DUB, your mobile business card (for BlackBerry)

By Ryan Blundell on 6 Oct 2009 12:39 pm EDT

It may be an exaggeration, but sometimes it feels like my wallet won’t stay folded. It’s not only because of membership, credit and debit cards; it’s all of the business cards I seem to accumulate. I’m not sure how they all get there. Maybe it’s a case of the right hand not knowing what the left hand is doing. In this case, the hand is nabbing every card in sight. I also know that I’ve lost access to some extremely important contacts, all because of a misplaced card. Besides your wallet, your corkboard or cubicle wall could contain enough business cards to make it look like a shingled roof. A cleaner, greener approach is to use your address book (duh!), but this can be time consuming. For some, vCards could also be an issue. “Here’s your card?” Here’s MY card, compliments of DUB.

By using DUB, you can easily send and receive detailed contact information right from your BlackBerry smartphone. Your risk of outdated contact information is greatly reduced thanks to DUB’s ability to automatically maintain an up to date contact list. So, leave your George Constanza sized wallet at the door and check out DUB.

About DUB

DUB is brought to you by DubMeNow Inc; who’s “Chief Cliff Jumper” Manoj Ramnani, mapped out his business plan on a simple airline napkin. The application is currently in version 2.5 and will take up 477KB of space.

The first thing you have to do is create your own card. This can be done on your computer, or directly from your BlackBerry. Account and contact management can be performed on either as well. Each card is designed to capture important contact information. On top of your standard info such as; phone information, company and title, you can capture IM account information, company websites and links to your Twitter and LinkedIn accounts (among others). You can even upload a photo, so contacts can put a face to your name. So the next time you receive a business card and you find yourself in a situation that requires one from you as well, whip out your BlackBerry. Email, or send a text to your new contact including your DUB card. When they ask what you just did, tell them “…my card…”. Oh, and you have permission to sound as suave as humanly possible. A DUB card will display your information in a compact “business card” style. This card will include links to your website, social media info, email or whatever you have shared. I did have issues viewing the contact picture on my BlackBerry, but it did work well on my computer.

If you happen to run into a fellow DUB user, you can very easily give them your DUB ID. This is a quick name you create in order to exchange contact information. It may be a lot easier to input than to remember an email address. Yet another option for DUB users is to utilize the included Locate feature. If you both select this feature, you will be found and prompted to exchange information. How’s that for a quick meet and greet?

From your BlackBerry, you can also manage your DUB contacts, create/edit DUB groups and view received DUB business cards. I was impressed by the depth of additional features that were available. You can send LinkedIn invites, tweet about the new cards that are sent/ received and sync DUB contacts with CRM tools. For those *sigh* special moments, DUB will remember where and when you met someone and display the location on Google Maps. While the UI was fairly simple to understand, I did find navigating with only the trackball a bit of a hassle. I’m hoping to see keyboard shortcuts in future builds. There’s a lot of potential to be found in DUB, but the features will truly shine when more users join the ranks.


I’m hoping to see more and more users jump on the DUB bandwagon, because its benefits can be easily seen. Instead of worrying about entering and managing contacts, you can actually get to know them. Contacts are updated and seen, just as your own updates will be seen by others. I think that with a little more tweaking with the UI, DUB will be a fantastic addition to your list of applications. DUB can be found, for free, in BlackBerry App World.


  • see visually appealing, easy to read DUB business cards
  • contact information is automatically updated
  • links and invites to various sites


  • navigation is a tad slow
  • Doesn't provide full account management as the desktop version does

DUB, your mobile business card (for BlackBerry)


does it allow the service to access all your contacts on your desktop or just your device?

I can't imagine opening up a contact list for autoupdates and not have it be a source for clients, etc. to get spammed.

I mean why can't you just send your info as an attachment?
Ryan, thoughts?

The first time this app was covered in this forum (or maybe another forum) I expressed concern that Dub's servers might be storing all transferred contacts, since that would be the easiest model for this to work. I don't see how handheld-to-handheld communication could be set up to work reliably; the only way to do that would be to use PIN-based communication, and some people use more than one BlackBerry, while everybody swaps out to a new or replacement device at some point. So how else could this work without storing all the contact info on a central server operated by Dub?

I hope the developer, who is posting to this thread, responds to your question to clarify how this works and to dismiss my concerns.

As far as your question as to the advantage to buying this app versus using any of the built-in ways of sending contact info, like emailing a vCard, this app is designed to dynamically (and automatically) update your contact info on every device you've ever sent it to using this app whenever any of your info changes. For anyone who views that as an advantage, I think it would be a sizable one.

We do not use the information in your contacts list in any way. We don't even upload your phone's contacts to our servers, we just put the DUB information into your phone's contacts. We only use your information in the manner described in our privacy policy, which you can see at: https://www.dubmenow.com/privacy

Let me know if you have any additional questions. Thanks!

It won't register - just keeps saying "no internect connection available" when I've got full bars and can surf 3G to my heart's content.

I went to the site and it worked perfectly. I am looking forward to using your product.

Unfortunately, when downloading from App World I got an incompatible message.

Thanks for the great review. We're excited to see so many people using Dub (about 5k BlackBerry downloads per day)!

We have some great new features and updates coming soon. Stay tuned!

To the comments above - it is compatible with both Curve and Tour.

Chris Hopkinson

Yep I was able to DL it to my Tour from the site not from App World. I like it. Is there a way to scan it biz cards that I already have or do I have to do it manually... Thanks.

If you go to your BlackBerry Address Book - highlight a contact and push the Menu button - the first option is to Send DUB card.

Please feel free to email any questions to me directly chris@dubmenow.com

So it only works with other people who have Blackberry type devices? Too bad it doesnt work with regular cell phones. Unfortunately I still run across a lot of people how still use regular cell phones. i guess I will still have to carry a deck of cards on me. :(

You can email your card to anyone and they can use the web to accept if they don't have a BlackBerry, iPhone or Android.



Received message from BB App World, "this application is not available on your device or for your carrier".....so what's up???? is it the Storm or Verizon Wirless or both which are not compatible with the DUB???

Shame theres no support for Europe...doesnt even show up in my Appworld listing probably due to the fact that i live in the UK.

wish devs would get their act in order and realise that there are BB users from all over the world...its not just North America that has BB users lol.

I'm also concerned about the use of information collected from my contact list. I've emailed the company because their Privacy policy is not that clear. I'll report a response if I get one.

**** After contacting the company with my concern, here is the response****

We do not use the information in your contacts list in any way. We don't even upload your phone's contacts to our servers, we just put the DUB information into your phone's contacts.

i can't download this app for the life of me! Does anyone have a .jad file so I can just download it over-the-air from my Tour???

going to w8 till i can send to non smart/non user(app) that would be so much handier(send self info no re-text)everytime

I downloaded and it looks cool but it needs to be able to send to non users so that 70yr old clients can just open and save to the phone and not download apps etc... Cool concept but the requirement that the recipient needs to have the app is going to really limit this application.

I was looking for such business card for my blackberry from last couple of months, at last i found it along with its description, which seems very helpful, your post is quite health to read and it worth reading.

I downloaded this recently, but after learning how it worked, I ended up removing it. I really like the idea, but I'm not a fan of

1. Having a secondary phone book on my phone that I have to access through an app. It would be nice if DUB sync'd with my contacts and updated them that way. I got really excited when I saw this app, because that's what I believed it would do. I wouldn't call it false advertising, just lack of details.

2. To add a contact, a recipient has to download DUB as well. This is the main reason I removed the app. Sure, it's nice to be able to send my card to someone digitally, but again, I had hoped that the recipient would be able to sync the DUB contact up with their Outlook, or whatever contact list they had. I hate making someone have a certain program just to save a contact list.

I know, I know, these are all fantastical dreams, and my standards are too high, and I know I'll get some flak for this statement, but: look at the i-phone app "Bump." Same concept, but instead of a separate program, the contacts you gain go straight to your contact list. Simple.

What DUB IS good for is sending a business card. I wouldn't use it for the contact list, because that's all through the website or through the app, but sending a card that someone can then transfer manually to their contact list is still pretty cool.

Thanks for checking out DUB! Couple things.
1. DUB does sync with and update your existing address book.
2. Just like LinkedIn or Facebook, DUB's value comes in the connection. That's how we're able to automatically update your address book any time a contact updates their info.
3. Again, we do sync with your existing contacts like Bump (and Bump only works from Bump user to Bump user). Difference is we also auto update your existing address book, you can send your card to anyone and we work on BlackBerry as well as iPhone, Android and Win Mobile. Plus, with DUB your contacts are backed-up. Lose your phone, just reinstall DUB and they return.

We working on some other ways to simplify the process, so some of your fantastical dreams will be coming soon!

Please feel free to email me if you have any additional thoughts.


Chris Hopkinson

Hey Chris, Thanks for the swift reply! I don't know why, but for some reason I was mistaken about the DUB contacts not syncing with my own. While I don't want to make my recipients download DUB (Outlook sync support would be amazing), being able to keep my contacts up to date on my native blackberry address book is much better than I had originally thought. I'm reinstalling as we speak. Thanks again!

Chris, I'm asking this in the forum since it could benefit the CrackBerry nation. Is the transmission of data across the DUB network secure? I'm not a techie and I'm not clear on what you store on your server and what you don't. I have to assume DUB stores our contact info on its servers; how else could our contact info be instantly updated as well as restored if the phone is lost. Any information you can provide would be helpful.

Hi Schlinger - happy to provide more info. We use https protocol (this is the same security your bank provides when you access online account info) and the transmissions are encrypted. All the connections are done on a secure port. Hope this helps.


just installed dubmenow and i find it hard to scroll through my card to update the fields. storm compatibility needs to be improved

Hi Chris:

This is a wonderful concept, one which I think a lot of folks were waiting for.

Just to follow up and add to some of the questions posted to you:

1. Besides our devices and the persons who receives our contact info. is our contact information store anywhere else?

2. If I do not want a person to receive any updates regarding my contact info. how do I stop this?

3. How can I create more than one business cards?

4. If I purchase a new devices and install DUB, where is my contact information being downloaded from?

5. On your web site can you show a diagram of how the process moves from point to point. Similiar to those types of diagrams which vendors selling wireless routers will layout to explain the connections and how information travel?

Thank you for answer all of our questions and concerns we are motivated to buy your product by this.

Thanks again.

Happy to help. We're seeing a lot of users, so you must be right about people waiting for it.

1. On a https protocol, encrypted port. It's the same security your bank provides protecting your online account info.
2. You can't remove a contact at the moment, but that feature will be in future release.
3. Same as above. Not available now. ETA is December.
4. See 1.
5. You can email or text your contact info to anyone. Our locate feature uses GPS, cell triangulation and some internal algorithms to make connection.

Hope this helps.


This product sounds great. However, before I download it, I would like to confirm that it gives me the option of sending my business card to contacts currently in my contact list. I do not want the program, upon installation, to search all of my contacts and automatically send them my new card and a request that they download the software.
