Mobile business hardware

[QE]

Can someone with experience in a mobile business recommend any hardware that fits my needs as follows:

I'm starting a business that is basically selling products out of my backpack.

I can't drive so everything has to be light.

I have read a few posts on choosing the right hardware but it's still unclear.

I have the stripe reader.

I'd like a POS that is separate from my phone as well as the ability to scan barcodes/QR codes and print a receipt.

It can use my cellphone data hotspot if  needed.

The square terminal is what I would recommend based on your post.  It can't scan barcodes though, but has a built-in screen and chip reader, an old magstripe reader, and printer, and is powered by a built-in battery.  you would need to tether it to your phone or wifi for internet connectivity though.

Have you used it?

It seems like a good option but how does it do in everyday use?
