Someone says they paid. Their screen says sent. You still don't know.
LunaBell turns a phone into a Nimiq payment soundbox. Create a charge, show the QR, put the phone down. When the payment actually settles on-chain, the bell rings and speaks how much arrived.
Runs inside Nimiq Pay. Works in any browser for a look around.
Someone shows you a payment screen, you hand over the goods, nothing ever arrives. India answered this in hardware, and merchants bought it by the million.

“Before sound boxes, people were using apps to create fake payment receipts. I got conned a few times.”a merchant, quoted by Rest of World, 4 April 2023
A charge is one object: amount, reason, and a tag derived from it. It lives in its own link, so there is no account and no database.
Prop the phone up as a counter code, or drop the link in a chat. Whoever pays does it from their own wallet, straight to yours.
It rings only for that tag, that exact amount, that recipient, and only after the charge was made. Hands stay full, eyes stay up.
Every open re-reads the chain. The confirmation count climbs while you watch it. No screenshot can do that.
The numbers on the right are read live from Nimiq mainnet, right now, in your browser.
A struck bell, then the amount in the language Nimiq Pay is already set to. Serve the next person without checking a screen.
Matched on tag, exact amount, recipient and block window. A dust transfer or a replayed old payment cannot set it off.
Forward it into the argument. It re-reads the chain on every open, so its confirmation count keeps climbing.
Payment goes wallet to wallet. No custody, no deposits, no account, no database. The charge lives in its own link.
Amounts announced in NIM or the local currency, with the luna count shown for anyone who wants the exact figure.
Every matching rule is in the repo with tests that assert the bell stays silent when it should.
Or in the group chat where someone still owes you. Same bell, same receipt.
