NFC Card Problem reading card only after N time

Post by fredkto »

Hello,

I have a problem, i would like to know if someone already encounter this matter.
When I launch my program, the shield read my card perfectly. if i retry in short time it's fine.
But, if I try to read this same card 10 minute after for exemple, it don't read my card.

If i let this card on my shield during 10 minutes, this card is read during 10 minutes.

So my Question : Why after N time my shield wouldn't read my card.

Thank a lot for your answer.

(sorry for my bad english)

I can't think of any reason why this might happen except if there is perhaps a problem with the tag itself? It's not something we've ever seen ourselves with any tags or boards, and this is quite an old design so it's been used and abused a LOT over the years.
