Hi @Paulsbread, thank you for reaching out! There are a few ways you can have your wife and son set up on your Square account so they can take payments on your behalf.
1. You can be logged into the same Square account on multiple devices simultaneously so they can download the Square app onto their phone and login using your email & password.
2. If you don't want to share you login information, you can create a device code and have them login that way.
3. You can also set them up as Team Member on your account and let them login using their own email and password.
The reader only connects to one device at a time, so if you'd like to take payments on three different devices simultaneously, you'd need another two readers.
I hope this help! If you have any question let me know.
