Hacking a Symbol Barcode Scanner at Kohls
Monday, September 05, 2005
From the main screen which tells you to scan an item to verify its price, I tried a sequence of buttons in rapid succession but didn't come up with much. I finally tried holding random buttons down for a few seconds and lo and behold a different screen popped up. Holding down buttons 1,3 and 4 for about 2 seconds, I was greeted with a very familiar blank screen with a crosshair asking me to recalibrate with a stylus (hrmm, Palm OS??). Well luckily for them, I left my Palm Tungsten (haven't used it for ages now) at home so I wasn't able to do anything at this point. I decided to try and see if I could find any other key commands.
From the recalibration screen, I held down buttons 3 and 4 and was sent back to the main page asking me to scan an item BUT this time I was rewarded with a QWERTY keyboard onscreen labeled 'input panel.' Cursing the gods for not having a stylus, I was dragged away to look at womens' clothes (not by choice mind you).
I was able to spend a few seconds and minutes on the other Symbol kiosks at the store (about 5) and found that 4 of them would immediately send me to the stylus recalibration screen when holding down the 1,3 and 4 buttons but one kiosk refused to do so. I was also not able to duplicate the main screen + QWERTY except on one kiosk. Looks like I will have to make another trip out there with a stylus very soon. If anyone has information on this, I would love to hear it.
