Help! I borrowed a friends suica card and I got it mixed up with another. I need to return their suica (they want to keep it for memories).
One card is 9 years old and the other one is more new about 3 years old.
The only thing I can see is different is on one card the serial number on the top left starts with PD the other cards serial number is just numbers.
Does anyone know how to tell the difference? Or if you bought a suica card recently does your serial number begin with numbers or letters?
