Basic Hardware Troubleshooting for Card Readers

January 23, 2026January 23, 2026

Most card reader issues can be resolved by doing some basic troubleshooting. Use the section below to complete steps before moving on to more advanced troubleshooting.

 

 

Power Off and On Again

Sometimes turning a device off and on again can clear the device cache, install pending system updates, and do other troubleshooting. This should always be the first step. 

P5 Credit Card Reader

When you first receive the device, it should come partially charged. Use the USB-C wall charger to begin charging the device to full power.

  1. Once charged for at least 30 minutes, hold down the power button on the right hand side until the screen turns on.

  2. Once the device is powered on, pressing the power button once will sleep/wake the device.

  3. To fully power off the device, hold down the power button until the Power Off option is shown on the screen.

  4. Tap it.

If you need to replace the battery, lift up from the indentation at the bottom-center of the back cover to detach it from the device.

Please Note: Ideally, the terminal should be powered off each evening and powered on each morning to receive automatic software updates.

If the payment terminal is turned on for the first time, or after it was off for a long time, it may need to check for updates, which can take 10 to 20 minutes.

While the terminal is updating, the screen may flash or appear to turn off. Once the update is done, the screen should turn on.

When you first receive the device, it should come partially powered up. Use the supplied wall charger to begin charging the device to full power.

Turn on the Terminal

  1. Once charged for at least 30 minutes, press and hold the power button until the display turns on.

  2. If necessary, connect the terminal to a power supply to charge the battery.

  3. Once the device is powered on, press the power button once to sleep or wake the device.

Turn off the Terminal

  1. Press and hold the power button until a dialog box appears.

  2. Confirm you want to turn off the terminal.

Please Note: You should power off the terminal every evening and power it on every morning to receive automatic software updates.

When you first receive the device, install the battery. With the back of the device facing you, lift up from the indentation at the bottom left corner to detach the back cover. Insert the battery by sliding it into the exposed slot with the gold connectors at the top aligned. Once the battery is in place, charge the reader. Connect the reader to power by plugging the provided cable into the port with the lightning bolt symbol.

Please Note: The card reader, battery pack, and USB charger should all be included in your box, however, a USB wall outlet is NOT included. You may charge the readers using a USB outlet on your computer or purchase a USB wall charger at most electronics / office stores.

Once charged, hold down the power button on the right hand side until the screen turns on. Once the device is powered on, pressing the power button once will sleep and wake the device. To fully power off the device hold down the power button until the power off option is shown on the screen, then select it.

Please Note: Even when it’s not in use, leave the BBPOS WisePOS E / S700 plugged in and powered on to receive automatic software updates.

 

Check the Terminal is Paired

Sometimes transactions started from the point-of-sale may not reach the terminal. The most likely reason for this is that the device was not paired correctly or lost connection with the internet or point-of-sale. To check for this, review the following page:

Check the Splash Screen

If this is the first time the terminal has been paired, it should show the default splash screen, which is a blue patterned background.

If the terminal has been paired before, it should show an screen that reads Bottle POS.

 

Turn Wi-Fi Off/On Again

Sometimes the terminal can lose connection to the network or have a poor connection. While these notifications should display on the device, it is possible to miss them. Turning the Wi-Fi off/on again will prompt a message if it can’t connect or doesn’t have a strong connection. If one of these messages pops up, reference the network troubleshooting steps.

The terminal must be connected to the internet before it can be paired or updated. For best performance, it should be connected to the same network as the point-of-sale computer.

  1. Once the device is powered on, unlock the device by using your finger to swipe from the bottom of the screen to the top of the screen.
  2. Once on the Home screen, repeat this process by swiping up again to show the device applications.
  3. Tap on the Settings app and go to Network & Internet.
  4. Select the Wi-Fi network and enter your network details.

Please Note: The Wi-Fi network must use WPA-Personal or WPA2-Personal encryption and be password protected. WiFi is not supported for non-password-protected networks or enterprise networks.
