Setting up a Square Reader with C-Trax takes just a few steps.
1. Check the Battery of Your Square Reader
For an accurate battery reading, unplug your reader from any power source. Firmly press the button on the reader.
Green lights indicate that you’re charged and ready to go. If you see a single red light, charge up immediately.
Once your reader is on, you don’t need to worry about turning it off. It’ll automatically go into sleep mode after 2 hours of inactivity.
To wake it up from sleep mode, firmly press the button on the side of the reader once.
2. Charge Your Square Reader
Connect one end of the accompanying USB cable to your reader and the other end to a USB port like a cell phone charger, computer, or car charger.
It will take around 2 hours for a reader with a low battery to charge completely.
Note: You can also use the Dock for Square Reader to keep your reader charged and in place while you take payments.
3. Wirelessly Connect Your Square Reader
Start by ensuring your iPad’s Bluetooth is turned on.
Open the C-Trax Serv app and tap Navigation > Settings > Square > Manage Readers > “Connect a Reader."
Follow the on-screen prompts to pair your reader to C-Trax Serv.
Any necessary firmware updates will be automatically installed once the reader has been connected.
When connected and updated, the reader will be listed as Ready in-app.
The wireless connection can be lost if the reader and device are more than 10ft apart.
Note: If your reader was previously paired to a different device: Keep in mind, if you are reconnecting a reader that was previously paired to a different device, you may need to forget your reader from the device it was previously paired with, as the Square reader can only be paired with one device at a time.
