As a countermeasure to card fraud caused by copying of the magnetic strip ("skimming"), there is at present an ongoing migration in the industry toward IC cards (Smartcards). When creating practical authentication software, a high performance 200 MHz class MCU is necessary for data coding and decryption.
The ePOS system that Renesas proposes combines the AE series that is specialised for coding and decryption with 16 or 32 Bit MCUs specialised for system control, in order to realize a tamper-proof high performance low cost system.

This system diagram only shows a sample configuration. Refer to the data sheet, etc. for performance and other attributes. Reproduction prohibited.
