Contactless 125KHz RFID Proximity Smart Cards, Read Only, Pack of 50 Overview These contactless 125KHz RFID proximity smart cards are designed for reliable identification in mediumrange reader setups. Each card is read only, 0.9mm thick, and supplied in a pack of 50 for easy deployment across small to large systems. Key benefits Reliable identification: Consistent read performance with compatible 125KHz proximity readers for daytoday access control and ID verification. Stable readonly format: Read only operation keeps card IDs fixed for predictable, tamperresistant identification. Ready for bulk deployment: Pack of 50 simplifies provisioning for offices, facilities, events, or membership programs. Durable, thin construction: 0.9mm thickness gives a robust card feel while fitting standard card holders and access systems. Simple compatibility: Works with systems and readers that accept 125KHz proximity, readonly cards, enabling straightforward integration. What these cards do Frequency: 125KHz contactless RFID for proximity reading. Function: Read only smart card for stable, fixed ID credentials. Thickness: 0.9mm, designed to work with standard card slots, holders, and readers. Quantity: Pack of 50 for consistent, largescale use. Performance notes Midrange reading: Optimized for medium read distances typical of proximity access systems; actual range depends on reader model, antenna, and installation environment. Handling: Store flat and avoid excessive bending to preserve card integrity and read reliability. Practical use scenarios 1) Office access control: Issue these cards to staff for secure door access and identity verification with 125KHz proximity readers. 2) Time and attendance: Use readonly cards for reliable clockin and clockout identification across multiple departments. 3) Events and membership: Distribute as event passes or membership cards where fixed ID credentials are required and quick scanning is needed. What to check before ordering Confirm your reader frequency and readonly support match 125KHz proximity cards. Verify reader placement and antenna setup for midrange reading performance. These cards provide a straightforward, durable, and consistent solution for bulk identification needs where 125KHz proximity, readonly credentials are required.
