Hearing the money arrive
The part that does the work at a busy counter.
- A chime, then the amount spoken aloud in English. Numbers are spelled out in full so they survive counter noise.
- Optionally speaks the sender's name, and announces outgoing payments too.
- Separate volume sliders for the chime and the voice, each with its own preview button.
- Can play through the alarm channel, so a phone left on silent still announces money. There is a volume boost for the same reason.
- Quiet hours, with start and end times you pick.
- A heads-up notification alongside the sound, for when the shop is loud anyway.
