Implicature utterance refers to those utterances that conveys intents without explicitly mentioning it. It often happens when the user is not familiar with the chatbot service. And it usually needs further reasoning to infer the user intent. For example:

[Example utterance 1] "just found my old card"
Reasoning path: "found old card" --> "want to use old card" --> "how to link card to account"
[Example utterance 2] "i am tired of manually refiling my card balance"
Reasoning path: "tired of manually refilling" --> "want it automatic" --> "how to set up automatic top up"
[Example utterance 3] "i want to use my card without divulging my information"
Reasoning path: "without divulging information" --> "need verification when use card" --> "how to verify my identity"

Based on these examples, could you generate 3 implicature utterances for intent "why card not working"?
