%0 Journal Article %T From Barcode to QR Code Applications %A L¨¢szl¨® V¨¢rallyai %J Agr¨¢rinformatika Foly¨®irat %D 2012 %I Hungarian Association of Agricultural Informatics %X This paper shows the Zsoh¨¢r Horticulture Company in Nagyr¨¢kos, how they want to change their barcode identification system to QR code. They cultivate herbaceous, perpetual decorational plants, rock-garden, flower-bed and swamp perpetuals, decorational grasses and spices. A part of the perpetuals are evergreens, but most of them has special organs - such as onions, thick-, bulbous roots, "winter-proof" buds - so they can survive winter. In the first part of the paper I introduce the different barcode standards, how can it be printed and how can it be read. In the second part of the paper I give details about the quick response code (QR code) and the two-dimensional (2D) barcode. Third part of this paper illustrates the QR code usability in agriculture focused on the gardening. %K barcode %K QR code %K gardening %K smartphone %K Zsoh¨¢r Horticulture %U http://journal.magisz.org/index.php/jai/article/view/92/57
