Mai's Experience with Card Exposure

Mai, a 28-year-old office worker in Hanoi, accidentally left her credit card on a busy coffee shop table for five minutes. She didn't notice it until she got back to her office.

Panic set in when she realized she couldn't find the card. She immediately opened her banking app, feeling completely overwhelmed by the potential for theft.

She hit the 'Freeze Card' button, which gave her the breathing room to call her bank calmly. It turned out no unauthorized charges had been made yet.

The bank blocked the old card and sent a new one within three days. Mai now keeps her card tucked away in a zipper pocket, turning a stressful lesson into a permanent habit.
