Download on the App StoreA giant green or red screen with the exact age, readable at arm's length in a dark doorway. Under age? See "turns 21 in 43 days" instead of doing date math at midnight.
License barcode mode reads the PDF417 barcode on US and Canadian licenses and ID cards. Passport / ID mode reads the MRZ lines on a passport photo page, or on the back of an EU national ID card or residence permit.
Choose 16, 18, 19, 20, 21 or 25 (Challenge 25) to match your jurisdiction or door policy.
An expired document turns the screen red even when the guest is of age.
Light toggle, 2x zoom and near-range focus tuned for small, worn barcodes. Fully offline.
Flag a patron once from the result screen. A star banner or a banned alert, with your note, appears every time that ID is scanned again. Stored only on your device.
