Payment App Chargebacks

[Graciela Garcia]

I dont currently use a payment app to collect rents, but I am trying to learn more about them.  I only have 3 rentals at the moment.  I read on BP about several recommendations that sounded great.  Someone mentioned the term "PCI Compliant" (or something like that) and something about renters possibly able to do chargebacks before moving out.  One writer mentioned that PCI Compliance is needed to avoid this.  ????   Are these chargebacks possible, and if so how to avoid?  What apps would prevent this from occurring?  I am a "small timer" which also happens to be "tech challenged", so an uncomplicated app would work best for me.  Info and suggestions would really be appreciated.  Thank you in advance.
