Lars Erik Holmquist, a research leader at the Mobile Life Center at Stockholm University and the Swedish Institute of Computer Science, provides some insight into the use of Super Urban Intelligent Card (SUICA), an RFID-based smartcard, for sensing, networking, and data access. Holmquist highlights that the technology is presently used to increase convenience and reduce human contact. Apple's iPhone 3G and the accompanying Appstore with RFID based smartcards makes easier downloading and installing a mobile installation. Various games are constructed in collaboration with students to explore new forms of wireless applications, when handheld computers with Wi-Fi became available. Holmquist highlights that PushMusic with RFID-based smartcard has allowed the creation of an application in which music could be spread among users through automatic and manual recommendations.
