Pantry's RFID-enabled Food Kiosks Use Keonn UHF Antennas

Keonn Technologies has announced that Pantry, a U.S. fresh foodservice provider, is using 500 of Keonn's Advantenna-p13 reader antennas to track inventory and sales of food from its kiosks. In July 2014, the company began selling its smart sensor-based refrigerated kiosk, known as a Pantry, which features a built-in RFID reader to track the items stored inside the unit via tags affixed to food packaging (see PantryLabs' Vending Machine Dispenses Fresh Foods Via RFID). Pantry kiosks are now deployed across the country in workplaces, hospitals, universities and hotels to dispense fresh food and provide people with access to better food choices.

Customers can use Pantry's kiosks by simply swiping a card in the card reader. Keonn's antennas, incorporated inside the kiosks, track which items have been removed so that each item's cost can be calculated and the customer can be properly charged.

Pantry's RFID-enabled kiosk
Keonn's Advantenna-p13 is a compact ultrahigh-frequency (UHF) RFID antenna with circular polarization and a radiation pattern characterized by a 40-degree beam width in the endfire direction and a 90-degree beam width in the broadside direction. According to Keonn, this radiation pattern makes this antenna suitable for many RFID applications, such as loss-prevention systems, portals, tunnels, corridors and doors.

The antenna offers a 6.8 dBi gain and operates in the 865 to 868 MHz and 902 to 928 MHz bands, with an operating detection distance of up to 4 meters (13.1 feet). It weighs 350 grams (12.3 ounces) and measures 417 millimeters by 137 millimeters by 3.3 millimeters (16.4 inches by 5.4 inches by 0.1 inch), excluding the connector.
