Some people have small digital tablets - I work alongside some voluntary history researchers and they carry small tablets (with a sim card) that they use to scan things etc. Have bigger screens on them.Not being pedantic, but what do you mean by this - ".....or other digital device"?
I also make "contactless payments" with my bank card.
Can I use that to enter the stadium then?
Actually - I tell you what next time you are up in Middlesbrough for a little while I will take you around the digital history trail about a mile from the ground and show you how it all works on my phone.
