Share 'UV/ IR QR Code Pen Scanner'
Hi, Does anybody know if there is a PEN scanner (i.e scanner wand) that can scan QR code that are printed using UV or IR inks, i.e. pen scanner to detect invisible QR code? In terms of invisibility, can anyone advise of the advantages and disadvantages of using IR vs UV inks? Best regards, soom
