SerialDex vs NoteLens

Every banknote has a serial number. Most are ordinary. A few are worth keeping - and you are probably carrying one without knowing it. Point your camera at a banknote. SerialDex reads the serial number, checks it against the patterns collectors actually look for, and tells you straight away what you found. WHAT IT LOOKS FOR Radars that read the same backwards. Solids made of a single repeated digit. Ladders climbing in sequence. Low serials, binaries, repeaters, million-marks. Every match is sorted into one of five tiers, from Common to Legendary, with an explanation of why the pattern matters. SIX CURRENCIES, NOT JUST DOLLARS Polish złoty, US dollar, euro, Japanese yen, British pound and Canadian dollar - each with its own serial format and its own pattern set. A Polish note is two letters and seven digits; a dollar is eight digits with a series letter. Most tools handle one of these. SerialDex handles all six. THREE WAYS IN Scan with the camera, import a photo you already took, or type the serial by hand. Whichever you use, the answer is the same. A COLLECTION THAT KEEPS SCORE Every checked banknote lands in your collection with its pattern, tier and date. Rare finds earn experience. Experience raises your level, and your level unlocks titles - each one raising how many scans you get per day and how many shields you carry to undo a mistaken read. NO ACCOUNT. NO INTERNET. NO TRACKING. SerialDex has no servers and makes no network requests at all. Your collection, your profile and your settings never leave the phone. There is nothing to sign up for and nothing to opt out of. ABOUT THE AMOUNTS SerialDex shows a collector value range for the patterns it recognises. Treat it as an indication of how much interest a pattern attracts - not as a market valuation, an appraisal or an offer. What a note actually sells for depends on its condition, the buyer and the day. Please do not base a purchase or a sale on these numbers. Available in English and Polish. Light and dark. Blue, purple or mint.

NoteLens helps you work out which banknote you're holding, and keeps a private record of the notes you collect. IDENTIFY A NOTE FROM A PHOTO Photograph a banknote, or pick a photo you already have. NoteLens reads what it can see: country, currency, denomination, year, series, issuing authority, material, serial number and design. Each detail is labelled with where it came from. Anything the photo doesn't show is marked "Not visible" rather than guessed, and NoteLens tells you when a photo is too dark or blurred to read well. BUILD YOUR COLLECTION Save the notes you identify to a collection stored on your device. Add your own grade, purchase price and date, where you found a note, and notes of your own. Search, filter by country, condition or year, mark favourites, and compare notes side by side. LEARN AS YOU GO A built-in reference guide covers the anatomy of a banknote, security features, watermarks and threads, serial numbers, grading, materials, storage and getting started. It works offline. CONVERT CURRENCIES See what a note's face value is worth today in another currency, with exchange rates updated daily. PRIVATE BY DESIGN • No account, no sign-in and no ads. • Your collection stays on your device. • A photo leaves your phone only when you ask for an identification, and its location and camera details are removed first. • Anonymous usage and crash reports stay off unless you choose to share them. GOOD TO KNOW Identification is an AI estimate made from a photo. NoteLens can't confirm that a note is genuine, and it doesn't give market values or professional grades. For anything valuable, ask a dealer or grading service. Identification needs an internet connection.
