DO RFID TAG · RFID keyfob manufacturer
Your system. Your branding. Our RFID keyfob range.
We manufacture RFID keyfobs for access, membership and identification projects. Choose from LF proximity fobs, HF system credentials, phone-readable NFC keychains and printed epoxy designs, then build the chip and marking options around your project.
Replacing credentials for an existing installation? Start with the reader and chip requirement. Developing a branded keychain? Start with the shape, artwork and intended use. We bring those choices into one product configuration for sampling and supply.
Find your starting point
Which keyfob should you look at first?
Choose by the job you need the fob to do. For an existing access system, its reader and credential requirements lead the choice; for a new phone interaction or branded design, start with the intended use.
| Your requirement | Start with | Check for your project |
|---|---|---|
| A 125 kHz access-control credential | LF ABS keyfobs | The reader, exact chip and credential format. |
| A 13.56 MHz access-control credential | HF MIFARE / DESFire options | The specified chip family, variant and system configuration. |
| A phone opens a web or contact link | NTAG213, NTAG215 or NTAG216 | The complete NFC record and the intended phone interaction. |
| Cryptographic tag authentication | NTAG424 DNA keyfobs | Key setup, the planned secure dynamic message and backend verification. |
| A logo-led or shaped keychain | Custom printed epoxy keyfobs | The outline, artwork, marking area and chosen chip. |

RFID keyfobs we supply
A compact housing can carry different RFID technologies. Our range gives you physical products to compare, with chip configurations selected for the phone, reader or application that will use them.
13.56 MHz · Reader-based systems
HF RFID keyfobs for your access installation
Our HF range includes MIFARE Classic 1K and 4K-related product options, MIFARE Plus 2K/4K, and DESFire configurations listed in our printed epoxy range. Choose the credential your system specifies, then compare the housing, logo and numbering options.
A replacement order starts from the existing credential specification. A sample can then be tested on the actual reader and application before you issue the batch.
Explore DESFire configurations in our epoxy range. The detailed HF table below includes the other specified configurations.
LF · 125 kHz
ABS proximity keyfobs
A molded keyring product for a specified LF reader. Our proximity range includes TK4100, EM4200, EM4305 and T5577 options, with housing colors and logo marking available by model.
Choose this range when the installed system calls for LF credentials. A familiar exterior can make distribution simple, while printed identifiers help your team organize issued fobs.

NFC · Phone interaction
NTAG key fobs
Use a carried NFC product to open a contact page, campaign or other web destination on a compatible phone. We offer NTAG213, NTAG215 and NTAG216 keyfob options so the selected chip can match the planned record.
Add your logo or number to a molded format, or continue to the printed designs below when artwork is central to the product.

Custom printed epoxy keyfobs
For a brand-led keychain, our epoxy offering combines shaped designs and double-sided CMYK artwork with NFC functionality. Choose the visible design first, then coordinate a shared web link or individual records with the printed information.
A membership design can pair each printed number with its record. A promotional batch can carry one common campaign link behind the same artwork.

NFC · Authentication projects
NTAG424 DNA keyfobs
Our NTAG424 DNA keyfob provides a physical format for projects using cryptographic tag authentication. Available options include housing colors, logo printing, laser numbering and QR codes.
Select it alongside the key configuration and verification service used by your project. The housing and identifiers can then carry the same brand presentation as the rest of your program.

HF · System credentials
Already using MIFARE or another HF system?
The system’s credential specification leads this selection. We supply several HF options; the same frequency alone does not make them interchangeable.
| Required credential | Our product option |
|---|---|
| MIFARE Classic 1K | MIFARE Classic 1K key fobs |
| F08 / 1K-compatible configuration | RFID 1K F08 key fobs |
| S70 / 4K-compatible configuration | RFID S70 4K key fobs |
| MIFARE Plus 2K / 4K | MIFARE Plus key chains |
| DESFire configuration | DESFire options listed in our epoxy range |
For a replacement order, begin with the reader model or existing chip and credential specification. Evaluate the selected sample on the intended reader and application; the system administrator then enrolls matching fobs and assigns the users’ permissions. This connects the product choice to the system in which you will issue it.
We list F08 and NXP MIFARE Classic as distinct options. Matching nominal frequency or memory does not establish compatibility with every system; the specified credential and the sample test determine the selection.
Build your product configuration
Make the fob recognizable, useful and ready for your project
Available processes follow the selected housing and model. These options help define the finished product; they are not a promise that every process is available on every material.
| Order item | Available options | Product basis |
|---|---|---|
| Housing and outline | Molded ABS, shaped printed epoxy, and silicone or wooden design options. | Choose the actual housing, ring attachment and chip together; material choices follow the selected design. |
| Color | Standard housing colors and custom color matching for selected models. | Our Classic 1K and NTAG213 molded ranges list color options; a custom color is agreed for the chosen product. |
| Logo and artwork | Screen printing on selected LF ABS models; pad, screen or UV printing on the listed NTAG424 ABS fob; double-sided CMYK in the epoxy range. | Match the process to the model and its usable marking area. |
| Numbers and codes | Printed serial numbers, QR codes and laser-marked identifiers where offered by the model. | Define which visible fields vary across the order and how they relate to the digital record. |
| NFC records | Blank delivery, a common URL/NDEF record across a batch, or individual records coordinated with printed IDs. | Ordinary NFC records and a managed access credential use different configuration processes. |
| Packaging | Bulk packing, individual polybags, retail presentation or branded boxes, according to the selected order. | These choices are listed for our NTAG213 model; packaging for other configurations is agreed with the order. |
A printed number, a chip’s factory identifier and an application’s member record are different fields. For individually identified orders, defining their relationship gives your team a usable delivery specification.
From a sample to a batch
Bulk Orders, Samples & Customization
You can order an existing configuration, develop a printed design, or specify an encoded and numbered batch. The quotation brings the chosen product, quantity, sample requirements, availability and delivery schedule into the same order.
Existing-model orders
Choose the model, chip, color and quantity. Current availability is checked for that configuration at quotation time. Minimum quantities can vary with the chip, housing and customization; we do not apply one MOQ or lead time to the entire range.
Custom designs and samples
We can arrange standard or customized samples, including a printed prototype or pre-production sample for the selected project. Review the artwork, handling and actual phone or reader interaction before production. The quotation sets out the sample arrangement, any charges and the proposed schedule.
Encoded and numbered batches
Choose a shared record or item-specific data, then define the printed number, QR and NFC record that belong to each piece. We can provide UID/encoding data files and arrange packing in an agreed number sequence, helping your team prepare for distribution and issue.
For an individually identified order, agree the required file fields and layout alongside the numbering range and packing sequence. A file may need the chip UID, printed serial number and programmed record; the fields follow the project’s handover requirements. The chip’s factory UID and your customer-defined serial number remain separate identifiers.
Once the configuration, artwork and data are agreed, the quotation confirms the order’s availability and production schedule. The production order records the final product, approved artwork, data fields, packing instructions and agreed schedule.
Work with DO RFID TAG
From a reader requirement or artwork to a sample you can use
We are a China-based RFID and NFC product manufacturer. Our work connects the physical product, its marking and the planned chip or data configuration. That gives brands, distributors and project teams one place to develop the fob they intend to issue.
We keep the chosen construction, artwork and data requirements together as a product specification for sampling and production. Your team can evaluate the finished fob on the intended phone or reader before the order is defined.
Our company introduction and factory gallery show more of our product and manufacturing work. If the project also needs cards, wristbands or labels, explore our custom NFC product range.
