Mobile Safety Alert: Keeping Cash or Cards in Phone Cover May Increase Overheating Risk

Mobile Safety Tips: Why You Should Avoid Keeping Cash or Cards in Phone Case,Experts warn that storing money or cards in mobile covers may contribute to overheating risks. Know the facts, precautions, and safety tips.

April 29:

In an era where smartphones have become an essential part of daily life, a common habit—keeping cash or ATM cards inside mobile phone covers—may pose potential safety and functional risks if not handled carefully.

Many users tend to store ₹200 or ₹500 notes, or even debit and credit cards, in their phone cases for convenience. While this may seem harmless, experts suggest that such practices could interfere with heat dissipation and affect device performance over time.

Why Storing Items in Phone Covers Can Be Risky

Smartphones generate heat during regular use, especially while charging or running multiple applications. This heat is designed to dissipate through the device’s body. However, placing items like paper currency or cards between the phone and its cover may restrict proper ventilation.

In certain conditions, restricted heat dissipation could contribute to overheating, which may impact battery health and, in rare cases, increase the risk of malfunction.

Impact on Debit and Credit Cards

Storing debit or credit cards in mobile covers can also affect the card’s magnetic strip. Prolonged exposure to heat or electromagnetic activity from the phone may degrade the strip over time, potentially causing the card to stop functioning.

Role of Chargers in Overheating

Using non-original or low-quality chargers can further increase the risk of overheating. Such chargers may put additional stress on the battery, raising internal temperatures. If combined with blocked ventilation due to stored items, the risk may increase.

Safety Tips for Smartphone Users

• Avoid storing cash or cards inside phone covers
• Use a separate wallet or cardholder
• Do not use the phone extensively while charging
• Prefer original or certified chargers
• Avoid thick or poorly ventilated phone cases
