PIC Project: NFC Payment System
NFC Payment System adalah projek yang membaca nilai duit di dalam Mifare Tag. Sistem boleh menambah nilai duit di dalam Mifare Tag. Kemudian apabila pengguna membelanja nilai duit tersebut, sistem akan menolak baki duit di dalam Mifare Tag tersebut.
Di dalam Admin Mode terdapat setting-setting iaitu menukar password, menukar masa dan tarikh, on/off LCD backlight serta check balance dan add balance mifare tag.
Skematiknya adalah seperti berikut.
PCB komponen layout nya adalah seperti berikut.
