Offline prize matching and e-invoice scanning available. Provides Republic of China Uniform Invoice winning numbers and e-invoice functionality. Directly compare numbers on the invoice, or use the prize matching machine to enter the last 3 digits for prize matching. You can also scan the QR code on the left side of the e-invoice proof to match prizes and view transaction details. The program automatically updates after the draw on the 25th of each odd-numbered month.

【Prize Matching Machine】 You can quickly enter the last 3 digits of the invoice. If the last 3 digits of the first prize match, you have won a sixth prize. Your phone will vibrate to notify you and display the complete first prize number for comparison with other prizes.

If the last 3 digits of the grand prize match, your phone will vibrate and provide a voice prompt (voice prompt can be selected in [Settings]). The complete grand prize number will be displayed for comparison with the grand prize.

【E-invoice】 Use your phone's camera to scan the invoice paper. The system will automatically check the winning numbers and save the QR code or barcode after scanning. It is recommended to use a phone with at least 8 megapixels and a clear barcode scanner.

[Number Slip] Lists the winning numbers for the last two draws of the uniform invoice (internet access required).

[Scanning Record] Scanning the QR code on the left side of the electronic invoice will record the information on your phone. Invoices that haven't been drawn yet can be scanned first; after the draw, you can directly check if you've won and view the transaction details (the time when you can access the transaction details may vary).

[Month] You can select the months where you can still claim your prize. Check all four months at once; no need to organize a bunch of invoices by month, just use them directly for the prize check.
