[rdv4] storing tags in reader mode
is it possible to store tags UIDs to the internal memory in reader mode and download the collected UIDs?

Re: [rdv4] storing tags in reader mode
... define internal memory?
In bigbuff, sure, will disapper if you don't have battery or executing other commands which may clear bigbuff.
in arm flash, depends if you have the large 512kb mcu. Then you could add command to write to unused flashmem and retried whenever.
if you are a lucky owner of RDV4, its just a question of writing to the new onboard memory, look into @bogito's standalone mode which collects pwds that way.
For even more ideas, with RDV4. it would also be possible to have a sim card in simcard module and use that as ondevice external storage. No functionality exists yet. Wouldn't be too hard, its all prepared for such solution.

Re: [rdv4] storing tags in reader mode
Cool, you can also look standalone mode for @cjbrigato vigikpwn, it also uses the new onboard flashmem to write/read.
The onboard flashmem is used in a few places already, fastcheck mifare, lf config, t55xx check, etc..
Remember that flashmemory is different from ram. It wipes with setting memory to 0xFF, then flip bits to zero when programming.
the smallest size of wipable memory is 4k sections. There 16 sections / page. And 4 pages. So fiddle with page0,1,2 but never page 3 since it is reserved for dictionary files, configuration data, etc.
