32. A computerized system comprising: one or more processors; and one or more computer storage media storing computer-usable instructions that, when used by the one or more processors, cause the one or more processors to: receive a camera scan corresponding to a QR code displayed by another computing device, the QR code being displayed in conjunction with a digital document having a signature field and stored on the other computing device; access a URI encoded in the scanned QR code, the URI corresponding to a dynamic application interface, provided by a remote server device, that immediately requests a biometric signature via a touchscreen; communicate the received biometric signature to the remote server device via the dynamic application interface, wherein the remote server device is configured to relay the received biometric signature to the other computing device and cause the other computing device to associate the received biometric signature with the signature field.
