Scan taking too much time or sometime its not scanning card Android

[imrahulpatel]

I added card io for add card by scanning for my app, but I noticed that for an android scan card taking too much time or even sometimes it's not scanning card, I tried so many cards but the same issue happen. below is the code of my app

let config = {
suppressManualEntry: true,
suppressConfirmation: true,
requireExpiry: true,
requireCVV: true,
requireCardholderName: true
}
CardIOModule
.scanCard(config)
.then(card => {
})
.catch((e) => {})

is there anything config params which I need to add ? any help will be appreciated, Thank you
