How It Works

When a customer tries to log in, complete a booking, or confirm an account change, your system triggers a one-time passcode through SendMeService. A unique code is sent to the customer's mobile number. The customer enters the code, and access is granted. The code expires within a short window so it cannot be reused. Your dashboard records every verification attempt so you have a full audit trail.

STEP 1

Trigger the code

Your system calls SendMeService when a customer needs to verify. A unique code is generated instantly.

STEP 2

Customer receives it

The code arrives on the customer's phone within seconds, clearly branded from your business.

STEP 3

Access granted

The customer enters the code. If it matches and hasn't expired, access is granted. The event is logged.

Where It Makes a Difference

Real scenarios where one-time code (OTP) verification protects hospitality and retail businesses.

Block Fake Bookings

A hotel's online booking portal sends a 6-digit code before confirming a reservation, blocking bot-submitted fake bookings.

Loyalty App Verification

A restaurant loyalty app uses one-time login codes (OTP) to verify every new account, preventing duplicate profiles and fraudulent points claims.

High-Value Order Protection

A retail e-commerce store sends a passcode before processing a high-value order, reducing chargebacks.
