No.
The person sending you money doesn’t need to have a Común account or download the app. It can all be done through the web page.
They just need to:
Open the app, your payment link or scan your QR code.
Enter their U.S. personal debit card (no credit or prepaid cards without funds).
Verify their phone number via a security code sent by SMS.
Create a passcode to confirm future payments.
Confirm the amount to send.
Once the payment is completed, you’ll receive the money instantly in your Común account.
💡 Important:
The sender doesn’t register but must verify identity for security.
