I don't know is the right place or not to ask this question. I have a web-based inventory application that is running on Ipad. For that application, my client wants to add a point of sale capabilities.

  1. Connect to a wifi printer to print invoices.
  2. Add a barcode reader to add items to the invoice list.
  3. Connect to a card swap device to get the card payments from the customer.

I think the first one can be done. I have done that before. Others I am not sure about. Can we connect to a wifi barcode reader to Ipad and then access that device via chrome or safari browser inside our web app?

and also can we connect a card swap device for payments?

If these two are possible what are the recommended devices for the job?
