As this double click shortcut only works with an Apple Pay registered credit card, it lacks simplicity on many other countries Apple Pay isn't available that take advantage of Passbook Passes because iPhone users have to turn on BLE and the stores need to have iBeacons to alert the customers, making it difficult or expensive while stores already have barcode readers (even without NFC). So why not remove that restriction enabling customers show up, double click and present their passes? Simplifying and helping Apple Wallet & Pay grow.
