Operating over radio waves, it allows for tap-and-go interaction without physical contact, typically over a distance of a few centimeters. These are standard in 2026 for secure data sharing and access control, fitting conveniently in any standard wallet or purse.
An RFID blocking sleeve is a lightweight solution designed to prevent unauthorized scanning or cloning. These specialized materials create a Faraday cage effect, effectively isolating your ArmerTech hardware from external cloning devices.
