Nundprox RFID cards are categorized in three parts based on frequency spectrum Nundprox M, Nundprox K, Nundprox U.
NundProx M, the 13.56MHz is high frequency range smart card based on an Advanced Encryption Standard (AES) for contactless cards with ISO/IEC 14443 Type A including all parts.
Part 1 | ISO/IEC 14443-1:2018 | Physical characteristics |
Part 2 | ISO/IEC 14443-2:2016 | Radio frequency power and signal interface |
Part 3 | ISO/IEC 14443-3:2018 | Initialization and anti-collision |
Part 4 | ISO/IEC 14443-4:2018 | Transmission protocol |
These Cards are available as Type A and Type B communicating at frequency 13.56 MHz. The main differences between Type A and Type B are based on modulation methods, coding schemes (Part 2) and protocol initialization procedures (Part 3). The transmission protocol for Type A and Type B cards are as per part 4. The transmission protocol specifies data block exchange and related mechanisms are Data block chaining, Waiting time extension Multi-activation. ISO/IEC 14443 uses PCD – proximity coupling device (the card reader) and PICC- proximity integrated circuit card components. The cards are available using the material PVC, ABS & PET as cards, fobs and tags
NundProx K, the 125KHz is low frequency range ISO proximity cards using Amplitude Shift Keying (ASK) & Frequency Shift Keying (FSK). It uses the several options of data rate and data encoding like Manchester 32 & 64 RF clocks per bit with the Bi-phase 32 & 64 RF clocks per bit respectively. The Phase Shift Key PSK 16 RF clocks per bit (subcarrier RF/2) and Frequency Shift Keying (FSK2P 50RF clocks per bit. The cards are available using the material PVC, ABS & PET as cards, fobs and tags.
NundProx U is an ISO18000-6C/EPC Gen2 protocol series of RFID card with the operating frequency range of 860-960MHz and Electronic Product Code (EPC) memory of 128 bit & Tag Identification (TID) memory of 96 bits. The chips used are Imping Monza 4QT & Alien H3. These identification units are available as cards, fobs, stickers and ant-metal tough tags.

Nundprox RFID cards are available for multiple applications with standard encryption. Biometric cards are under testing and will be launched soon.
