What do you mean by, "POS application"?
Are you creating a peripheral to connect to existing equipment? If so, your device needs to do whatever this equipment expects!
Google. Amazing what you can find....
www.beyondlogic.org/.../usb4.shtml
"Bulk transfers can be used for large bursty data. Such examples could include a print-job sent to a printer or an image generated from a scanner."
www.jungo.com/.../USB_data_transfer_types.html
"Bulk Transfer is typically used for devices that transfer large amounts of non-time sensitive data, and that can use any available bandwidth, such as printers and scanners. "
And this after searching 10 secs....
POS is most often a Point-of-sales terminal.
