There are several reasons why your card might not be detectable:
- Not positioning the card against your phone correctly: Phones will usually, but not always, have the detection area located in the upper part of the phone. While maintaining contact between your phone and OPUS card, slide it down your phone. It will vibrate once you hit the detection area.
- Not holding your OPUS card against your phone for long enough: The OPUS card must be kept flat against the phone for a few seconds for the reader to work properly.
- Not being able to read the OPUS card chip: Some cards use older chips that cannot be read or recognized by the NFC feature.
- Protective case or shell interfering with the NFC signal: Please remove your phone from its case or shell and try again.
If you are still having difficulties reading your card’s contents, please let us know by using “Contact us” in the app or by sending us an email indicating the issue at support_chrono@artm.quebec.
