Your KEEP refreshes over NFC: your phone's NFC antenna needs to sit right in front of the KEEP's antenna. If the two antennas aren't lined up, nothing happens — even with NFC turned on.
It works exactly like a contactless payment: hold the wrong corner of your phone to the card reader and the payment won't go through. Move your phone a few centimeters and it works.
Here are the steps to follow:
- Make sure NFC is enabled on your phone and that your phone is unlocked.
- Make sure to place the NFC antenna on the product.
- Place the phone flat and directly against the keychain, and keep it still for a few seconds during the update.
