White cards, coins, cards, white cards in small M1 card, ID card small coin card processing: the outer diameter size 20mm; 25mm; 30mm; matching Chip: TK4100 chip, TK4101 chip, TK4102 chip, EM4100 chip, EM4200 chip, EM4305, T5577, HT4168,4100D like. Different match different inductance coil, commonly used inductance have 2.85mH, 3.1mH, 3.45mH, 4.58mH, 4.85mH, 4.91mH other common frequency 125kHZ, other frequencies can be modulated 250kHZ, 375kHZ, 500kHZ, 650kHZ, 700kHZ, 1000kHZ etc. We also based on user needs to develop a suitable coil, customers can also provide matching chip to my office, sample processing. In addition, we added the welding sector, soldering chip coil service. It offers shell package, marking, etc. We can also customize according to the needs of users for the coil, customers can also provide chips to our best reading distance of matching coil, sample processing.
