Hi, I am interested to work on this job. I do not understand that why do you want to extend the range? If you are not getting perfect result then get closer to the objects and get results. Any way, what do you need to do? Do you want to design an antenna or whole RFID device? Make it clear for better understanding. If you wish to have discussion, then let leave a reply. Thanks. Chirag

The best and less costly way to increase RFID range is to add a power amplifier and possible design a new antenna, to do that we will need to know the manufacturer and model you are using in this moment. is it not possible to modified the existing design we should design a new reader adapted to meet your needs. The quoted price is for reference only, until we know more information. If you have any questions do not hesitate to contact me, hoping we meet your needs and hear from you soon. Thanks in advance, best regards. Amador G. Montero
