You should already have specified daily online and offline limits for ATM and POS transactions with your vendor switch. You may want to contact them to verify exactly what those are. If you need to adjust them, you will need to request that change from them. Also make sure to update your settings in CU*BASE as they are used for the default limits for new card orders.
NOTE: Currently, the only switch that does NOT check for daily limits (meaning they come from CU*BASE settings ONLY) is PEMCO. In all other cases, the switch is responsible for controlling the limit checking, and CU*BASE stores them specifically for use when creating new cards. If you change your limits at your vendor, you must also change them on CU*BASE, and vice versa, to keep them in synch.
