Yes, the document will be available for download 30 days before it is removed. ### What data can be seen in the document? In the signature, your full name will be recorded. In the embedded signing certificate, the last four characters of NRIC will also be embedded in the document. ### Can someone sign on a person's behalf? Yes, if the signer is legally authorised to sign on behalf of another person. The signer would use his own Singpass account to sign, similar to what he would do for wet ink signature. ### Can I sign on Signify without Singpass? No. Singpass is required. This is because the Electronic Transactions Act recognises signatures made using certificates issued by Accredited Certificate Authorities (CA) as [Secure Electronic Signatures](https://www.imda.gov.sg/regulations-and-licensing-listing/electronic-transactions-act-and-regulations/controller-of-certification-authorities/accredited-cas-in-singapore). Sign with Singpass uses signing certificates issued by an accredited CA, Assurity. ### How long will documents be available for download for signee? If the document is not deleted by the admin through the platform or APIs, they will be available for 30 days after all signatories have signed the document. ### Can more than 1 person sign at the same time? While the invitation to sign can be sent to more than 1 person, only one person can sign at a given time. There will be an error message that pops up to try again later if a signing session is ongoing. ### Is bulk signing possible? This is not supported at the Sign with Singpass protocol does not allow signing on multiple documents or place multiple signatures at a time yet. If this is made possible in future, we will also consider! --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://guide.signify.gov.sg/frequently-asked-questions/faq/signer.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
