    Looking for Mifare contactless card reader/writer circuit

    Re: Mifare Card Sometimes it makes no sense to do such contactless interface from scratch as sourcing the asic alone is no mean task. Best to buy module/engine if you do not need much qty. Let me know if you need more referral of manufacterer of such OEM boards..
