Provided is a visitor identification system, including: a wireless transmitter; a visitor application; and a management server; wherein the wireless transmitter is installed by a resident and transmits a near field wireless signal; wherein the visitor application receives the near field wireless signal from the wireless transmitter, extracts a first identifier from the wireless transmitter, and transmits the first identifier to the management server, wherein the first identifier is unique to the wireless transmitter; wherein the management server receives the first identifier from the visitor application and performs one or more predetermined tasks so that a resident can verify identity of a visitor.

Visitor identification system

A print medium for ink-jet printing comprises a base substrate, a micro-porous ink-receiving layer, and a backing layer. The base substrate can include raw base paper and a moisture barrier layer between the raw base paper and ink receiving layer. The ink-receiving layer can be a micro-porous type, and can be applied onto the moisture barrier at the first side of the base substrate and the backing layer can be applied to a second side of the base substrate. The backing layer can include an extruded coated polymer layer and can be configured to transport solvent vapor to the base substrate at the rate of at least 15 g/m/24 hr.

Stackable ink-jet media

The present invention is drawn to a coated substrate for ink-jet ink printing. The substrate can have an ink-receiving coating on the imaging side. On the opposite, or back, surface, the substrate can have two coatings: a curl control coating and a photo feel coating designed to provide scratch resistance. The curl control coating can be nearest the substrate, with the photo feel coating coated over the curl control coating. The photo feel coating can have a contact angle greater than about 90 degrees and a water vapor transport rate of greater than about 5 g/m/12 hour.

Coated media for improved output stacking performance

An image recording medium has a substrate having a hot melt extruded ink-receiving layer formed on a first side of the substrate. The ink-receiving layer includes at least 50% of a hydrogel by weight. The hydrogel is capable of absorbing at least 50% of its dry weight of water.
