Looking for help picking the best microchip for my device

[JoMe_4782596]

Hi,

Me and my company are trying to develop a contactless payment wallet the size of a thick credit card.

What would be the microchip to use for such, considering all it would need to do is interface to unlock the device and with the nfc chip to conduct payment transactions.

Hi,

PSoC 6 device family devices have very small form factor, low power and supports all kinds of communication like SPI, I2C, IART, I2S, BLE.

What is the RAM and FLASH required for your application?

You can go through the folowing two family datasheets:
