NoteVault: Banknote Identifier

An old bill in a drawer. A note from a trip abroad. A serial number that looks a little too neat. NoteVault helps you discover the paper money in your hands, starting with a photo of each side.

IDENTIFY BOTH SIDES
Photograph the front, add the back if you like, or choose photos from your gallery. AI reads the design, lettering and printed details to suggest the country, denomination, series or year, issuer, signatures and catalog reference.

SERIAL NUMBER INTELLIGENCE
NoteVault checks the serial for patterns collectors look for: ladders, radars, solids, repeaters, binaries, low numbers and star notes. If the photo misreads a character, correct it and the checks update instantly.

CONDITION AND VALUE
See a photo-based condition estimate on the 70-point grading scale, with what was noticed on the paper. When enough evidence is available, see an estimated value range and the reason behind it. When it isn't, NoteVault says so instead of guessing. Similar images from the web help you compare.

YOUR COLLECTION
Save notes with both photos, mark favorites and search by country, year or serial number. Your five most recent identifications stay one tap away. Your collection is stored on your device.

LEARN AS YOU COLLECT
Read 30 short guides on condition, storage, serial numbers and better photos, in English and Vietnamese. The app itself is available in 28 languages.

Identification requires an internet connection. AI can make mistakes: condition is a photo-based estimate, not a certified grade, and values are estimates, not professional appraisals. Verify before you buy or sell.
