I am a Hong Kong user, the common NFC application under the transportation in Hong Kong is, namely Octopus. the detection of the card is very annoying that is about 30 times per each even it cannot detect. Could you tell me, it is a device problem or an apps capability problem?
here is the Octopus reference link" https://www.octopus.com.hk/en/consumer/index.html" I will then ask them, the Octopus company also.
