Step 1:Let's solve this step by step:
Step 2:: Understand the context
Smartwatch payment systems use near-field communication (NFC) technology to enable contactless payments. We need to evaluate the potential security risks associated with this method.
Step 3:: Analyze the security mechanisms
- Modern smartwatch payment systems use several security layers: - Tokenization (replacing actual card details with unique tokens) - Encryption - Transaction-specific authentication - Limited transmission range of NFC (typically 4 cm or less)
Step 4:: Evaluate the options
A. Two-factor authentication is helpful but not the primary security measure B. This option suggests potential signal interception risks C. Phone encryption is a good practice but not directly related to payment security D. Suggests no security risks exist
Step 5:: Determine the most accurate answer
The correct answer is B: Yes, there is a risk that the signal could be intercepted and altered. Reasoning: - NFC signals can potentially be intercepted by sophisticated attackers - While rare, signal interception and manipulation are theoretical security risks - Proximity-based attacks like "electronic pickpocketing" are possible, though difficult - The risk exists, even if modern security measures make it challenging
Final Answer
B - Yes, there is a risk that the signal could be intercepted and altered.
