The report, which comes from TechCrunch citing unnamed sources, says that the potential price of the acquisition could be relatively low:
The price may be under $100 million, according to our sources. That is either a huge bargain or a testament to Softcard's difficulties as an enterprise: sources tell us that AT&T, Verizon and T-Mobile — the three carriers that started Isis in 2010 — have collectively invested hundreds of millions of dollars in the joint venture.
TechCrunch goes on to note that its sources indicate that Google may be interested in the company for its patents and existing carrier relationships.
Do note that this news should be taken with a large grain of salt for right now, as nothing has been officially confirmed. However, it would be interesting to see what impact a potential Softcard acquisition could have on Google Wallet.
