Hi, I`m hoping you can help guide me. I want to kill 2 birds (figuratively) with one stone. My son is getting into electronics and very basic coding and i also need something built so i was hoping to get the parts necessary. The gym i represent is doing a series of outdoor sessions and we need to build a portable rfid scanning device for members cards. Our members are equipped with the 13.56MHZ (i think) RFID cards, and we need to be able to scan them and store the data on an sd card if possible so later we can upload it to our centres membership system to record which members attended. And obviously it needs power. Any guidance you could give on the parts i need to order would be fantastic. Thank you in advance.
