RFID Tag UART Based Emulator

Hi.

I need to make a RFID Tag Emulator which can take the ID as an input from Serial Port and Transmit the data through Coil (RF). So a RFID reader can read the ID which is coming from Emulated Tag.

I found some projects which are MCU based. I am mainly looking for a ready-made Chip which can take the ID from UART and Transmit through Coil over RF ....

Any advise please?

Regards.

It seems that AMS Austria has proposed a tag chip AS3953 fitting your need. Its datasheet can be found via the following website: http://www.ams.com/eng/Products/RF-Products/RFID.

Hi Streamlet.

Thanks for your message. Actually I am looking for a chip to emulate 125KHz RFID Tag. Seems AS3953 is for NFC (13.56MHz). Do you know any chip for 125KHz?

Regards.
