That's a mouthful.
OGNL does have an 'in' operator
customer.creditCards[0].type in [ 'AMERICAN_EXPRESS', 'VISA', 'DISCOVER' ,
'MASTERCARD']
note that you don't have to do toString() if type is already a string ;
ognl's equality operator ( == ) already uses equals.
If it's not of type String, you might try projection :
[ 'AMERICAN_EXPRESS', 'VISA', 'DISCOVER' , 'MASTERCARD'].{? #this.equals(
customer.creditCards[0].type ) }.size() > 0
