excel data grid

i have a series of ID's
the ID's get scanned across a series of dates
an ID is not scanned more than once a day, and will not be scanned EVERY day.
so i get a list like this

2831B342000065AB      3/12/15
2831B3420000659F      3/12/15
2831B342000065A1      3/12/15
2831B3420000659E      3/19/15
2831B3420000659F      3/19/15
2831B342000065A3      3/19/15
2831B342000065B2      3/19/15
2831B342000065B2      3/23/15
2831B342000065B3      3/23/15
2831B3420000659F      3/23/15
2831B342000065A2      3/23/15
2831B342000065A3      3/23/15

what i want is this

                                      3/12/2015      3/19/2015      3/23/2015
2831B3420000659E                                 1      
2831B3420000659F           1                    1                      1
2831B342000065A1           1            
2831B342000065A2                                                       1
2831B342000065A3                                 1                    1
2831B342000065AB              1            
2831B342000065B2                                 1                    1
2831B342000065B3                                                       1

any shot at getting this to transpose in such a way?

(obviously there are MANY more than 12 scans and 3 days)

Insert Pivot Table, select those two columns.
Grab the serial numbers, drag to Rows. Select dates, drag to columns. Select dates again, drag to Values (will be set to Count, which is already what you need.
Results are unique serial numbers in the rows section, while the dates line up in the columns, and the count numbers in the data field
