About
Check every ID at the door in one look. Point the iPhone at a passport or ID card, or at the back of a US or Canadian driving licence. CRDD reads it in a second and fills the screen: green to let them in, red to stop them, amber to check by hand. The age is the biggest thing on the screen, so you can read it from a step away in a dark room. EVERY ID AT THE DOOR • Passports and national ID cards from any country: the machine-readable lines • US and Canadian licences and ID cards: the barcode on the back • UK and EU photocard licences carry no barcode to read: check those by hand • No need to pick the type: CRDD knows what you hold up • Scans on the first try, with the torch for dark doors CHECKS YOU CAN TRUST • Age against your limit: 18, 19, 21 or 25 • Expired documents • Licence format checks for each US state and Canadian province: issuer code, number format, dates, the under-21 layout • Passport and ID card check digits • CRDD says "checks passed" or "check by hand". It never says a plastic card is real when a phone cannot know that. CHIP CHECK Most passports and many ID cards carry a chip. Hold one to the iPhone for a few seconds: CRDD reads the chip, checks the issuing country's digital signature, and shows the photo stored in it. That is real proof that the document is genuine, and that the face in front of you is the one on it. RUN THE DOOR • Ban list: a banned guest turns the screen red the moment they scan, with their photo • VIP list for your regulars • Passback: a warning when the same ID comes back in tonight • Tonight's log: who came in, who was denied and why • Stats: arrivals by hour, the age mix, repeat guests PRIVATE BY DESIGN No account and no cloud. Scans stay on this iPhone, encrypted. CRDD keeps no licence numbers, only a keyed code to spot the same ID again, and it deletes old scans after the days you choose. FREE AND CRDD PRO Every feature is free for 5 scans a night. CRDD Pro takes the limit away: unlimited scans, every night. CRDD Pro is an auto-renewing subscription, weekly or yearly, and can start with a free trial, shown in the app before you buy. Payment is charged to your Apple ID when you confirm the purchase, or when the free trial ends. The subscription renews automatically unless you cancel it at least 24 hours before the end of the current period, and your account is charged for the renewal within the 24 hours before the period ends. You can manage or cancel it in your Apple ID account settings. CRDD helps staff check IDs. It does not replace your own judgement or the law where you work.

Check every ID at the door in one look.
Point the iPhone at a passport or ID card, or at the back of a US or Canadian driving licence. CRDD reads it in a second and fills the screen: green to let them in, red to stop them, amber to check by hand. The age is the biggest thing on the screen, so you can read it from a step away in a dark room.
EVERY ID AT THE DOOR
• Passports and national ID cards from any country: the machine-readable lines
• US and Canadian licences and ID cards: the barcode on the back
• UK and EU photocard licences carry no barcode to read: check those by hand
• No need to pick the type: CRDD knows what you hold up
• Scans on the first try, with the torch for dark doors
CHECKS YOU CAN TRUST
• Age against your limit: 18, 19, 21 or 25
• Expired documents
• Licence format checks for each US state and Canadian province: issuer code, number format, dates, the under-21 layout
• Passport and ID card check digits
• CRDD says "checks passed" or "check by hand". It never says a plastic card is real when a phone cannot know that.
CHIP CHECK
Most passports and many ID cards carry a chip. Hold one to the iPhone for a few seconds: CRDD reads the chip, checks the issuing country's digital signature, and shows the photo stored in it. That is real proof that the document is genuine, and that the face in front of you is the one on it.
RUN THE DOOR
• Ban list: a banned guest turns the screen red the moment they scan, with their photo
• VIP list for your regulars
• Passback: a warning when the same ID comes back in tonight
• Tonight's log: who came in, who was denied and why
• Stats: arrivals by hour, the age mix, repeat guests
