Hi @eskimo , thanks for the update.
iOS has built-in support for standard USB smart cards (via USB CCID), so the easiest way to achieve your goal is to change your hardware to support that standard.
This is interesting. The hardware has USB CCID. Should we use TKSmartCardSlotManager for this? I wrote a basic swift file using TKSmartCardSlotManager
import CryptoTokenKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Start observing smart card slot state changes
startObservingSmartCardSlotStateChanges()
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
// Stop observing smart card slot state changes when the view disappears
stopObservingSmartCardSlotStateChanges()
}
func startObservingSmartCardSlotStateChanges() {
DispatchQueue.global().async {
if let slotManager = TKSmartCardSlotManager.default {
while true {
let slotNames = slotManager.slotNames // No need for optional binding
for reader in slotNames {
slotManager.getSlot(withName: reader) { slot in
guard let slot = slot else {
print("Slot for reader \(reader) is nil")
return
}
let state = slot.state
if state.contains(.cardPresent) {
// Smart card is present in the slot
print("Smart card is present in slot: \(reader)")
// Example: Communicate with the smart card
if let card = slot.makeSmartCard() {
card.beginSession { session, error in
if let error = error {
print("Error beginning session with smart card: \(error.localizedDescription)")
return
}
// Session started, now you can communicate with the smart card
}
}
} else if state.contains(.empty) {
// Smart card slot is empty
print("Smart card slot is empty: \(reader)")
} else {
// Unknown state or other state
print("Smart card slot is in an unknown state: \(reader)")
}
}
}
// Poll every few seconds
sleep(5)
}
} else {
// Handle the case where 'default' returns nil
print("TKSmartCardSlotManager.default is nil")
}
}
}
func stopObservingSmartCardSlotStateChanges() {
}
}
Do you think this is correct implementation? Your feedback would be helpful
Thanks in advance
