Barcodes are ubiquitous these days. Here's a UPC-A barcode. Can you decode it?
For those of you who don't have a barcode reader at home the 95 bit binary representation of this UPC-A code is:
10101100010010011010111101101110110111011000101
010111001010000101100110100010010010001100110101
Once decoded, ignore a leading 0 (if you have it) leaving you 12 digits. Also ignore the last as it's a check digit. Using the remaining 11 digits the cache is at:
39 AB.CDE 10F GH. IJK
