Week 8: Smartcard Technology – NFC, RFID

With the addition of a NFC tag reader in the new Apple iOS 14 update released on the 16th of September allows majority of patients with a smartphone to also receive personal information on their individual devices as well as the kiosk.

Smartcards:

A contactless smart card is characterized as follows:

  • Dimensions are normally credit card size. The ID-1 of ISO/IEC 7810 standard defines them as 85.60 × 53.98 × 0.76 mm (3.370 × 2.125 × 0.030 in).[1]
  • Contains a security system with tamper-resistant properties (e.g. a secure cryptoprocessor, secure file system, human-readable features) and is capable of providing security services (e.g. confidentiality of information in the memory).
  • Assets managed by way of a central administration systems, or applications, which receive or interchange information with the card, such as card hotlisting and updates for application data.
  • Card data is transferred via radio waves to the central administration system through card read-write devices, such as point of sales devices, doorway access control readers, ticket readers, ATMs, USB-connected desktop readers, etc.

Contactless smart cards can be used for identification, authentication, and data storage. They also provide a means of effecting business transactions in a flexible, secure, standard way with minimal human intervention.

Smart cards are being introduced in personal identification and entitlement schemes at regional, national, and international levels. Citizen cards, drivers’ licenses, and patient card schemes are becoming more prevalent.

RFID:

RFID devices usually do not include writeable memory or microcontroller processing capability as contactless smart cards often do.
