I am very concerned about the ten-digit finger scan when I next have to enter Thailand. I have a condition called Dupuytren's Contracture and the ring finger and little finger of my right hand are bent into the palm and cannot be straightened. The ring finger of my left hand is also bent, but not so severely, at a ninety degree angle. I can probably scan that one, but with some difficulty. What is immigration going to do when I cannot scan all ten fingers?
