Contactless smart cards can be kept in a briefcase or handbag and are therefore
extremely convenient to use (Figure 13.3). Transponders can also be fitted into wrist-
watches.

13.2.3 Benefits of RFID systems

The replacement of conventional paper tickets by a modern electronic fare management
system based on contactless smart cards provides a multitude of benefits to all those
involved. Although the purchase costs of a contactless smart card system are still
higher than those of a conventional system, the investment should repay itself within a
short period. The superiority of contactless systems is demonstrated by the following
benefits for users and operators of public transport companies.
Benefits forpassengers
• Cash is no longer necessary, contactless smart cards can be loaded with large

amounts of money, passengers no longer need to carry the correct change.

• Prepaid contactless smart cards remain valid even if fares are changed.

•

The passenger no longer needs to know the precise fare; the system automatically
deducts the correct fare from the card.
