The SMS Signature tool helps company clients effortlessly review and sign any electronic document in a matter of seconds from anywhere in the world. Our solution is designed to help companies accelerate their remote business deals, reduce costs, save time, and create a customer-friendly experience for the user. A customer that wants to sign a specific document enters his phone number, which is uniquely linked to an advanced electronic signature. In a few seconds, the user receives a text message with a custom 6-digit PIN code as a verification method. Once the code is submitted into the system, the document is automatically signed, enabling all further business procedures. This allows new as well as existing users to open accounts, acquire loans, finalize agreements, and accept commercial offers through a simple text message.
