This part of ISO 28560 is not able to encode the DSFID if the tag does not contain a programmable DSFID register. In this case, ISO 28560-2 encodes the DSFID in the first byte of the working area of the tag. To take this situation into account, the content parameter (see Table 1] shall not take the value 6 on RFID tags encoded according to this part of ISO 28560.
If and only ifthe tag does not contain a programmable DSFID register, it is permissible to distinguish tags encoded according to this part of ISO 28560 from other encodings by verifying the cyclic redundancy check (CRC) encoded in the basic block (see 7.2).
Data shall be written to and read from the tag as specified in ISO/IEC 18000-3, Mode 1, such that the first bit transmitted to or from the tag is the least significant bit of the first field of the basic block. This field contains the content parameter (see Table 1). From that starting point, bytes are transmitted to or from the tag in order from left to right, with byte 0 to the left of bytes 1, 2, and 3, as shown in the memory map in Annex B.
If the size of the RFID tag is greater than 256 bits, extension blocks (structured or unstructured) can be inserted after the basic block up to the capacity of the chip. If extension blocks are inserted, the order of these is optional. The length of an extension block is determined by the first byte of the block. The type of extension block is defined in the following two bytes.
Table 1 shows for each data element defined in ISO 28560-1 the data block where it is encoded, how it is encoded, and the values it can take. Note that some data elements can be encoded in different data blocks. The data blocks are described in Clause 7.AS NZS ISO 28560.3 pdf free download.
