A T2 voucher comes from the Knowledge Fee payment. If you hold a T1 voucher (Access Fee), please go to the
Knowledge Library.
📖 Voucher Rules (tap to view)
1. Validity is decided only by the countdown: T1 = 3 hours / T2 = 72 hours. When the countdown ends the voucher is void, no refund. 2. Unlimited re-entry while the countdown runs: closing the page, losing connection or powering off does NOT void the voucher — come back and enter the voucher number to go straight in (remembered on this device). 3. Use completes the mission: a T2 voucher is used to fetch the pickup key (token) of a file — one key per file per voucher, shown in plaintext up to 3 times (scan #1 = lodge the pickup request, scan #2 = receive the file handed over at the window, 3rd display = spare); the key burns after the 3rd display. 4. Voluntary exit = immediate void: tapping [Exit Choice] inside the library and confirming twice burns the voucher immediately — no refund, no recovery. Recorded as a voluntary forfeiture, clearly distinguished from a failure/interruption. 5. Re-purchase after exit: an exited voucher does not block you from paying again at any time.
