Looks more like a model of a small resistor. Only the tiniest THT resistors and inductors have this shape because normal-sized ones’ wire-wound or vapor-deposited cylinders are long enough to get both terminals encased in resin separately as opposed to dunking all of it into a blob. And resistors of this size can have their entire datasheets printed onto them, color bands are again just a space-saving measure. Not to mention, the only reason it would need to be this bulky is power rating, and a sphere is the least ideal option for heat dissipation.



Some banks issue stickers for phones without NFC. It’s another physical card but contactless only and very thin (probably with an aluminum strip antenna).
