Setup Issues
This section covers issues that may occur while connecting the Moby/5500 to the Retail POS (S-Series) app.
The Integrated Hardware 'Card Readers' screen does not list the Moby/5500.
This happens when the Moby/5500 is powered off, not located close enough to the register, Bluetooth is disabled on the Retail POS (S-Series) app for iOS, or steps were skipped during setup.
Check if the Moby/5500 is powered on.
When powered on, the indicator light will lit.
If powered off, press the side button until the indicator light turns on. If the reader does not turn on, follow these steps below to troubleshoot.
Tap 'Begin Pairing' within the 'Using a Moby/5500?' panel and continue with setup.

Connect to an internet network from the Settings app of the iOS device.
Tap 'Credit', then try processing the sale again.
"Gateway Error"
This error occurs on the Retail POS (S-Series) app for iOS as a result of the register having little to no internet connectivity.
Make sure your network follows all recommendations in our Best Practices guide.
If the problem persists, reboot the router or contact your internet service provider for help restoring the internet connection.
"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 or tender.
"Invalid Entry", "Invalid Card", "Field format error", or "Invalid account number"
For swiped credit cards, ‘Invalid Entry’ and ‘Invalid Card’ mean you did not swipe a valid credit card or there was something wrong with the card’s magnetic stripe. For manually entered credit cards, these errors indicate either the Credit Card #, Expiration Date, Billing ZIP, or CVV were entered incorrectly.
If the error occurs while swiping a card, make sure you swiped a valid credit card.
If the swipe fails, manually enter the card information or swipe a different card.
If the card is an Integrated Gift Card, tender the sale as ‘Gift Card’ and manually enter the gift card number or scan its barcode.
If the error occurs while manually entering a card, tap 'OK' and reenter the card information.
Most credit card numbers are at least 14 digits and begin with 2, 3, 4, 5, or 6.
For Discover, MasterCard, & Visa: CVV is the 3 digits on the back of the card next to its last 4 digits.
For American Express: CVV is 4 digits on the front of the card above the card number.
This section covers miscellaneous issues unrelated to the sections above.
