Picture this: You’re approaching a potential client, only to realize your business cards are in your other black tote bag.

Bummer.

But wait a minute: It’s 2018. Why are you still relying on business cards anyway? Try HiHello, it’s a contact exchange app that lets you create and share digital contact cards.

Create your contact card with whatever information you want to include (name, email address, job title, phone number, etc.). Have a side hustle? You can make another card for that. When you’re ready to connect, HiHello produces unique QR codes for each contact card that people can scan with their smartphone cameras to add you to their address book.

As for those cards in your other tote? You won’t be needing them anymore.

The New York Public Library has amassed an amazing collection of New York City photographs from the 1870s-1930s. Prior to the digital age, a look at this vast collection would have required a trip to the Schwarzman Building at Bryant Park (a trip worth taking if you haven’t.) However, you can now access the photographs through OldNYC, an app that lets you use your location to see what the area around you would have looked like in the past.

The collection of images, which began being assembled in the 1920s as a way of preserving the past of a changing city, come from the NYPL’s Milstein Collection. A significant portion of the collection is courtesy of Percy Loomis Sperr, who extensively documented New York City in the early 20th Century.
