I'm trying to enable my ollee Casio to pay since I saw the mod of Matteo Pissani where he extracts and re-coils a debit card chip into a 3D printed face. (idk if links are allowed but you can find their article on medium)
But I'm lazy, so I bought a Curve payment wearable that looked small enough and easily extractable. I thought it would be some kind of sticker like the NTAG213 I received with the ollee board but after extracting it, I found out it is a rigid piece shorter but wider than the sticker.
I tried to put it under the face like the "alternative" sticker position but it is too rigid and thick to fit. And under the backplate it's too far to detect.
I kinda have ran out of ideas, do you have suggestions what to try ?
