  1. you sure those are the right format for cloning your campus’ proximity card? There are multiple standards using 125khz, and the amazon page you linked is for EM4100 with a read-only ID

  2. I did find EM4100 stickers that claim a 0.3mm thickness: https://www.amazon.com/dp/B07PCJKPZZ/ref=cm_sw_r_cp_api_i_z5.QDbB9Z2XKW

  3. If your campus uses HID Prox (incredibly common), you’ll want to look for T5577 which can emulate HID Prox, effectively cloning them.

  4. Ultimately your question is about form factor, and aside from the required structure or thickness of the rfid chip/antenna, what is available is hard to qualify a priori. It’s really a matter of doing a lot of searching across lots of vendors. I would suggest using the words “thin” and “sticker” to get results nearer what you want. Obviously there are lots of pvc card and keychain fob styles available.
