Hell Alexander,

While nRF52 is probably able to emulate EMV compliant "NFC card emulation" device (rather call it "contactless") aka "payment card" it almost certainly cannot pass security certifications required. So unless you target some close loop proprietary solution (where you would certify the device + app) it pretty much cannot be used for payment beside some dummy demos.

Cheers Jan

The nRF52 has NFC that can be used for exchange/retrieval of data.

The nRF52 comes in different package sizes, the smallest is the WL-CSP version. It has the following dimensions: 3.83mm x 3.83mm with a height profile of 0.35mm

Another benefit with the nRF52 is that it can have BLE support. It means that the data in the chip can be updated over BLE, using a phone for instance.
