hello, We are developing a product that uses RFID card 125Khz. I need samples of this module ID-12. You can improve the current price for 4 pieces of samples? If the project is approved we will soon be buying in larger quantities to produce our product series. Please send me a quote for 50 pieces and 100 pieces. I hope that your company can help us and we may soon have a partnership with your company to provide these modules to us. Regards, Leandro Felix Managing Partner. I want to receive: Price Payment .
