Hello 👋. I need some advice.

I would like to obtain a blocked NFC and RFID card.

I have been searching for aluminium or lead cards because I understood both materials (better lead material) are the best for blocking the infrared signals.

I was wondering if someone can tell me which brand is the best and most confident for this product. Additionally I want to engrave a design in that card.

Which brand and material is the best? Thank you
