Detailed Product Description
Secure your premises and professionalize your identification system with the EM4100 125kHz Printable RFID Card. This is a thin ISO proximity card made from high-quality PVC, designed to work seamlessly with standard 125kHz RFID readers commonly used in Bangladesh for office attendance and apartment security.
Unlike thick “clamshell” cards, these cards feature a smooth, flat blank white surface on both sides. This makes them printable, allowing you to use thermal transfer ID card printers to print employee photos, names, logos, and barcodes directly onto the card.
How it Works:
Each card comes pre-programmed with a unique 64-bit ID number that cannot be changed. You simply scan the card into your system (Access Control or Time Attendance machine) to register the user.
