Re: Android Handheld RFID Reading EPC and User Memory
The Zebra RFD8500 RFID Handheld reader supports Android devices.
However, no RFID Reader can read EPC and USER simultaneously. The air protocol allows access to only one memory bank at a time.
In your application you need to inventory your tags and then individually access the memory banks you want to read.

Re: Android Handheld RFID Reading EPC and User Memory
Thanks Andreas for your response, but I have a question
I already have an RFID handheld reader from another manufacturer that reads both EPC and TID memory banks together .. So that means that reading more than one memory bank is applicable but why there is no way to read EPC and USER memory banks together ? Is it a general thing in RFID readers ?

Re: Android Handheld RFID Reading EPC and User Memory
It is very easy to make duplicate tags with identical EPC. To prevent fraud, some tags feature a silicon serial number, which cannot be changed. This serial number lives in the TID memory, That may be the reason, why some reader software show the TID memory together with the EPC.
Other than EPC and TID, USER memory is not mandatory. Some tags don't have any USER memory at all. It does not make sense to read it everytime.
Probably, you need to write a custom application, that reads EPC and USER memory for every tag and report them back together.

Re: Android Handheld RFID Reading EPC and User Memory
Can I read TID + EPC in a simple step or reading with the Zebra RFD8500 ??

Re: Android Handheld RFID Reading EPC and User Memory
Reading TID and EPC in one go require the tag to support it and typically a vendor proprietary command from the reader.
I don't think the RFD8500 supports that to date.
