Common Error Messages
This section covers common errors related to processing transactions with the iDynamo in ShopKeep. Visit our Credit Card Readers Troubleshooting homepage for errors not listed here.
"No Payment Processor Found"
This means the account is not set up for credit card processing.
- Contact your Point of Sale Specialist to sign up for ShopKeep Payments.
- Have an existing credit card provider? Ask them to fill out our boarding form.
- If you received an email stating the account was boarded, close the shift and open a new one.
"Couldn’t connect to processor" or "Can’t reach payment processor"
These two errors occur as the result of the iPad having poor or no internet connectivity.
- Press the iPad’s home button to exit ShopKeep.
- Open the Safari web browser and perform a Google search.
If results load, force quit and re-open ShopKeep, then run the credit transaction again.
If search results do not load, follow these additional steps:
- Open Settings and tap Wi-Fi.
- Check if the iPad is connected to the correct network. If not, switch it to the right one, force quit ShopKeep, and try the sale again.
- If the problem persists, troubleshoot the router or contact your Internet service provider for help.
"Quoting reference 4: Migrating to core data version 67. P.S.- We have a backup of your database."
The “We couldn’t update this register, we are really sorry about this. If this problem persists please visit shopkeep.com/support. Quoting reference 4: Migrating to core data version 67. P.S.- We have a backup of your database.” error occurs because of a problem between ShopKeep and the iDynamo credit card reader.
- Update the ShopKeep register app to the latest version.
Visit this support article if you need help updating ShopKeep.
- Open ShopKeep and try signing in again.
- Disconnect the iDynamo by unplugging it from the iPad.
- Turn the iPad off.
- Turn the iPad back on and open ShopKeep.
- Re-attach the iDynamo, then try signing in again.
- If the issue persists, contact ShopKeep Customer Care for further assistance.
"Card declined" or "Decline"
“Card declined” and “Decline” both mean the attempted charge was refused by the customer’s bank.
- Tap 'Retry' to try charging the card again.
- If declined again, have the customer contact their bank or finish the sale with a different card / tender.
"Error communicating with processor"
This error is different from “Couldn’t connect to processor”. It most often indicates an issue with how the account is set up. Contact ShopKeep Customer Care for assistance.
This error appears if the iDynamo was not purchased from ShopKeep or is no longer functional.
- Make sure the reader was purchased directly from our hardware site.
- Contact ShopKeep Customer Care for further assistance.
This may appear if the iPad is running an old version of ShopKeep or if the swiper is no longer functional.
- Update ShopKeep and try the transaction again.
- If the problem persists, contact ShopKeep Customer Care.
"Not a Credit Card"
The “Not a Credit Card” message appears when an employee swipes something other than a credit card, like a gift card. It can also occur if a credit card’s magnetic strip is faulty or damaged.
- Swipe a valid credit card.
- If the swipe fails, try to manually enter the card information.
- If the card is a ShopKeep gift card, tender the sale as Gift Card and swipe again.
- If the problem persists, contact ShopKeep Customer Care for further assistance.
Issues Without Error Messages
If you experience unusual behavior that is not accompanied by an error message, continue reading below.
The iPad prompts me to swipe a card on a transaction, but nothing happens when I do.
This can happen if a card isn’t swiped properly or if the magnetic strip has excessive wear that prevents the iDynamo from reading it.
- Check that you’re swiping the card with its magnetic strip facing down and toward the iPad. Make sure the entire strip is being swiped through the iDynamo.
- Try using a different card or manually enter the card information to complete the sale.
The iPad prompts manual card entry and won’t allow me to swipe.
You are forced to manually key in card information when ShopKeep and your iPad think the iDynamo is disconnected.
Attempt these steps and check after each if the issue is resolved:
- Unplug the iDynamo, check that you have the correct adapter sleeve connected to the reader (if applicable), and reconnect the card reader to the iPad.
- Force quit and reopen the ShopKeep app.
- Restart your iPad and open ShopKeep.
This can also happen if your iDynamo is not encoded for use with ShopKeep. If the problem persists beyond these steps, make sure your iDynamo was purchased directly from ShopKeep before contacting Customer Care.
This section covers miscellaneous issues not suited for the categories above.
The iPad won’t recognize the card reader.
Verify that the iDynamo was purchased directly from us to make sure it’s encrypted properly.
If the swiper was purchased directly from ShopKeep, follow the steps below.
- Unplug the card reader from the iPad.
- Force quit the ShopKeep register app.
- Shut down the iPad by holding the Power button until the screen turns black.
- Plug the card reader back in while the iPad is off.
- Power the iPad back on.
- Relaunch the ShopKeep app.
- Swipe the card.
My iPad doesn’t charge properly when I plug my cable into the iDynamo.
This could be caused by a problem with your power adapter, power outlet, micro USB cable, or iDynamo.
Power Adapter / Outlet
- Check that the micro USB cable plugged into the iDynamo is connected to the white power adapter that came with your iPad. Other power adapters may not provide enough energy to charge the device.
- Try plugging the power adapter into a different wall outlet to test if the outlet itself could be the problem.
Micro USB Cable
- Connect a different micro USB cable that you know works. If it charges the iPad, then you know the original cable is broken.
- Alternatively, use your existing cable to charge a different device (like a cell phone). If you experience problems charging the second device, the cable is your problem.
- Leaving your cable plugged into the iPad while rotating your stand can cause stress on the cable and iDynamo. To help mitigate potential issues, unplug the cable before rotating your stand or only plug it in when the iPad needs to be charged.
- If the Power Adapter / Outlet and Micro USB Cable sections do not help: unplug the iDynamo and try to charge the iPad by plugging a 30-pin or Lightning cable directly into its charging port.
- If the iPad charges with its own cable, the problem could lie with your iDynamo. Contact Customer Care for further assistance.
- If the iPad still won’t charge, there may be an issue with its charging port. Contact Apple for more help.
I lost the adapter sleeves that came with the iDynamo.
Purchase replacement adapter sleeves directly from the ShopKeep hardware site. Make sure to select the correct set of adapters (iDynamo 4 or iDynamo 5).
