The invention relates to an implementation method of a visitor
system based on two-dimensional code recognition. The implementation method comprises the following steps: S1, invitation information issent to a visitor in a message mode; S2, the visitor obtains an
access control two-dimensional code according to the invitation information; and S3, whether the
access control two-dimensional code meets the
access control opening requirement or not is verified at the access control position, if yes,
verification succeeds, a door opening
signal is sent to the corresponding access control, and otherwise,
verification fails. Compared with the prior art,
verification from invitation to arriving at the site and passage in the office environment of the visitor are achieved through a two-dimensionalcode technology, in the case of the network, self-service registration and passage of the visitor are completed, the situations that an access
control card is lost and not returned in time are avoided, the
workload of a receptionist in the existing office environment is reduced while the enterprise safety is guaranteed, unattended reception in wisdom office is achieved, and the office efficiency is improved indirectly.
