Converting TLV to NSMutableDictionary
EMV data is received in TLV (Tag, Length, value) format: 950500000080009B02E8009F2701018A025←-
A339F26080C552B9364D55CE5
This data contains the following EMV tags/values:
Tag Length Value
95 05 0000008000
9B 02 E800
9F27 01 01
8A 02 5A33
9F26 08 0C552B9364D55CE5
An example how to create an NSMutableDictionary with these values follows.
-(NSMutableDictionary
*
) createTLVDict{
NSMutableDictionary
*
emvTags = [[NSMutableDictionary alloc] initWithCapacity:0];
[emvTags setObject:@"0000008000" forKey:@"95"];
[emvTags setObject:@"E800" forKey:@"9B"];
[emvTags setObject:@"01" forKey:@"9F27"];
[emvTags setObject:@"5A33" forKey:@"8A"];
[emvTags setObject:@"0C552B9364D55CE5" forKey:@"9F26"];
return emvTags;
