Cart Validation through OTP (One Time Password) Show more

The OTP on Cart app enhances the security of online shopping by validating carts with a One-Time Password (OTP) before checkout, ensuring that the purchaser is the account holder. Integrated with Twilio and MSG91 SMS gateways, the app reliably sends OTPs to customers' registered mobile numbers. Retailers just need to enter their Twilio or MSG91 account credentials and token keys in the app's configuration section to activate the service. Customers enjoy a secure and streamlined checkout experience, reducing the likelihood of fraudulent transactions. This app is ideal for online businesses seeking to add an extra layer of protection to their purchase process. The setup process is straightforward, but users need to have an existing Twilio or MSG91 account to use these features. Overall, the OTP on Cart app provides both shop owners and customers with peace of mind during online transactions.

Helps merchants to authenticate clients using SMS verification Show more

FraudLabs Pro SMS Verification is a powerful tool designed to ensure that a buyer is the legitimate owner of a given phone number by utilizing an SMS verification loop. The application sends a One-Time Passcode (OTP) to the buyer's mobile number, which they must enter correctly for identity verification. This process creates a checkpoint at the view-cart page, effectively filtering out non-serious buyers and authenticating genuine purchasers. By confirming the buyer's phone number ownership, the app helps minimize payment fraud and prevent fraudsters from spoofing phone numbers. Integrating this verification step before checkout can also significantly reduce order refunds and chargebacks. As a bonus, first-time installations are granted 10 free SMS credits to get started easily with this security enhancement.
