The Wallet allows you to send documents to a single user or to a list of recipients. Only authorized recipients can view and download the attached document or file.
After uploading a document to the Wallet, you can send it to a single phone number or to a user list. Simply include the document ID in the message or campaign using the following format: id_NN, where NN is the document ID found in the Wallet.
How Security Works
When a user receives a document download link, a verification session begins to ensure that only that specific person can access the file. No one else will be able to view the content.
The recipient’s phone number is automatically authorized for access.
After receiving the download link, the user must enter an OTP code received via SMS. Once the correct OTP is entered, the user’s IP address is authorized to download the document.
An unauthorized user, even if they know the link or the document ID, cannot view the file. They would need to enter their own phone number, which, since it isn’t authorized—will not receive an OTP. Only numbers explicitly enabled to access that specific document can receive the code.
Example – Authorized User
1. From the Wallet panel, you send a document via SMS to 340 340 340, which is automatically authorized to access it.
2. The user clicks the download link. They receive an SMS asking them to enter their phone number. They enter it and confirm. After confirming, they receive an OTP via SMS and are shown a page where they can enter the code.
3. The user enters the OTP correctly and the document is displayed.
4. Once the OTP is verified, the user’s IP address is added to a whitelist: only that specific IP is allowed by our firewall to access the document. Any other IP is blocked.
The Wallet logs all data and timestamps related to document access, including the signature if required.
Why Not Use WhatsApp or Email
Sending sensitive documents through WhatsApp is a bad idea: files are scanned and archived by AI systems. In general, sensitive documents should never be shared through traditional channels, including email.
Documents sent through the Wallet cannot be accessed under any circumstances, even in the case of lawful interception.
Example – Unauthorized User
Suppose someone knows the document ID.
1. They open the document link and enter the phone number 333 333 333.
2. Since this number is not authorized, it does not receive an OTP, and the corresponding IP address cannot download the document.
Even if your Internet traffic is being intercepted, the document remains protected: our firewall only allows data packets to pass to the IP address that has successfully entered the OTP. An IP address remains authorized for approximately 30 minutes after the OTP is validated.
