Hi. Of course the cost of the chips (if that is what you mean) are highly influanced by the volumes. I would suggest that you also look at modules, especially if you are early in your design. Two good sources are www.sonmicro.com for modules and www.3alogics.com for a inexpensive 13.56MHz chip.

There are of course many others and you can look up their prices in Digikey:

For example:

TI S6700
TI TRF7960 and TRF7961 (13.56MHz)
Atmel U2270B (U2280??) - Atmel has the u3280/u9280, but sells it in large quantities
Cypress CY8C0104/05 chip/module
MFRC500 from Philips
SLF9000 from Infineon
tms3705a from ti
HTRC1100 1T Philips
HT079231 NXP Hitag
