I’ve accumulated a whole lot of these physical OTPs from DBS Bank and since they have been decommissioned and/or no longer working, I figured I should tear it down.

It is a pity that there isn’t a way to replace the battery and that there isn’t – from what I can see – a way to recycle these devices.

I’ll try to pry out the black resin that is hiding the CPU etc and see what it under that. What I was looking to do is to salvage the keypad and display for *something*.
