Loading computer programs in blocks

Method for loading computer programs into a memory of a portable memory object having a contactless operating mode, particularly a chip card, from one or more transmitting devices EM1, . . . , EMj, . . . EMp, p being a whole number, the method comprising:

• the computer program is divided into n blocks BLK1, . . . BLKi, . . . , BLKn, n being a whole number greater than 1;
• a piece of information I(n) indicating the number n of blocks to be loaded is transmitted to the portable memory object;
• the blocks BLK1, . . . , BLKi, . . . BLKn are loaded without contact into a memory of the portable memory object from a transmitting device EMj wherein j is in a range from 1 through p;
• each block BLKi is counted in the portable memory object;
• the loading of the blocks BLK1, . . . , BLKi, . . . , BLKn is interrupted during the loading of a block BLKi due to an interruption in communication between EMj and the card;
• in response to establishing of communication between one of the transmitting device EMk and the card, wherein k is in a range 1 through p:
• interrogating the card as to which block to resume loading, and
• resuming the loading of the blocks from block i from transmitting device EMk;
• and
• each block BLKi loaded is counted in the portable memory object.
