If you need to lay the card on the sensor because it has to be close enough to read the NFC's weak signal, and the user holds it up too far away, that's not faulty implementation, it's the user not following instructions. Sometimes the user is just doing things wrong.Near Field Communication. Near, not touching. If you have to get closer than 4cm the power on reader is set too low.
User interfaces are like jokes. If you have to explain it, it's not a good one.
So our two options are:
1) Get every single person who lives or visits here to mush their card against the reader.
2) Increase the power of the reader excitation coil.
Hmmmm. Let's pick the easy one and do option 2. Did that at a parking garage entrance once. It would read the card 3-4 feet away. You didn't even have to roll down your window.
Increasing the power to that level would require a license to operate each device from Industry Canada as it would exceed the allowable power without an operating license.
