Regnerischer Nachmittag 
Der Post ist ja nun schon etwas her, scheint aber noch aktualisiert zu werden. Was bedeuten die aufgeführten AIDs bei den jeweiligen Apps? Z. B. bei “Mobiles Bezahlen” von der Sparkasse sind u. a. auch Amex und RuPay dabei. Ich kann mir nicht vorstellen, dass irgendeine Sparkasse in Deutschland RuPay-Karten ausgibt oder?
Das sind die AIDs, auf die die Apps reagieren. Bei der Mobiles Bezahlen App hat es aber wohl eher den Hintergrund, dass die Entwickler den Source Code anscheinend ’nicht aufgeräumt haben‘. Vielleicht wurde die Basis für eine indische App verwendet…
Ah, ok, jetzt dämmert’s. Also bei direktem SELECT mit diesen AIDs kommt von der App eine Antwort, nehme ich an. Danke für die Antwort!
Glaube so wars vor 1 Jahr. Habe gerade keinen Reader um das zu überprüfen
