CR80 TK4100 Blank 125khz Proximity Cards

Description:

TK4100 is a CMOS integrated circuit for use in 125KHz read only RFID card.  It is compatible with EM format.

Features:

64 bit memory array laser programmable

Several options of data rate and coding available

On chip resonance capacitor

On chip voltage limiter

Full wave rectifier on chip

Large modulation depth due to a low impedance modulation device

Operating frequency 100-150 KHz

Very small chip size convenient for implantation

Very low power consumption

Operation:

modulation coding (Type code, data rate is RF/64). Only if the chip produce at both ends of external coil induced voltage >=3.5Vpp and the clock rate is 125Khz , it will start working NFC CARD

The technology has the advantage of information exchange do not need to have any contact between card and card reader. Card storage capacity generally between 256 b and 72 KB, at present the most popular technology of Legic,, Mifare Desfire, iCode and HID class and so on, also follow ISO14443 from A&B communication protocol chip. Usually used for access control to collect fees, bus, subway etc. Contactless IC card chip made by PHILIPS/NXP company with the Mifare classic S50 S70 or chips, so a lot of people traditionally called contactless IC card "M1 card" combo cards
