Utilizing the cable components outlined above, the Billfold Operations department recommends the following electrical component set-up for devices to optimize performance and battery life depending of the device utilization.

Standard power and cable setup for devices connected directly to a power source.

Wiring set up includes: a right angle adapter, a USB-C Splitter, USB-A Splitter, USB-A to USB-B Cable (for the RFID reader) and an Up Angle USB-C to USB-A cable (for the Credit Card reader) with data blocker

This schema has the right angle adapter plugged into the tablet’s USB-C port, the USB-C splitter is then connected to the adapter with the USB-A splitter plugged into the female USB-A port on the connected splitter. This allows the USB-A to USB-B cable for the RFID reader and the USB-A to USB-C cable for the Credit Card reader to receive power from the tablet and allows the RFID reader to communicate necessary data. The credit card reader cable will have a data blocker added to its USB-A side prior to connecting to the splitter to prevent unnecessary data communication attempts. The remaining female USB-C port will be used for a standard charging cable and power source to provide consistent charge to the device.

Standard power and cable setup for devices on battery packs.

Wiring set up includes: a right angle adapter, a USB-C to USB-C power cable, a USB-C Splitter, an Up Angle USB-C to USB-A cable (for the Credit Card reader), USB-A to USB-B Cable (for the RFID reader) and a battery pack (minimum recommendation is 20kmAh capacity)

This schema has the right angle adapter plugged into the tablet’s USB-C port and the USB-C splitter connected to the adapter. The USB-C to USB-C power cable is then connected to the USB-C female power port and the battery pack to maintain the tablet’s charge and the USB-A to USB-B RFID cable is plugged into the female USB-A port of the splitter to allow power and data communication. The USB-C to USB-A cable is plugged directly into the battery pack to maintain the card reader’s charge.

Utilized primarily for devices operating the POS application with only credit card payments enabled.

This schema has the right angle adapter plugged into the tablet’s USB-C port, the USB-C splitter is then plugged into the adapter which allows the USB-C to USB-A cable to plug into the tablet to maintain the credit card readers charge and a wall powered charger to be plugged into the female USB-C power port. The credit card reader cable will have a data blocker added to its USB-A side prior to connecting to the splitter to prevent unnecessary data communication attempts.

The device tablet can be turned on/off via the power button located on the bottom right of the hardware case. The power button is located on the tablet's base on the same side as the RFID Reader and is accessible via an open slot in the tablet casing.

Once powered on the tablet should show the Billfold logo with at least 2 applications on the home screen.
​If there are no applications, or the incorrect applications for event operations on the home screen, please notify the Billfold team.

Device tablets have about 5 hours of internal battery life at a full charge, but should always be plugged in during show hours using the USB-C charging cable.
If power outlets are not available, battery packs can be used.

The device battery life can be found in the top right corner of the tablet screen after swiping to reveal the navigation buttons

From the device home screen, swipe from any of the screen borders to bring up the tablet navigation buttons then swipe down from the top of the screen to open the device notification center.
The settings icon is in the top right corner.

Open settings and select "Connections" from the settings menu. Tap "Wi-Fi" within connection settings to enter network discovery mode and network settings.

Select the desired SSID from the list of available networks, input the password if applicable, and tap "Connect."

Open settings and select "Connections" from the settings menu. Tap "Wi-Fi" within connection settings to enter network discovery mode and network settings. Scroll to the bottom of available networks and tap "Add Network" to input private network SSID information. NOTE: When inputting SSID it is important to type the network name exactly, matching any character cases or spaces within the network name.

If the private network has a password or additional security configuration, tap "Security" below the network name to select the appropriate security settings. Most networks utilized "WPA/WPA-2 Personal" security configuration however you should confirm with your network administrator to confirm otherwise.

Once the network name and password have been input, select "Save" at the bottom of connection settings to add the network to the device.

Devices that are operating as a Dual Screen POS (DS) need to be paired to one another via bluetooth connection in the device settings in order for the POS operating applications to interface. See steps below for how to bluetooth pair the devices.

The range for bluetooth connection between the devices is minimal (<5ft) the devices base tablets are codependent lovers. Try to keep them close, and they’ll be happy.

Step 1.
Go to the ”About Tablet” section of the device. Verify/change the name of the devices.

​

Step 2.
Open up “Connections” section of the tablet and tap “bluetooth” to the left of the toggle

Step 3.
Select the appropriate device from the discovery list.

The devices will prompt bluetooth pairing request. Tap “OK/Pair” on both devices

Step 4.
Verify successful pairing connection

The following guidelines apply to android OS that have been found to optimize the user experience with Billfold Applications. They apply to all Billfold devices.

All devices come default with these settings however should they be changed for any reason please use this as a reference.

Overheating: Devices can overheat if kept in direct sunlight for too long and should be kept in the shade whenever possible.

If the device does overheat, the notification shown below will appear. Move the device to a shaded area to cool down before resuming operations.

Water Damage: Devices are water resistant, not water proof. In the case of inclement weather, devices should be covered and kept out of any direct water downfall.

The device will prompt a notification that water has been detected if any internal components are at risk. Move the device to a dry place and monitor. If the device has been water logged (deemed inoperable due to water damage) contact the Billfold team to discuss exchange and service options.

Screen Sensitivity: It is advised to wipe down the device screen after all operations. If the device screen is in the way of drinks and alcohol, residue on the screen will affect touch sensitivity performance

Device Reboot: If the device is suddenly not operating as expected a device reboot is advised by holding the power button and tapping the “reset” prompt on the screen two times.

Tap the reset button and then tap again to confirm device reboot

Reader Reboot (Power Surge Reset): If a payment accessory is not operating as expected, for example the RFID scanner is beeping but not giving any scanning output, reset the data and power connection to these components to reboot them
