"...one small irritation I’ve encountered with the SMRT is that the “EZlink” RFID card system used in Singapore conflicts with the two other RFID subway cards in my wallet (the Shenzhen Tong and the Hong Kong Octopus card), so as I pass through the busy turnstyles, about half the time I get an invalid card error, causing much irritation among the people behind me as I sort through my RFID card collection to pick out the EZlink card.
"Having seen Japan’s Suica system integrated into mobile phones, I thought, why not stick the EZlink chip inside my phone? Since the EZlink card also serves as a payment card, I can get around the city with nothing but my phone, buying beverages at 7-11, and paying taxi, bus and train fares while texting my buddies without carrying a scrap of cash.
"As a general note, transplanting RFID chips is a much cleaner solution from both the legal and technical perspective versus cracking the security and programming your own RFID to be compatible with the existing payment system.... (((Why even bring that up? Cracking RFID security for the sake of a lousy boarding pass is like committing three redbox felonies for the sake of a long-distance phone call.)))

"I’m guessing the TSA would not be entertained if they found this on me given the recent use of mobile phones in cargo bombs…" (((There needs to be a special term for this kind of lookah-me viral hacker chic... "Hi, I'm Julian Assange, I can bring superpowers to their knees with the press of a button, only I wouldn't want to..." I guess "hacker chic" oughta do it. Lotta hacker chic here.))))
