A smart card is a security token that has an embedded chip. Smart cards are typically the same size as a driver's license and can be made out of metal or plastic. They connect to a reader either by direct physical contact (also known as chip and dip) or through a short-range wireless connectivity standard such as Near Field Communication (NFC).

Contactless ticketing is the primary technology for transit fare collection. As technology matures, fare media reliability and durability become increasingly important as the harsh, demanding transit environment requires fast, easy and reliable transactions every time.
Automatic Fare Collection System (AFC) is a contactless smartcard-based end-to-end solution for fare collection and payment. The state-of-the-art solution is uniquely designed with the demand of revenue services for modern transit operation in mind.
Radio-frequency identification ( RFID ) uses electromagnetic fields to automatically identify and track tags attached to objects. The tags contain electronically stored information. Passive tags collect energy from a nearby RFID reader's interrogating radio waves. Active tags have a local power source such as a battery and may operate at hundreds of meters from the RFID reader. Unlike a barcode, the tag need not be within the line of sight of the reader, so it may be embedded in the tracked object. RFID is one method for Automatic Identification and Data Capture (AIDC).
