Tiny Sticker, Big Shield: A Low-Cost Defense Against Card Skimming
Experts say a small opaque sticker on a card can obscure data like CVV, name, and expiry from skimmers and bystanders, while leaving the chip, magstripe and NFC functional. It’s inexpensive, easy to apply, and works best as part of layered security (monitoring, shielding PINs, mindful wallet use). Choose a durable, residue-free cover that fits the card’s data without touching the chip, and replace as needed.
