Setup Issues
This section deals with issues you may run into while setting up a Clover device for the first time.
I cannot swipe between pages on my Clover device’s home screen and the Settings app is missing.
This issue can occur when a Clover device is left idle overnight. Follow the steps below to fix the problem.
On the iPad, force quit the Retail POS (S-Series) app.
On the Clover device, open the Network Pay Display app.
If Network Pay Display is on a page you can’t access, tap the overview button to select the app.
I rebooted my Clover device after it was idle overnight and it won’t connect to the register.
If you encounter this problem, follow the steps above to troubleshooting and resolve the issue.
My device is not powering on.
If the screen does not turn on after plugging the power cable into an outlet, the device is most likely not receiving power. After each step below, check to see if the problem is resolved.
Unplug the power cable from the power adapter, then plug it back in.
Unplug the power cable from the Hub, then plug it back in.

Unplug the power cable from its power outlet, then plug it into a different power outlet.
Make sure to use a known working outlet.
If a cash drawer is connected to the Hub, make sure the correct cable is in use.
For APG cash drawers, the CD-101A cable is the only compatible cable. If a different cable is connected, the device will not power on. Purchase a new cable here, if necessary.
For the Clover cash drawer, you must use the cable that came with the drawer.
Make sure there are no cables plugged into the Hub's USB ports.
These ports are not designed to charge third-party devices, such as the iPad register. Instead, use the specific power adapter included with a device to charge it.
"You've entered the wrong password"
This error appears on the Clover device when you enter a Wi-Fi network’s password incorrectly.
Look to see if you are connecting to the right network.
If you selected the wrong network, tap ‘Cancel’ and pick the correct one.
Follow steps 16 - 22 here to get a pairing code and continue with setup.
If the problem persists, follow the steps here to update the Clover device certificate.
The Retail POS (S-Series) app keeps prompting me to install a certificate.
If the Retail POS (S-Series) app continuously asks you to install a certificate after following the steps in our setup guide or after updating to iOS 13, it means the Clover device certificate needs to be updated. Follow the steps below to learn how to resolve this issue.
On the Clover device, open the Network Pay Display app.
If the Clover device displays the ShopKeep ‘Welcome’ screen instead of the home screen shown below, follow the steps here to exit to the Network Pay Display app.
If necessary, follow steps 16 - 22 here to connect the Clover Mini to the register.
I get a spinning gear or an X after I enter the pairing code.
A checkmark is needed to be able to use your Clover device. If you see a spinning gear or an X on the Integrated Hardware screen, it means there is a connectivity issue.
These errors appear on the iPad when it loses its connection to the Clover device. Most often, this happens because the iPad has automatically connected itself to a different network.
Press the iPad’s Home button to exit the Retail POS (S-Series) app.
Reopen the Retail POS (S-Series) app and try the sale again.
If the problem persists, follow the steps below to continue troubleshooting the issue.
Unplug your router from power, wait about 10 seconds, and plug it back in.
Once the router is back online, check if the iPad is connected to the correct network.
Reboot your Clover device.
"Transaction failed: invalid card"
This error appears on the Clover device’s screen if a customer swipes something other than a credit or debit card, like a gift card. It can also occur if the card’s magnetic strip is damaged.
Tap 'OK' to dismiss the error.
Have the customer swipe a valid credit or debit card.
If the swipe fails again, manually enter the card information.
If the card is an Integrated Gift Card, tender the sale as Gift Card and slide the card through the reader.
"Card declined"
If a “Card declined” error appears in the Retail POS (S-Series) app, it means the charge was refused by the customer’s bank.
In the Retail POS (S-Series) app, tap 'Cancel' and tender the sale again.
If declined again, have the customer contact their bank or finish the sale to a different tender.
“Unable to add tip”
This error occurs when you try to adjust a tip for an offline credit payment, but internet connectivity has not been restored to the register. Tips can only be adjusted when there is an active internet connection and the batch the transaction is from is still open.
Read the error, then tap ‘No Tip’ to close the sale without a tip or ‘Back’ to try again.

If you tapped ‘Back’ in the previous step, continue troubleshooting below:
I have not received money from my credit card transactions.
Deposits occur within 24-48 business hours of batch closure and, by default, most accounts batch out automatically every night. If you have not seen a deposit in several days, try manually closing your batch.
Follow the steps here to exit the Network Pay Display app.
Open the 'Closeout' app, then select the current batch.
Close the cover on the paper and reprint the receipt.

My business logo on printed receipts looks different than my email receipt logo.
Logos printed on paper receipts look different than logos on email receipts due to the limitations of thermal printers. For best results, optimize your logo for printing, then upload that new version to update the logo used for paper receipts, email receipts, and invoices.
Follow these tips to optimize your logo for paper receipts.

My iPad register does not charge while using the Clover Mini.
