What is the difference in the actual reader hardware itself ?
That is, what brand of terminal does walgreens use vs. safeway ?
In this late year of 2017 I know that many new NAS devices use cheap processors that make it difficult for them to run rsync over ssh ... it's too computationally expensive to encrypt the data stream at a high network speed.
If NAS vendors make that decision I wouldn't be surprised if some payment terminal vendors make similar decisions ...
