Is it possible to run 3 barcode scanners into the one PC if so how do I do it?

Bar-code scanner ussually act as keyboard. The go between the key-board and the PC. If you want 3 scanners, you can put them after eachother

PC - BAR1 - BAR2 - BAR3 - KEYBOARD

But you can't figure what scanners the input comes from

unless they are USB (in which you CAN)
or SERIAL (in which you need a switching device)
or PARALLEL " " "
