Hi 👋 🥰 semi-new craft-fair-er

Ive been doing a few here and there with a friend of mine and she uses a pos on her phone to accept cards and will be moving away super soon so I want to get one and was hoping to get some recs for good ones that aren't going to screw me over 🥺 at the end of October ill be doing one all by myself for the first time and im nervous 😅 mainly looking for pos recs but any and all advice and tips is welcomed 💜💜 TIA
