PayPal has recognized that their Here credit card swipe reader doesn't work on the S4.
Previously the swipe just didn't work. Now the app says it's incompatible with the device.
They emailed me that they are working on an update for the app. (Earlier they had sent me a Here device with white insulators on the plug, which was supposed to be S4 compatible, but it was worse than the original Here.)
The S4 is still not on their list of incompatible devices (linked from the app error message), so either they expect a quick fix or they haven't yet fixed the list.
The Bank of America Mobile Pay app and reader work fine with my Verizon S4.
