I have read a a lot about the U2270B on here but have a few more questions that I see have not been answered. I am working on a project where I need to read multiple RFID tags constantly. I am using the TK5551 for tags. The question is how does the U2270B handle multiple tags at the output and the input.
 

U2270B is a dedicated chip for 125Khz rfid, and as these RFID chips are read only, they cannot be read in multiples. You may consider design of Mifare with 13.5Mhz.
Cheers
