Recently-issued grade reports (Certificado de Concentración de Notas) from Universidad San Sebastián in Chile can be verified online at http://certificados.uss.cl.
The verification requires the RUT number (numerals only) and the Número de Folio, both found on the document. Scanning the QR code on the document arrives at the same results.
The verification brings up an overview of the student's enrollment, including their status, which can confirm if the student has graduated. It does not include a copy of the grade report.
