And the voltage stated 12V wow its so high :S currently im using Li-Po 11.1V which is solely used to supply power to SPG-30K http://www.cytron.com.my/viewProduct.ph ... R/MWJw1Vo=
so is the voltage or current sufficient if i pull out the power from the 11.1V Li-Po for this RFID reader? im scared that the RFID reader will not operate due to too low voltage something like this...

the Wiegand RFID reader stated there that it iss compatible with 125kHz RFID tags. But the problem now is that i need a much smaller RFID tag http://www.cytron.com.my/viewProduct.ph ... FID%20Card this one is too big already...i mean the surface area.. is there any place we can find a much smaller surface area RFID card? it is best if i can have half size of the RFID card that cytron sells.. we need to use also 125kHz right?
