flexDF [DESFire EV1 8k]

The flexDF is one of our next generation, high performance, RFID and NFC compliant transponders. The flexDF is coated in USP Class VI, ISO 10993 tested biopolymer which gives it an extremely thin profile and semi-flexible structure suitable for installation just about anywhere.

It can be read and written with devices using 13.56MHz RFID and all NFC compatible readers and writers, including USB devices and many NFC-enabled Android smartphones. They are rewritable and can store data such as your business card (vCard), medical and allergy information or emergency contact details.

Installation procedure

Please be aware if you're wanting a professional to do the install, there is no need to buy the Flex Implant. Simply purchase a KSEC Cyborg package of your choosing and select the Cyborg Centre for your installation then book in your professional installation.

– Do not install under any gripping surface (e.g. no palm side installations) – Do not install atop or parallel to any joints (flex device are only “semi-flexible”) – Incise skin with scalpel, making 9mm wide incision – Lift/separate dermal layer using elevator tool – Remove dermal tools from installation site – Slide flexNT under skin by hand, do not use gripping tools – Suture to close wound, do not pierce flexNT with suture needle


MIFARE DESFire EV1 (MF3ICD(H) 21/41/81), a Common Criteria (EAL4+) certified product, is ideal for service providers wanting to use secure multi-application smart cards in public transport schemes, access management or closed-loop e-payment applications. It is fully complies with the requirements for fast and highly secure data transmission, flexible memory organization and interoperability with existing infrastructure. MIFARE DESFire EV1 is based on open global standards for both air interface and cryptographic methods. It is compliant to all 4 levels of ISO/IEC 14443A and uses optional ISO/IEC 7816-4 commands. Featuring an on-chip backup management system and the mutual three-pass authentication, a MIFARE DESFire EV1 card can hold up to 28 different applications and 32 files per application. The size of each file is defined at the moment of its creation, making MIFARE DESFire EV1 a truly flexible and convenient product. Additionally, an automatic anti-tear mechanism is available for all file types, which guarantees transaction-oriented data integrity. With MIFARE DESFire EV1, data transfer rates up to 848 kbit/s can be achieved, allowing fast data transmission.

The main characteristics of this device are denoted by its name “DESFire”: DES indicates the high level of security using a 3DES or AES hardware cryptographic engine for enciphering transmission data and Fire indicates its outstanding position as a fast, innovative, reliable and secure IC in the contactless proximity transaction market. Hence, MIFARE DESFire EV1 brings many benefits to end users. Cardholders can experience convenient contactless ticketing while also having the possibility to use the same device for related applications such as payment at vending machines, access control or event ticketing. In other words, the MIFARE DESFire EV1 silicon solution offers enhanced consumer-friendly system design, in combination with security and reliability.
