Fax polling is a feature that allows one fax machine to send a request to another fax machine for a specific document. This process is also called fax on demand. A document can be scanned and left in the load tray, where it can be polled by another fax machine at the receiver's convenience. Both fax machines must have the polling feature to be able to complete the procedure. If there are multiple faxes, they can be stored digitally and a list can be set in the sending machine's memory to designate which fax numbers are allowed to poll a given document.
While the rise of internet-based documents has made e-mail a popular way to transmit documents, many companies utilize fax polling for sensitive documents. Fax polling aids in transmitting confidential information with its ability to distinguish which machines are able to receive its information, unlike e-mail or web sites which could potentially be accessed by the public. Another benefit of fax polling is that the machine that is receiving the fax initiates the transfer, which means that the receiving machine will be charged for the transaction, not the machine which is sending the document.
