Home Hacks: Aluminum Foil Shields NFC Cards, Vinegar Mix Blocks Ants

A simple method to protect contactless credit and debit cards involves completely wrapping the card in aluminum foil, which blocks the NFC signal that thieves use for wireless skimming. Users are advised to ensure full coverage and may also disable the contactless feature with their bank for added security.

Another home remedy creates a lasting ant barrier by mixing equal parts white vinegar and water with 15‑20 drops of essential oil such as mint, tea tree, or citrus. The spray destroys ant pheromone trails and repels the insects when applied to door frames and thresholds, requiring weekly re‑application to stay effective.
