It is likely that you are presenting the iphone far closer to the reader than is necessary; perhaps even touching it.
When an iphone is turned on and comes into close proximity of an RFID field, the apple wallet will open. In this case that RFID field is being generated by the reader.
When utilizing the Pure Mobile credential, you can keep your iphone a good distance away from the reader and still successfully send the credential.
Please note that when multiple Isonas devices are near each other you will want to ensure your iphone is closest to the device you would like to send the credential to.
