Multiple cards clubbing
Multiple cards clubbing
Without considering any link with the bank. Lets say offline payment, how easy will it be to have a single card, instead of multiple cards. ? That single card will be having information and data of the multiple cards.
It depends on the Payment scheme you want to use. If you want to define your own stored value scheme for Micro Payment then either CIPURSE™ or Desfire card is best option, as it supports the creation of multiple applications. You cannot use these cards if you want to follow the VISA or MasterCard scheme. In this case, choose Java Card which supports the VISA or MasterCard application. Create and personalize the multiple instances of application using data of the multiple cards.
In case of a strict complaint with VISA or Mastercard, you need to check specifications w.r.t card printing, as some application information is printed on the card.
Technically, there are several chip card products available supporting multi-application capabilities.
Refer here to how you can implement multiple application on single-chip product/card. do watch the videos.
