YumiPass mobile app incorporates a Wallet to which users may store their Passport if they so choose to. This could be for example to avoid repetitive NFC scans.

To provide users the choice of Wallet instead of having to always NFC scan a Passport:

Add scan attribute with value false to your request:

curl --request POST \
     --url https://api.yumipass.com/checkid/v1/requests \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
     --header 'x-yumipass-api-key: <YOUR API KEY>' \
     --data '
     { 
"claims": [ "given_name", "family_name", "nationality" ],
"scan": false
}
'

If a user does not have any Passport in Wallet, then the above choice will not be shown and user must perform the NFC scan irrespective of the scan value.
