 Please be aware that using barcode scanning is not to be entered into lightly and is not the problem-free solver of all supply chain problems that some people think it is. It can have large implications for your organisation, in terms of changing processes and increasing workload in other areas.
-Currently, very few barcodes on pharmaceutical products contain batch and expiry information.   Our own checking (2018) shows it's only around 10% in typical warehouses.  So, for barcodes to be really useful, you will probably need to print and stick new labels on most stock as it comes into your warehouse. And you'll need to do it again if you have just barcode labelled the outer carton, and you also want to label each of the inner packs... These two alone can easily outweigh any benefits of using barcode scanners...

 ==== The barcode scanner ====
 A single barcode scanner can be attached to each computer running mSupply. The barcode scanner must:
-  * be able to read both the 1D 128 bit barcodes and 2D datamatrix barcodes used by the GS1 standard
+  * be able to read both the 1D 128 bit barcodes and 2D datamatrix barcodes used by the GS1 standard.
-  * communicate with the computer through a serial port. Note that this does not mean that it must connect to the computer via a serial port (these disappeared from computers many, many years ago!). The best way of achieving this is to buy a scanner that connects by USB and has serial port emulation software provided by the manufacturer
