I need help on the issue of asynchrnous serial data transfer

[Aigneryu]

I need some suggestions on the issue of the asynchronous serial data transferring circuits. A simple, maybe, circuit with low power to detect asynchronous serial data input for a control logic is needed in a low power communication system like RFID. Where can I find examples or introductions?

Hi,

I've been working with 125 kHz, 13.56 MHz and 915 MHz RFID readers.
Which one do you want to use?

Where do you plan to connect your reader to? I connected them to MC AT89C2051,
AVR90S8515, ATmega8515, and to laptops & palmtops.
