#GET DATA

• CLA = 0x80
• INS = 0xCA
• P1 = 0x00 for public data, 0x01 for NDEF data, 0x02 for Cash data
• P2 = byte offset divided by 4, only used for NDEF data
• Response SW = 0x9000 on success, 0x6A86 on undefined P1 or if the offset is past the end of the data
• Response Data = the data as previously stored by the STORE DATA command
• Capabilities: NDEF for P1 = 0x01

Reading NDEF records is segmented, since a record can be up to 512 bytes and a secure channel response carries at most 245. P2 is the offset in 4-byte words, so valid values are multiples of 4 in the underlying byte offset. The card returns as much as fits, at most a multiple of 4 bytes; the client keeps requesting the next segment until the returned length is shorter than requested. Passing an offset at or past the end of the record returns 0x6A86.

Public and Cash data are small enough to always fit in one response and ignore P2.

#Version note

Since 4.0 this command requires a secure channel.
