QuickMark Spot is a free Mac utility that works in conjunction with QuickMark QR Code Reader for iPhone.
QuickMark Spot enables a Mac computer that is in the same local Wifi network as your iPhone to receive scanned data from QuickMark for iPhone.
When connected, the barcode data scanned by QuickMark for iPhone will be automatically "pasted" to where the cursor lies on the Mac.
One may find it useful as simple and straight forward data collecting tool.
For example, one can turn on QuickMark Spot and then open a new TextEdit or Excel file on their Mac and start compiling a list of product serial numbers by scanning barcodes with QuickMark on his/her iPhone.
