Using Mobile Credential on your Apple Device

  • The J-Card readers are sensitive to the position of your device. Hold the top of your iPhone near a reader to use your J-Card, or your Apple Watch near the reader.

Just tap your device against the reader to recognize your J-Card. For iPhone 6/6 Plus, you’ll need to double click the Home button, tap your default payment card and select your J-Card. Verify your identity with Touch ID then hold the top of your phone near the reader.
  • To display your J-Card, open Apple Wallet and select your J-Card from your saved cards.
  • Contact information for the J-Card Office is also available from the J-Card menu in the Apple Wallet.

Android Users

Setting up Mobile Credential on Android

  1. NFC needs to be available on your phone and active for J-Card Mobile. If you’re not sure if your phone has NFC and if it’s enabled, go to your Settings menu and look for NFC. It may be under Connected Devices> Connection Settings on some phones. (If you can’t find it, use the search option on the top right to double check.) Once you find it, toggle the setting to On.
  2. Next, open Google Pay and make sure it’s enabled as well. If you don’t have Google Pay on your phone, you can download it free in the Play Store. If the app prompts you to add a credit card, you can bypass that screen and return to the Google Pay home screen.
  3. From there, open the Play Store (again, if you installed Google Pay), search for the eAccounts app from Blackboard and install it.
  4. Open eAccounts, click through the start up prompts and tap Get Started.
  5. Find Johns Hopkins University and continue to the JHED login screen.

  7. Once you’ve successfully authenticated, you’ll see your J-Card accounts (J-Cash, Dining Dollars and dining plans) along with any related transaction history.
  8. Click your photo on the upper left corner to add your J-Card to the eAccounts app.

Using Mobile Credential on Android

  • You don’t need to unlock your phone, but the screen must be awake to use your J-Card. Tap the power button to wake the screen and hold the middle of the phone near the top of the reader.
  • To display your J-Card, open the eAccounts app and click your photo in the top left corner.
  • To add funds to your accounts in the eAccounts app, save a payment method in J-Card Online first.

Once you have added the card information in J-Card Online, that card will be available in the eAccounts app for future deposits. If you’ve already used eAccounts to access your mobile credential, you’ll need to sign out and back in to update the saved payment information.
