A Guide to RFID Key Fobs
RFID key fobs provide convenient, contactless access to offices, commercial buildings, gated facilities, and secured entrances. These compact credentials communicate with electronic readers to identify authorized users without requiring traditional keys.
Available in original manufacturer and generic-compatible versions, key fobs can be supplied with specific credential formats, facility codes, and identification numbers. Some models also offer custom printing for company logos and identification.
How RFID Proximity Key Fobs Work
Most traditional proximity key fobs operate at 125 kHz and use passive RFID technology, requiring no batteries. When presented near a reader, the fob transmits its identification data for verification by the access control system.
Not all 125 kHz key fobs are interchangeable. Compatibility depends on the reader's supported technology and credential format.
HID Prox III Key Fobs
HID Prox III key fobs are widely used for commercial access control. Available in multiple credential formats, they can be ordered with specified facility codes and identification numbers.
OnlineRiver offers original HID credentials and lower-cost generic-compatible alternatives, with options for plain or custom-printed key fobs featuring logos, text, and numbering.
Generic-Compatible Key Fobs – Packs of 100
Generic-compatible proximity key fobs provide an economical alternative to original branded credentials. They can operate with supported HID Prox III systems when supplied with the correct technology and programming format.
Lower prices and faster production make these fobs attractive for businesses purchasing replacement credentials or outfitting multiple facilities. Available in packs of 100, with original branded versions also offered.
Rosslare-Compatible Proximity Key Fobs
Rosslare-compatible key fobs are designed for readers supporting 125 kHz EM proximity technology. Available in ring and twist styles, these factory-encoded credentials may include external numbering for identification.
These fobs are not necessarily interchangeable with HID Prox III credentials, even though both operate at 125 kHz.
Credential Programming and Compatibility
Access control systems may require specific programming information:
• Credential Format: Defines the identification data structure, such as 26-bit or 37-bit.
• Facility Code: Identifies a designated group or installation.
• Identification Number: Assigns a unique number to each credential.
• Number Range: Specifies the sequence required for an order.
The correct credential technology and format must match the existing reader and access control system.
Custom Printed RFID Key Fobs
Custom printing allows businesses to add logos, text, and identification numbers to their proximity credentials. Plain key fobs are also available for customers who do not require external branding.
Printing options, minimum quantities, and production times depend on the selected product. Electronic credential programming is separate from surface printing.
