Contactless Technology
Contactless Smart Cards
From MIFARE Classic to DESFire EV3, from 125 KHz to 960 MHz -- we manufacture the full spectrum of contactless smart card technologies for every application.
Contactless Technology Overview
Contactless smart cards use radio frequency (RF) technology to communicate with a reader without physical contact. The card's embedded antenna and microchip enable secure, rapid data exchange with a simple tap or wave gesture.
Cardzgroup manufactures contactless cards across all major frequencies -- Low Frequency (125 KHz), High Frequency (13.56 MHz), and Ultra High Frequency (860-960 MHz) -- using chips from NXP, Infineon, Texas Instruments, EM Microelectronic, and other leading semiconductor manufacturers.
Product Range
Six categories covering every contactless frequency and security level.
