There are cell phone apps for that, though I don't use them once I got Samsung Pay, which I now use for that purpose. I'm not sure what is the technology Samsung Pay uses for loyalty and library cards, but it's been flawless, and I've had checkout people exclaim when some loyalty barcode scans that they've never had that work before. It's like it's beaming the number, too, especially when I reach towards the flat grocery checkout scanner built into the counter and the loyalty card scans immediately, before the phone even gets horizontal.
The problem is that Samsung Pay is only on high end Samsung Galaxy phones, the S6 through S9 variants [EDIT: and the Note 5, which is very similar to the S6 Edge+ but with stylus and a flat instead of curved screen]
