Parameter
Description
timeLimit
Specifies the maximum time, in seconds, allowed to complete the total

language, choose an application, and online processing. If this time is
exceeded, the transaction will be aborted and an appropriate Transaction
Status will be available. Value 0 is not allowed.

0x01 = Magnetic Stripe (as alternative to EMV L2, card swipe causes abort
of EMV L2)
0x02 = Contact smart card
0x04 = Contactless smart card (not supported at this time)
Note: Multiple Card Types can be selected, for example: Set this byte to 3 to
read both Magnetic Stripe and Contact Smart Card.

0x01 = Bypass PIN (not used on this reader)
0x02 = Force Online (not used on this reader)
0x04 = Acquirer not available (Note: prevents long timeout on waiting for
host approval) (causes “decline” to be generated internally if ARQC is
generated)
