Imagine sitting in a\nrestaurant and you're being presented the bill, most people will do a\nquick scan of the meals and drinks consumed (and non-malignant errors\nare frequent in that business).\n\n\u003e     It's already very short if you can do without Android Beam, e.g. on\n\u003e     Android 2.3.\n\u003e \n\u003e I think IsoDep based protocols must bypass Beam - when I scan my\n\u003e e-passport there's no beam animation.\n\nEverything except Beam bypasses Beam (-:  Beam is an Android-specific\nprotocol. I assume it would also be possible to write an own NDEF\nimplementation on top of the low level NFC APIs. I want to try as soon\nas I have a second NFC-capable phone, preferably Android 4.4.\n\n\u003e     Even the current ~10 second roundtrip is a huge improvement to the\n\u003e     status quo. I recently tried to buy a subway ticket and it took me 7\n\u003e     full minutes (just for the payment process)!\n\u003e \n\u003e Then that subway kind of sucks ;)\n\nYou can't really blame the subway for a broken payment process.\n\n\u003e Have you been to London and used Oyster?\n\nYes, it was a complete disaster. Obtaining a ticket took even longer --\nca. 45 minutes. Boarding the train took some additional seconds,\ncompared to no overhead in Germany where we simply don't have any gates.\n\nOn top of that, you walk more (in tunnels) than you get driven around,\nget tracked on each movement and if you want to get your (monetary)\nchange, you need to wait for another 45 minutes.\n\nThe upside is, when going by public transport in England I always feel\nlike Mr. Freeman in City 17  (-:"}
