Slashdot | Germany To Roll Out ID Cards With Embedded RFID:
'The production of RFID chips, an integral element of the new generation of German identity cards, has started after the government gave a 10-year contract to the chipmaker NXP in the Netherlands. Citizens will receive the mandatory new ID cards starting from the first of November. The new card allows German authorities to identify people with speed and accuracy, the government said. These authorities include the police, customs and tax authorities and of course the local registration and passport granting authorities. There are some concerns that the use of RFID chips will pose a security or privacy risk, however. Early versions of the electronic passports, using RFID chips with a protocol called 'basic access control' (BAC), were successfully hacked by university researchers and security experts.'

This touches on much of the future tech from both Suki series. With all of the networked computing gear people carry around normally, in the 2030's, commercial tracking and targeting of ads is simple and accurate.
Government use of individual tracking is limited, some through laws, mostly through fruits of most monitoring not being allowed in criminal cases.
