The MESCard is a service offered by the McMaster Engineering Society that gets you discounts at local businesses. All you have to do is present your MESCard and you’ll get a special engineering deal! All first years will get their MESCard during Welcome Week, however upper years can sign up for the Card using this Google form: http://bit.ly/15PvrE9.
The MESCard also serves as a way for the MES and the Faculty to identify you as an MES Member. Be sure to have it on you so you can attend free engineering-specific events throughout the year!
