Managing Emergency Contact Numbers Safely
When fraud strikes, the most critical action is calling your card company immediately. But finding the right emergency number in a panic can be difficult.
Store all your card emergency numbers in a LOCK.PUB encrypted memo with password protection. It's secure, accessible when you need it, and can be shared safely with family members.
Spotting Phishing Scams
| Legitimate | Fraudulent |
|---|---|
| Official domain | Similar domain (e.g., amazom.co.jp) |
| Never asks for card details | Requests card number and PIN |
| Valid HTTPS certificate | Certificate errors or warnings |
Summary
| Situation | Action |
|---|---|
| Unrecognized charge found | Call card company immediately |
| Phishing email received | Delete without clicking links |
| Card lost | Call card company to suspend |
| Online fraud detected | Report within 60 days |
Credit card fraud can happen to anyone. Make transaction alerts and regular statement checks a habit. Store emergency numbers securely with LOCK.PUB.
