OEM SD5SC6 Dual Frequency EM 125kHz Mifare 13.56MHz Card

OEM SD5SC6 Card

The OEM Dual Frequency Card integrates two distinct RFID technologies into a single ISO-compliant form factor. This hardware solution enables seamless migration between legacy low-frequency systems and modern high-frequency security infrastructures. It houses both a 125kHz proximity chip and a 13.56MHz contactless smart chip. Engineers often deploy these units in facilities transitioning to encrypted protocols without replacing existing hardware. The design allows one credential to interface with multiple reader types. This architecture eliminates the need for personnel to carry separate badges for different access points.

The internal EM chip operates on the 125kHz frequency band. It supports common proximity reader protocols for basic identification tasks. Simultaneously, the Mifare-compatible 13.56MHz chip follows ISO 14443A standards. This secondary chip provides data storage and security features for logical access or cashless vending. The thin profile maintains compatibility with standard card printers. High-quality PVC construction ensures durability during daily use. The surface accepts thermal transfer and dye-sublimation printing for photo identification. Each unit undergoes strict quality control to prevent chip interference between the frequencies.

Internal antennas are positioned to minimize crosstalk within the card body. This configuration ensures reliable read ranges for both proximity and smart card readers. IT professionals utilize these hybrid credentials to consolidate user badges. One badge manages physical gate entry, secure printing, and point-of-sale transactions. This consolidation reduces procurement costs and simplifies inventory management. The CR80 dimensions match standard credit cards exactly. Users find the lightweight design convenient for lanyard or wallet storage. Consequently, the organization benefits from a more efficient credential lifecycle.

Security managers appreciate the flexibility of dual-technology hardware. It bridges the gap between older 125kHz systems and high-security 13.56MHz environments. The card supports 1k byte or 4k byte memory options depending on specific chip selection. This capacity allows for multi-application storage on a single credential. The passive RFID design requires no internal battery. Power is harvested from the reader magnetic field during communication. Operating temperatures range from -20 to +50 degrees Celsius. This range suits most indoor and outdoor commercial environments. The white finish provides a neutral base for custom branding. Technicians can encode both chips using standard desktop encoders. The dual-frequency architecture provides a future-proof path for expanding security systems.
