Reverse OTP over WhatsApp

Say hi.
You're verified.

Your users send one WhatsApp message instead of typing a code. HiVouch matches it to their number in about three seconds. No SMS bills, nothing to intercept, and you pay only when a user is verified.

How it works

The message travels the other way

1
Tap
Your user taps "Say hi on WhatsApp". WhatsApp opens with the greeting already written.
2
Send
They press send. The greeting carries a one-time token tied to their session.
3
Vouched
HiVouch matches the token to the sender's number, replies "Vouched", and calls your webhook.

Compared with SMS

Cheaper than SMS, and nothing to type

HiVouch compared with SMS OTP
	SMS OTP (local route)	HiVouch
Cost per verified user, Egypt	$0.012-0.026	$0.003-0.007
What the user does	Waits, copies and types 6 digits	Taps, then presses send
Failed and resent attempts	You pay for every SMS sent	Free
SMS-pumping fraud	Exposed	Not possible: the user sends
What it proves	Someone could read the code	The SIM itself sent the message

SMS range from public SMS A2P package prices (2026) at 1.1 messages per verified user. HiVouch range from Egypt package prices.
