How is it a card reader like you see in a shop or market stall can read a card but flipper cant, surly the flipper could read like the card reader then emulate it even if it was one time, A card reader even a portable one reads the code the date and pin thats why it can do contactless
Those readers are far more complex and expensive then you realize. Those device also require an internet connection which the Flipper does not have.
One last thing you must take into account when talking about anything Flipper related is that the firmware on the Flipper is still beta. Features should be more robust once the Flipper firmware hit’s the V1.0 level.
