prepaid card with international standardization of outer dimensions and the position of the contact surface of the implanted semiconductor chips

摘要

A credit card 2 with international standardisation of the external dimensions and the position of the contact areas of the implanted semiconductor chip 1 is constructed in such a manner that the semiconductor chip 1 is arranged on a removable plug-in part 3 which is significantly smaller in its dimensions compared with the credit card 2. This plug-in part, together with the credit card surrounding it, remains useable for the previous credit card applications. If it is pressed out of the credit card, it can be applied as independent minichip card in much smaller terminals (Figure 1). IMAGE
