Still, managing a pile of outdated keycards while trying to modernize your system? Dual-frequency key fobs and cards can bridge the gap between legacy and modern tech. By combining low-frequency (125 KHz T5577) and high-frequency (13.56 MHz Mifare Classic 1K) chips into one compact design, these credentials can operate as both proximity cards and RFID/NFC tools.
At their core, multi-tech fobs and cards are all about versatility – bringing together modern tech and everyday practicality to handle a wide range of needs:
User Convenience: Users access both low- and high-frequency systems with one compact fob or card, making it easier to carry and manage access credentials.
These fobs give businesses the flexibility to handle a variety of tasks, from access control and point-of-sale (POS) transactions to tool tracking, time management, and managing large campus systems. Below are some of the most impactful ways they can be applied.
Dual-frequency fobs and cards are ideal for environments that demand both security and flexibility. The integration of low-frequency (125 KHz) and high-frequency (13.56 MHz) chips allows these devices to support legacy systems (typically reliant on 125 KHz) while also enabling compatibility with modern access control protocols like Mifare Classic. This simplifies system upgrades, allowing facilities to gradually transition from older technologies to more secure, encrypted systems without replacing all existing infrastructure.
In a corporate setting, for example, a dual-frequency fob can grant access to parking garages (low-frequency readers) and secure server rooms (high-frequency readers) without needing separate credentials.
Multi-frequency functionality makes transactions both secure and efficient, by connecting older 125 KHz RFID systems and modern contactless payment technologies that use 13.56 MHz.
This flexibility minimizes disruptions during technology upgrades, allowing businesses to maintain backway compatibility while moving toward compliance with NFC and other modern payment standards. For instance, a convenience store chain with older hardware can introduce contactless payments for high-frequency cards while still supporting existing customer loyalty programs tied to low-frequency systems.
Tracking tools and equipment in workshops and industrial settings becomes far easier with dual-frequency RFID solutions. Combining low- and high-frequency RFID capabilities enables both physical access and digital inventory tracking. This helps prevent unauthorized use, reduces the risk of tool loss, and creates a clear audit trail for accountability.
In an automotive manufacturing plant, technicians can use their RFID-enabled cards to unlock tool cabinets via a low-frequency reader while the high-frequency chip logs the transaction into a centralized tracking system.
Dual-chip access cards can bring modern functionality to legacy timekeeping systems, simplifying employee tracking while integrating with payroll platforms. These cards eliminate the need for redundant upgrades, bridging the gap between existing hardware and more sophisticated software systems.
For example, a distribution center might rely on older 125 KHz systems for clocking in and out while utilizing 13.56 MHz technology to feed shift data into an HR portal for payroll calculations.
Large organizations like universities, hospitals, and corporate campuses benefit greatly from a single credential that can handle multiple systems, buildings, and facilities. A single university-issued access card could open dormitory doors via low-frequency systems and enable high-frequency transactions for library checkouts or cafeteria purchases. This unified approach simplifies credential management for busy administrators and improves convenience for students.
Dual-frequency key fobs offer a smart solution for juggling legacy and modern systems – letting you upgrade without the headache. If you're looking to combine low-frequency and high-frequency capabilities into a single card, AuthorizID can help. We offer dual-frequency key fobs and printable cards designed to support both the low-frequency 26-bit H10301 standard and the high-frequency 13.56 MHz Mifare Classic 1K standard.
