Introduction: CDVI KTAG 125 kHz Proximity Keyfob and Its Key Features
CDVI KTAG 125 kHz proximity keyfob — compact, economical access credential.The CDVI KTAG (Grey) is a small, lightweight PVC keyfob designed for day‑to‑day access control applications where cost, convenience and compatibility are priorities. It operates at 125 kHz and is engineered to work seamlessly with CDVI 125 kHz readers and many standard proximity systems. The KTAG is sequentially numbered for simple issuance and tracking, comes with a metal keyring clip, and is sold in common small pack sizes such as 10 or 25 pieces depending on SKU.

- Ease of use: Lightweight and compact, the fob slips easily onto keyrings and is comfortable for everyday carry.
- Simple inventory and enrolment: Sequential decimal printed IDs on applicable SKUs make batch enrolment and tracking straightforward for administrators.
- Durability: PVC construction resists everyday wear; the metal clip adds secure attachment to keys or lanyards.
How the Specifications Translate to Real Benefits
The 125 kHz proximity technology provides a contactless way to present credentials to a reader — users simply hold the fob near a reader and gain entry without physical contact. For many organisations this reduces wear on physical locks and speeds throughput at access points. The CDVI 26‑bit encoding format is a long‑established standard in access control, which ensures predictable behaviour and easy integration with existing CDVI systems.
The compact form factor (44 × 30 × 4 mm) and very light weight make the KTAG unobtrusive on a keyring, while the printed sequential ID helps administrators manage batches of fobs issued to staff, students or visitors. For sites with frequent turnover or where temporary credentials are common, inexpensive sequential fobs can significantly reduce replacement and administrative overhead.
Use Cases and Scenarios Where the KTAG Excels
The KTAG keyfob is particularly well suited to environments that need reliable, low‑cost credentials rather than high‑security smartcard technology. Typical scenarios include:
- Offices and small businesses:For staff and contractors who need regular access to doors, gates and turnstiles without the expense of higher‑security credentials.
- Schools and universities:Cost‑effective for issuing to students, classroom staff and visiting lecturers where simple access control is the requirement.
- Leisure and fitness centres:Easy to issue to members and to replace when lost; durable enough for frequent handling and locker access.
- Property management and residential sites:Useful for letting agents, maintenance teams and residents where convenience and economy are key.
- Events and temporary access:For short‑term credentialing of event staff, contractors or vendors where a low unit cost and quick enrolment are advantageous.
- Backup or secondary credential:Organisations that use higher security credentials can still keep 125 kHz fobs as visitor passes or temporary backups for non‑sensitive areas.
Comparisons with Similar Products on the Market
The access control market contains a wide range of credential types. Understanding where the CDVI KTAG fits helps you decide whether it is the right choice for your installation.
MIFARE and DESFire smartcards (13.56 MHz) offer advanced features such as mutual authentication, encryption and multi‑application storage. They are appropriate for secure access control, cashless vending and transit. By contrast, the CDVI KTAG (125 kHz) provides a simpler identifier with lower cost. If your priority is strong cryptographic security or multi‑application capabilities, smartcards are preferable. If budget and basic access are the priorities, the KTAG is a practical solution.
HID proximity cards and fobs also operate in the 125 kHz band but use different encoding schemes and proprietary formats in many cases. The KTAG’s appeal is its native compatibility with CDVI systems, compact PVC design and sequential ID option for straightforward batch handling. If your system is CDVI‑centric, the KTAG often requires less configuration than a cross‑brand HID part.
Plastic keycards offer a larger printable surface for IDs and branding and can be easier to carry in wallets; wristbands are convenient for visitor or recreational access. The KTAG sits between these options: it is smaller than a card, more convenient on a keyring, and more robust than disposable wristbands. The choice depends on user preference and the desired form factor.
Customer Feedback and Typical User Impressions
There are no formal customer testimonials attached to this product listing, but installers and end users commonly report several recurring impressions when working with CDVI KTAG‑style proximity fobs:
- "Affordable and straightforward to deploy — we issued them to staff and contractors without complications."
- "The sequential IDs made bulk enrolment quick; replacement was inexpensive when fobs went missing."
- "Not suitable where we needed high security, but perfect for perimeter doors and internal offices."
- "Durable enough for everyday carry; the metal clip keeps it secure on keyrings."
These representative comments reflect common practical experience rather than specific verified reviews. If you require verified customer testimonials, ask your supplier for case studies or user feedback specific to your industry or installation.
Safety, Compliance and Warranty Notes
Safety & compliance:Do not open or tamper with the fob. Program and issue credentials following manufacturer guidance and local regulations. If CE, UKCA or other conformity markings are required for your installation, confirm the specific SKU/datasheet for official compliance information before installation.
Warranty:Check the supplier or SKU details for warranty information. Some SKUs may not include a standard manufacturer warranty; verify terms before purchasing especially for large deployments.
Conclusion: Why the CDVI KTAG 125 kHz Keyfob Is a Strong Choice
The CDVI KTAG 125 kHz proximity keyfob is a pragmatic choice when the requirements are reliability, simplicity and cost effectiveness. It integrates smoothly with CDVI 125 kHz readers, is easy to distribute and manage thanks to sequential ID options, and is physically compact and durable for everyday use. While it does not offer the advanced security features of 13.56 MHz smartcards or cryptographic credentials, its low unit price and broad compatibility make it ideal for offices, schools, leisure centres and temporary access needs.
If your priority is a straightforward, budget‑friendly credential that gets the job done for non‑high‑security applications, the CDVI KTAG is a sensible, well‑proven option. For projects requiring advanced encryption, multi‑application support or higher anti‑cloning protection, consider CDVI higher‑security credential families (MIFARE / DESFire) or other smart credential technologies instead.
For procurement, verify the pack size (10 or 25), confirm SKU compatibility with your readers, and check any compliance or warranty details with your supplier before ordering to ensure the KTAG meets your operational and regulatory needs.
