Frequently Asked Questions About Proximity & Access Credentials (125kHz)
What are 125kHz proximity credentials?
Proximity credentials are passive RFID-based cards, key fobs, or tags that operate at 125kHz. They store a unique identification code and transmit it wirelessly to a compatible reader, granting or denying access to a secured area.
What types of 125kHz proximity credentials are available?
ID Enhancements carries a wide range of 125kHz credentials, including cards and key fobs compatible with HID, Honeywell, Kantech, KERI, Paxton, AWID, DoorKing, Indala, Farpointe, Keyscan, ZKTeco, Allegion, Cansec, Rosslare, and many other leading brands.
What does 125kHz mean?
125kHz refers to the radio frequency at which the credential communicates with its reader. It falls in the low-frequency RFID range and is one of the most widely used standards for traditional access control systems.
What industries use 125kHz proximity credentials?
These credentials are commonly used in offices, schools, healthcare facilities, warehouses, manufacturing plants, apartment communities, and commercial buildings.
Are 125kHz credentials the same as prox cards?
Yes. "Prox card" is industry shorthand for a proximity card, and most traditional prox cards operate at 125kHz.
Do 125kHz credentials require a battery?
No. They are passive RFID devices and require no battery.
How 125kHz Proximity Credentials Work
How does a proximity credential work?
The reader emits a low-power electromagnetic field. When the credential enters that field, it harvests energy, powers its internal chip, and transmits its identification number back to the reader.
How close does the credential need to be to the reader?
Most standard credentials read between 3 and 6 inches, while long-range credentials can read much farther depending on the technology used.
What is a facility code?
A facility code is a numeric identifier programmed into a credential. It helps the access control system distinguish credentials from different organizations and credential groups.
What is a card number?
A card number is the unique identifier assigned to an individual credential and user.
What is the Wiegand format?
Wiegand is a common credential data format used by many access control systems. Common formats include 26-bit, 34-bit, and 37-bit configurations.
Product Types & Formats
- Clamshell Cards
- Printable PVC ISO Cards
- Printable ISO Cards with Magnetic Stripe
- Key Fobs
- Adhesive Tags
- Silicone Wristbands
What is the difference between an ISO card and a clamshell card?
ISO cards are credit-card thickness and designed for photo ID printing. Clamshell cards are thicker, more durable, and often provide increased read range.
Can I print photos and graphics on proximity cards?
Yes, on printable ISO cards. Clamshell cards are generally not designed for direct printing.
What is a key fob credential?
A proximity key fob is a compact credential that attaches to a key ring and functions similarly to a proximity card.
What are RapidPROX® credentials?
RapidPROX® is the trademarked credential brand of ID ENHANCEMENTS, INC. Manufactured in the USA and backed by a lifetime warranty, RapidPROX® credentials provide dependable performance, broad compatibility, and rapid production times.
What are EconoPROX® credentials?
EconoPROX® offers a cost-conscious alternative for organizations seeking dependable credential performance while reducing overall credential costs.
Compatibility
How do I know which credential is compatible with my system?
Compatibility depends on the reader technology, credential format, facility code requirements, and access control platform in use.
Can I use compatible credentials instead of OEM credentials?
In many cases, yes. Compatible credentials are often designed to work seamlessly with existing systems while helping reduce costs.
Are 125kHz credentials compatible with older systems?
Yes. One of the reasons 125kHz credentials remain popular is their broad compatibility with legacy access control infrastructure.
Security
How secure are 125kHz credentials?
125kHz credentials remain a dependable technology for many facilities. Organizations requiring advanced security may also consider encrypted smart card technologies.
Do proximity credentials store personal information?
No. Traditional 125kHz credentials generally store identification data rather than personal user information.
Ordering & Customization
Many credentials can be supplied with custom facility codes, sequential numbering, logos, slot punches, barcodes, magnetic stripes, and custom printing options.
125kHz vs. Other Technologies
Are 125kHz credentials still relevant today?
Absolutely. While newer technologies continue to gain market share, 125kHz credentials remain one of the most widely deployed access control technologies due to their affordability, reliability, and extensive installed base.
Can I mix 125kHz and 13.56MHz credentials?
Yes. Multi-technology readers allow organizations to support both credential types during migration projects.
