Revenue, Performance Obligation [Abstract]
Revenue from Contract with Customer [Policy Text Block]	The timing of revenue recognition, billings and cash collections results in billed receivables, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities) on our consolidated balance sheets. Other than contracts with customers with financing arrangements exceeding 12 months, revenue recognition is generally proximal to conversion to cash, except for Lottery instant products sold under POS contracts. Revenue is recognized for such contracts upon delivery to our customers, while conversion to cash is based on the retail sale of the underlying ticket to end consumers. As a result, for such contracts revenue recognition under ASC 606 does not approximate conversion to cash.
