White 125 kHz Hitag2 256-Bit RFID Access Control Card
DAFTags 125 kHz Hitag2 RFID access control cards are blank contactless smart cards for access control, time attendance, parking, ticketing, and identification systems. The Hitag2 chip provides 256-bit memory and a 32-bit unique serial number.
The card can be custom printed with a logo, text, code, or other required information and encoded for the project. Reader compatibility, chip type, security settings, and card craft should be confirmed before production.
Why Trust Us?
- Not every 125 kHz card uses the same chip: Hitag2, EM4100, T5577, EM4305, and other low-frequency cards are not interchangeable in every reader. Confirm the installed system before selecting the chip.
- Access-control software may require a specific ID format: The card has a 32-bit unique serial number, but the format and sector data must match the access system or time-attendance software.
- Security settings are only useful when the system supports them: The chip supports user-defined write protection and encrypted data transmission, but the reader and software must implement those functions.
- Custom card projects need production control: Logo, card number, barcode, magnetic stripe, and encoding details should be confirmed before the batch starts to avoid reprints.
- Replacement cards must match existing users: When adding cards to an installed access system, the chip, frequency, and data format should match the current card population.
What Is a Hitag2 Access Control Card?
A Hitag2 access control card is a 125 kHz contactless smart card used to communicate with compatible readers and grant access to buildings, parking areas, or controlled systems.
The chip contains 256-bit memory and a 32-bit unique serial number. It is intended for non-financial applications such as access control, time attendance, identification, parking, and low-frequency card systems.
Key Features
- Hitag2 125 kHz Chip: Low-frequency RFID chip for compatible access-control readers.
- 256-Bit Memory: Provides storage for access or identification data, depending on the system design.
- 32-Bit Unique Serial Number: Each transponder carries a unique ID for identification.
- User-Defined Write Protection: Supports write-protection settings when configured by the system.
- Encrypted Data Transmission Possible: Encryption depends on the reader and software used with the card.
- Custom Card Production: Printing, numbering, barcode, magnetic stripe, signature panel, and encoding options are available.

Reader and Chip Compatibility
The reader must support 125 kHz Hitag2 cards. A reader built for EM4100, T5577, or 13.56 MHz cards may not read this chip even if it uses the same card size.
Send the reader model, current card type, required ID format, and security settings before ordering. Test a programmed sample in the live access system before approving bulk production.
Card Craft and Encoding
The card can be supplied blank or customized with printed and encoded data. Confirm the artwork and data format together so the card is ready for use when it arrives.
- Offset, silkscreen, inkjet, or digital printing
- Logo, text, barcode, or QR code
- Magnetic stripe
- Signature panel
- Hot foil, silver or gold background
- Anti-fake feature
- Card encoding
Procurement Notes
Before production, confirm:
- Reader brand, model, and supported chip type
- Required ID number, write protection, and encryption setup
- Printing, numbering, barcode, magnetic stripe, and encoding details
- Card material, thickness, and finish
- Read distance with the installed reader
- MOQ, sample policy, packaging, and production schedule
FAQ
Will these cards work with our access control reader?
Only if the reader supports 125 kHz Hitag2. Send the reader brand and model before ordering so the chip can be checked.
Are the cards supplied blank?
The standard item is listed as a blank RFID card. Encoding can be discussed for access-control projects.
Can the cards be printed with our logo?
Yes. Offset, silkscreen, inkjet, and digital printing options are available. Confirm the artwork file and card finish before production.
Can the cards be encoded before shipment?
Encoding can be discussed. Provide the required ID format, write-protection settings, and any encryption requirements for confirmation.
How much memory does the card have?
The Hitag2 chip has 256-bit memory and a 32-bit unique serial number. The usable data layout depends on the access system.
Can I request samples?
Sample availability depends on the current production schedule. Test a programmed sample in the actual reader before approving bulk production.
