kandi X-RAY | card-swipe Summary
[Travis] A utility for detecting CC track inputs from streaming character data and for extracting data from them. A credit card magstripe contains a string of data representing a composite of account details. A card present transaction (which gives you a better retail percentage on your transaction fees) generally consists of setting a flag and passing along this data, which has strict regulations on them preventing them from ever being saved to disk. Normally a magstripe is just a keyboard as far as the OS knows, which often leads to tedious PC POS interfaces where you click into a field and then swipe the card, your other option is to build an input sniffer which allows you to scan time restricted character buffers for track data patterns, so you can react/generate events/whatever. So that’s what this is, you plug keystroke input into it, it reacts whenever it sees a cardswipe. In addition it can use bin ranges on the account number to determine account type and issuer.

QUESTION
I'm working on iOS App with a card-swipe function like Tinder. I have an array with cards. I want to integrate the possibility to flip the card to get more information.
...ANSWER
Answered 2020-Nov-01 at 21:23That is because your @State var back
is for the array.
If you want to control each card you need a CardView
with an @State var back
for each card.
I put some sample code below. A minimum reproducible example is preferred so we don't have to recreate struct
