Check the basics
Your seller profile is approved. You can't sell before it is.
Your Jim app and your phone are updated to the latest version.
Your phone has NFC and isn't jailbroken or rooted. Jim doesn't work on tablets or computers. See Is my device compatible with Jim?
You're in one of the 50 U.S. states. Tap to Pay doesn't work outside them, including U.S. territories.
Check your phone settings
Turn on NFC.
Turn on Location.
Grant the permissions Jim asks for. Tap Continue, or Go to settings if you denied them before.
Turn off developer mode.
Close split screen and any apps that show over your screen.
Set your date and time to automatic.
Then tap Try again.
Find the NFC spot on your phone
On Android, Jim can help you find where the NFC antenna is on your phone. When the app shows the tutorial, tap Find it now and hold the card against the back of your phone until it works. Use that same spot for every tap.
Your first charge
The first time you charge, Jim may take up to 1 minute to set up Tap to Pay. Don't close the app.
Check your connection
Use stable Wi-Fi or a strong cellular signal.
If you're on mobile data, make sure Jim is allowed to use it in your phone settings.
Try switching between Wi-Fi and mobile data.
Check the customer's card
Jim accepts credit and debit cards from Visa, Mastercard, American Express, Discover, JCB and Diners Club, and digital wallets like Apple Pay, Google Pay and Samsung Pay.
If the app says the card issuer blocked the sale, ask your customer to try another card or contact their bank.
If the app shows Transaction denied with "This transaction was denied", the sale was stopped by Jim's security review. Start with sales of your usual amounts, and don't retry the same sale many times in a short period. If it keeps happening, contact us.
If your account needs anything from you, we'll always let you know.
If your sales are paused, see What is my sales limit with Jim?
Still can't use Tap to Pay?
You can still get paid with a Payment Link or your Jim Website. See How can I sell using Jim?
If you don't see an option, update the app.
