2 already told you to reinstall)
  • Don’t pick a different folder than the one under Loaded from
