Following a visit to my local friendly Pingo Doce Supermarket today, it transpires that the supermarket chain owned by Portuguese Retail group, Jeronimo Martins, has again started, as from 2nd January 2015, accepting Multibanco Debit Cards for purchases of values less than 20€. It appears that the lifting of the ban also applies to credit and debit cards.
This restriction, introduced a couple of year ago, was a real pain for the consumer.
