I am looking for a very low cost reader/label combination for communication with high volume consumable products. The read distance must be at least 30mm.
Dear David Henke, I am not sure you would have a problem with the MFR522 and the MIFARE Ultralight, the distance will depend on the antenna size and tuning but typically is 50mm , just to let you know that this reader is not recommended for new designs we recommend the MFRC630, please check the following links with the readers and their capabilities( NFC Reader ICs|NXP ), I do not think that your reading distance will be a problem with any of them as long as you reader have a good antenna design I will leave here the antenna design guide for this device (https://www.nxp.com/docs/en/application-note/AN1445_An1444.zip ) and if you choose other reader please check in the documentation section of the selected reader for the antenna design guides.
Have a great day !!
Thank you, Jonathan, for your reply.
I was hoping that someone had already tried using the RC522 RFID reader module to read an ultralight label and could tell me the read distance. I like this module because it has the antenna integrated on the PCB which only contains the MFRC 522 chip and antenna tuning component. I believe it will be hard for me to find a lower cost combination of Mifare reader/writer module and label. Has the MFRC630 chip ever been made into a low cost reader/writer module with integrated antenna? Also, is the MFRC 522 chip going to be unavailable soon, and that is why it is not recommended for new designs?
