NFC Readers for POS, MPOS and SmartPOS

The PTX100R marks a breakthrough in NFC system performance, power and size.

The PTX100R is fully compliant with the specifications of the latest EMVCo 3.0 standard for contactless payments. It is supplied with an application-ready EMVCo 3.0 L1 interface. The Panthronics product includes a set of facilities which makes the integration of a third-party EMV L2 stack fast and easy. It also provides rich debugging capabilities allowing for rapid prototyping.

Benefit from our patented DiRAC technology which enables the NFC to drive output power of up to 2W directly to the antenna while achieving sensitivity of -80dB.

The PTX100R is in mass production now.
