Coin Cards (Sticker Type)

RFID Coin Cards (Sticker Type) provide a creative and highly practical alternative to traditional cards and key fobs. These small, circular “discs” are embedded with an RFID chip and antenna, then encased in a durable, waterproof PVC shell. The back is fitted with an industrial-grade 3M adhesive, allowing the user to stick the tag onto the back of their mobile phone, a laptop, or even a specialized piece of equipment. This makes them ideal for users who prefer not to carry extra items on their keychain but want the speed of contactless entry.Key FeaturesPowerful 3M Adhesive: Features a high-bond adhesive that sticks securely to plastic, metal, and glass surfaces, ensuring the tag stays in place through daily use.Ultra-Slim Profile: At only 1mm–1.5mm thick, these stickers add virtually no bulk, making them perfect for sticking to the back of a smartphone or inside a phone case.Waterproof & Durable: The sealed PVC housing protects the internal chip from moisture, dust, and physical impact, making it suitable for both indoor and outdoor environments.Multiple Frequency Options: Available in 125kHz (EM) for standard proximity systems or 13.56MHz (Mifare) for high-security encrypted applications.Anti-Metal Option Available: Specialized versions include a ferrite layer that allows the sticker to work even when placed directly on a metal surface (such as a phone’s internal battery cover).Technical SpecificationsFeatureSpecificationAvailable Frequencies125kHz (EM) or 13.56MHz (Mifare)Diameter25mm / 30mm (Standard sizes)Thickness1mm – 1.5mmMaterialWaterproof PVC / EpoxyAdhesive Type3M High-Strength AdhesiveReading Distance1cm – 5cm (Depending on the reader)Operating Temp-20°C to 60°CUnboxing: What’s in the Box?RFID Coin Card Stickers (Available in packs of 10, 50, or 100)Note: Stickers are provided on easy-peel sheets for quick deployment.The BenefitsMaximum Convenience: Most users never leave home without their phone; by sticking a coin tag to the device, they ensure they always have their building access credential with them.Discreet Security: Because of their small size, these tags can be placed inconspicuously, reducing the risk of them being noticed or targeted for cloning.Versatile Asset Tracking: Beyond door access, these stickers are excellent for tagging assets, equipment, or tools for inventory management and check-in/check-out systems.Who Uses It?RFID Coin Card Stickers are the preferred choice for:Tech-Savvy Professionals: Who want to integrate their office access with their smartphone or laptop.Gym and Spa Members: Who prefer a small, waterproof tag that can be stuck to a water bottle or locker key.Logistics and IT Departments: Using the stickers to track high-value equipment like tablets and portable scanners.Shared Workspace Users: Providing a small, easy-to-carry alternative to traditional office badges.
