Application: 

access control, consumption, membership card management, sauna, entertainment, clubs and other fields.

Optional process:

thin card, thick card, smooth / matte / frosted surface, bronzing / silver, gold / silver bottom, UV oil, laser code, spray code, signature strip, scraper, film adding, drilling, etcThe chip fully compatible with em4200 is tk4100. The performance, purpose and use method of tk4100 are exactly the same as em4200. However, since em4200 is an original imported chip, there will be many additional charges such as taxes, so the price is relatively high. TK4100 is produced in Chinese mainland, with low production cost and strong competitiveness. Therefore, in more and more systems, TK4100 chips are used instead of EM4200.
