Member Cards






A credit card sized contactless smart card with built-in memory for storing the most up-to-date bonus points, prepaid dollar value and administrator defined member profile. Utilizing 13.56Mhz radio frequency smart card technology, the transfer of data between smart card and Terminal or Display unit requires no physical contact.



Since the most currentinformation about the members are stored on the Member Cards, this reduces the dependency of real time information from the centralized database server like those in the traditional magnetic stripe card loyalty systems.

Two types of Member Cards are used: (a) Ultralight Card with less memory (48 bytes) and lower security for loyalty system only and (b) Classic Card with more memory (15 sectors of 48 bytes each) and high security (Triple Des) for both loyalty system and prepaid subsystem.

48 bytes of basic member information are stored on the Ultralight Card and one of the sectors of the Classic Card in the following format.

Basic information (48 bytes) format stored in both Ultralight and Classic cards:

  • Unique card ID (4 bytes) assigned using the Master Card supplied from the factory.

  • Current bonus points ( 3 bytes, max. point = 16,777,215)

  • Unique Company Code (2 bytes) assigned using the Master Card for a company's identity.

  • Accumulative bonus points ( 4 bytes, max. point = 4,294,967,295)

  • Member last name ( 10 characters)

  • Redemption or Purchase item name (10 characters)

  • Administrator defined member profile (12 bits combination of questions and choices)

  • Identifier for Item Name ( 1 Character)

  • Date of birth

  • Redemption point or Purchase Value ( 3 bytes, max. point = 16,777,215 or max. value = 167,772.00 with 2 decimal points )

  • Language selection ( 4 choices)

  • Current prepaid dollar value ( 3 bytes, max. value = 167,772.00 with 2 decimal points)

  • Member Card expiry date





Color graphics can be printed on both sides of the smart card using 4C color offset printing. In order to make good quality printing and 500 dpi artwork is recommended. Quality designed printed cards can act as a good advertisement tool to promote company image.
