Biometric Bypass — Fingerprint & Retina Spoof

QBCore/QBox two-stage biometric bypass: spoof a fingerprint then a retina scan, each gated by a server-checked spoof item, before the vault door opens server-side.

NON-TESTÉ — the reference Lua is syntax-validated, not run in a live FiveM server. Adapt and test on your own dev server before shipping.

Description

A two-stage biometric vault bypass: the player spoofs a fingerprint, then a retina scan, each gated by a server-verified spoof item, and only the server opens the door once both stages pass in order. Servers buy it because biometric two-factor is a rare premium mechanic versus the usual keypad or lockpick minigame.

Known Failure Modes & Corrective Prompt

  • Client-tracked stages — keeping the passed-stage flag on the client lets a player fire biometric:retina first and skip the fingerprint; track order in a server table keyed by source.
  • Client door open — freezing/unlocking via a client state bag is forgeable; only the server should emit biometric:open.
  • Anim before load — the scan loop never animates without RequestAnimDict + the HasAnimDictLoaded wait.
  • Item desync — checking the spoof items client-side lets an inventory-less player pass; verify on the server.

Corrective re-prompt: Move the stage-order check into the server: keep stagePassed[src] server-side, require it true inside biometric:retina, and emit biometric:open only from the server after both GetItemByName checks succeed and both spoof items are removed.

Framework Integration

  • ESX: swap to getInventoryItem/removeInventoryItem and esx:showNotification; keep the stagePassed table keyed by source.
  • QBCore: exports['qb-core']:GetCoreObject(), Player.Functions.GetItemByName/RemoveItem, QBCore.Functions.Notify; pair with qb-doorlock.
  • QBox: use exports.qbx_core + exports.ox_inventory:GetItem/RemoveItem; bind the vault to an ox_doorlock group opened from the server.

Profit Potential

$250–$3500/mo on Tebex (expected ~$900). [INFERRED] priced within the $50-389 script band against the signal-scraper tebex_snapshot corpus (n=100, median seller $11.85K/mo), scaled for a rising premium-differentiator niche.

Trend Signal

↗ rising — strategy: Niche pick: biometric spoofing is rare vs keypad/lockpick; a premium differentiator.

Sales Angle

Position as a premium vault upgrade — true two-factor biometric instead of the same keypad minigame on every server. Recommended Tebex price $189.
