This enables wireless tags to be shared in a manner that allows copies of the tags to remain synchronised with each other. The system includes a remote server, configured to selectively provide tag data to the wireless devices to enable the wireless devices to emulate the one or more wireless tags using the selectively provided tag data. In use, the wireless tags are configured to first retrieve tag data from the remote server, and subsequently emulate one or more wireless tags according to the retrieved tag data. ## Claims ### Claim 1 A wireless access system, comprising: a plurality of wireless devices dynamically configurable to emulate as one or more wireless access tags; and a remote server configured to selectively provide tag data to the plurality of wireless devices to enable the plurality of wireless devices to emulate the one or more wireless access tags using the selectively provided tag data; wherein: the one or more wireless access tags are configured to retrieve tag data from the remote server and emulate the one or more wireless tags according to the retrieved tag data; and each of the plurality of wireless devices is configured to upload updated tag data to the remote server to enable synchronization of the updated tag data across the plurality of wireless devices. ### Claim 2 (depends on 1) The wireless access system according to claim 1, wherein the plurality of wireless devices are configured to: emulate the one or more wireless access tags multiple times; and retrieve the tag data prior to each emulation of the wireless access tag. ### Claim 3 (depends on 1) The wireless access system according to claim 1, wherein the tag data includes a tag identifier and one or more keys for use in authentication. ### Claim 4 (depends on 3) The wireless access system according to claim 3, wherein the tag data further includes tag configuration data. ### Claim 5 (depends on 1) The wireless access system according to claim 1, wherein: the plurality of wireless devices are configured to emulate the one or more wireless access tags for use with one or more receivers; and the plurality of wireless devices are configured to retrieve the tag data independently of the one or more receivers. ### Claim 6 (depends on 5) The wireless access system according to claim 5, wherein; the one or more receivers comprise a legacy receiver; and emulation functionality is provided using the plurality of wireless devices and the remote server. ### Claim 7 (depends on 1) The wireless access system according to claim 1, wherein; the plurality of wireless devices coexist with legacy wireless access tags; and the plurality of wireless devices and the legacy wireless access tags are indistinguishable in their interaction with the remote server. ### Claim 8 (depends on 1) The wireless access system according to claim 1, wherein the plurality of wireless devices include first and second devices including the same tag data to enable duplication of one of the one or more wireless access tags on different ones of the plurality of wireless devices. ### Claim 9 (depends on 8) The wireless access system according to claim 8, wherein a first wireless device, of the plurality of wireless devices, is configured to share tag data relating to one or more of the wireless access tags with a second wireless device of the plurality of wireless devices. ### Claim 10 (depends on 1) The wireless access system according to claim 1, wherein the updated tag data comprises tag data received from a receiver in response to authentication with the receiver. ### Claim 11 (depends on 1) The wireless access system according to claim 1, wherein the remote server is configured to selectively remove tag data from one or more of the plurality of wireless devices to provide time-limited access to the one or more of the plurality of wireless devices. ### Claim 12 (depends on 1) The wireless access system according to claim 1, wherein each wireless device of the plurality of wireless devices is configured to store tag data corresponding to a plurality of tags, wherein the tag data is selectable to emulate a respective one of the plurality of tags. ### Claim 13 (depends on 12) The wireless access system according to claim 12, wherein said each wireless device is configured to automatically select a set of tag data, of a plurality of sets of tag data, based on a location or a detected field of a receiver in proximity to said each wireless device. ### Claim 14 (depends on 1) The wireless access system according to claim 1, wherein each of the plurality of wireless devices is further configured to upload logging data relating to tag use. ### Claim 15 (depends on 14) The wireless access system according to claim 14, wherein each of the plurality of wireless devices is further configured to upload location data. ### Claim 16 (depends on 1) The wireless access system according to claim 1, wherein the remote server is configured to: remotely update tag data on one or more receivers;
