What is Reddit's opinion of ResSaldo?

From 3.5 billion Reddit comments

ResSaldo! Har du en kompatibel Androidlur kan du kolla saldot på ditt lokaltrafikskort (ex. Sl-kort, Jojo-kort) via telefonens NFC-läsare. Otroligt smidigt.

I use it mainly together with Android Beam and a nifty little app called ResSaldo, that allows me to se the balance on my top-up travel fare cards (MIFARE) here in Sweden.

Skanna med mobilen och ReSaldo appen? https://play.google.com/store/apps/details?id=se.supertips.android.ressaldo
