I recently buy the ACR122U-A9 and 13.56MHz RFID Proximity ID Card Key Tags Writable rewritable CUID fob tag, Compatible with MIFARE Classic 1K on Amazon. I installed MWT V.1.6.8424.424.63 and it work for like 4 tag, now it just say that it cannot read the card or it stops at like 63 on 64. Can anyone help? I'm really not that great with technology
Hello sir,
Thank you for working with our devices.
Regarding the use of the ACR122U-A9 , I noticed that in the official page it mentions that this reader isn't recommended for new designs. My recommendation is to migrate to a recommended and supported one.
Regarding the MW installed, would you mind clarify where did you get this middleware since I wasn't able to find it in the official page.
I would like to understand what do you mean that the tags that are compatible with MIFARE Classic are able to work like 4 tag. MIFARE Classic cards can only support ISO14443-3 commands, please take a look at the Datasheet for a proper command description.
If you could provide more information about your project I might be able to provide a better recommendation since MIFARE Classic cards aren't recommended either due to security reasons.
